G4 MDD for gaming (Tiger & some classic) single v dual questions . .

I'm setting up a computer for gaming.
OS X 10.4.11 (or 10.3 if thats better suited?)
Unreal, Icewind dale, Giants, Sacred, Shadow Bane, etc . .
All the older games 00 -04
Would it make more sense to use a 1.25 single cpu vs 867DP or 1Ghzdp?
Since tiger does not spport dual core, I'd assume most of the games don't either?
I know the 1.25 (or even a 1ghz single) runs much cooler than the dual under load.
Basically is a dual a waste without using Leopard or software that supports multi core cpu?
Any ideas?

When you say tiger is dual processor aware, how is it and when does it benefit?
Multi threading is supported in dual processor machines, allowing for the distribution of tasks (within one or with multiple tasks), making for faster performance. Boot, OS background services and processes, multi tasking, etc., are all improved and utilize the OS X multi processor/multi threading ability.
Granted, the processes are relatively rudimentary (as compared to forthcoming OS versions), but the support is there.
A major factor is that accompanying software must also be multi processor aware to gain benefits beyond OS X functions.
also how does this matter if the game is not dual processor aware?
No (or little) benefit will be derived from multi processors with SP processor optimized software.
Some CPU intensive gaming will be improved, simply due the the multithreading ability of the OS X core services.
Some DP aware software define which tasks are broken between two processors. In the case of UT2004, the audio portion is assigned to a separate processor, to allow more computational power of the other processor to be applied to graphics.
Other software simply allows the OS services to assign threads as the system protocols dictate.
This is only possible with a multi processor aware OS.
Actually, the ability of the OS to be DP aware began in OS 9. 3rd party software, however, was slow to take advantage of the ability.
Currently, multi processing aware software has to add multi core awareness to gain full benefit of current machines like the Mac Pro.
This is one of the big areas of development in OS X 10.6.
(When I used the term dual core, I just meant dual processors as in the mdd series)
I figured that you know the difference, but many don't. Keeping the terms straight is for the benefit of clarity and for all readers.

  • Need a printer for both Tiger and Classic

    I posted a question before (July 13) about trying to get my HP psc 1315 All-in-One to print from Classic applications when running Classic in OS 10.4.7 on my new pre-pentium G5. Now I just want to know if anyone out there knows if there is any All-in-One unit that I can buy that will print in both Classic and Tiger.
    The problem seems to be that the new Mac is emulating OS 9.2 rather than just running 9.2 as a background system. Because of that, printer drivers will not mount in Classic -- at least that's what HP and Epson and Apple all tell me.
    So if anyone can tell me of a reasonably priced All-in-One that will do what I want, I'd be extremely grateful.
    S/R
    G5   Mac OS X (10.4.7)   Pre-pentium so it supports Classic

    If you don't want to buy any more hardware and have a printer connected to a desk top or laptop computer you could try printjinni. You would need to share the printer to make it available to the app (locate the printer in printers & faxes right click the printer and select share from the content menu)

  • New Macbook Pro 2014 for Gaming / casual use

    Hello there! I currently have a 2011 13" Macbook Pro with
    Intel HD Graphics 3000 512 MB
    16GB RAM
    500GB Harddrive
    and a 2.4 GHz Intel Core i5
    I really like to play video games but with this current setup ^ its very sluggish and I get very low FPS
    I'm considering getting the  13-inch MacBook Pro with Retina display and with the 3.0GHz Dual-core Intel Core i7, Turbo Boost up to 3.5GHz 
    My questions:
    Will this computer be able to handle a constant 60fps in most games? (Borderlands 2, portal 2, Bioshock Infinite)
    And I've heard other places that this computer also has a Nividia graphics card that it switches over to when you play anything that requires more than the Intel 4000 that it comes with.
    Thanks for the help!

    Hi there!
    No it wont.
    Macbook Pro's hardware are mediocre for gaming. In your specific case, the 13" does not offer the possibility of a dedicated graphics card, only comes with Intel Iris. The 15" one does, the NVIDIA GT 750M with 2gb, yet it's weak for gaming above 40-50 fps, also dual-core processors are not very powerful these days either and you will most likely experience heating issues on intensive gaming sessions. If you like gaming Mac is not very efficient for it, unless you get a mac pro, but of course you would loose portability. The 27" iMac can be set with the GT 780m, it has 4gb but its still weak since its a mobile graphic chip as well, even the 5k iMac uses almost identical hardware setup than the regular iMac but with an AMD chip (also 4gb ram), while the 5k looks great with such hardware it is unable to handle smooth gaming on that resolution as well.
    Dont get me wrong, I'm not here to trash Apple, at the office we work with around 8 to 10 macbook pros but none of them, not even high end ones are able to game smoothly, in fact, some games run better on windows via bootcamp than OS X.
    Hope it helps.

  • HT2431 How can I best run old CDs written for Mac OS 9 (Classic)on a MacBook Pro with OS 10.7 with VMware Fusion

    I have some old CDs of medical drawings and other references that were written for Mac OS 9 (Classic). These are still excellent resources but I now  have a MacBook Pro with OS 10.7. I also am running VMware Fusion.  How best can I run these programs?

    MacBook Pros & OS X Lion don't support classic operation.
    Suggest you buy an older Mac that will run OS 9 or run in classic mode while booted into OS X Tiger or below.

  • Which Imac would be better for gaming?

    So i've got a choice between these two models -
    £1329.60
    3.1GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz
    TB Serial ATA Drive @ 5400 rpm
    8gb Ram
    NVIDIA GeForce GT 750M 1GB GDDR5
    Apple care
    27 inch model
    3.2GHz quad-core Intel Core i5
    Turbo Boost up to 3.6GHz
    8GB (two 4GB) memory
    1TB hard drive1
    NVIDIA GeForce GT 755M with 1GB video memory
    Apple care
    £1407.60
    Basically, the decision is down to, do I want a slightly better graphics card and bigger screen, or a smaller screen and better processer?
    I just want to gauge opinions, i'll be using it as my day to day computer as well, some video editing, but nothing too strenuous. How big is the difference in graphic and processing powers.
    Thanks for your help

    With all due respect the question was "which iMac would be better for gaming?".  Key word here is 'better', not 'perfect', not 'ideal'; just 'better'. Unqualified answers and/or sweeping statements do very little to contribute to a discussion, let alone answer the question under consideration.

  • What are the possible approches for hosting a product(custom SP application) for multiple clients on a single SharePoint farm?

    We have a product which is a custom application based on SharePoint Foundation 2010. Right now, for each of our client we create a dedicated server and host the application in the standalone deployment. Now, the requirement is to host multiple clients in a
    farm deployment.
    Challenges are: 1. The product has same name for the wsp that is deployed on different client servers as of now. How to distinguish for different clients on same farm
    Currently the product specific css and jquery is in 14 hive. These files will be of difefrent versions for different client. How to segregate that?
    How many web applications is recommend to be created in a single SPF 2010 farm? What are the challenges?
    There are a couple of DBs created in SQL for the application. What is the best way to separate those for the client?
    Essentially its the same product but with different versions for each client that we want to deploy in a single farm. What is the best practice to tackle this?

    For the most part, these are not SharePoint questions per se, but product-specific questions you'd better ask the vendor about. To get in some more detail:
    1. It totally depends on the scope of the solution. If its global, then you're out of luck and any changes you make affect all instances that use it. Better ask the vendor about it.
    2. Not that many, let's say < 10, assuming you're web applications have separate application pools. Check out  http://technet.microsoft.com/en-us/library/cc262787(v=office.14).aspx#WebApplication for
    more info.
    3. This is very application specific and really should be answered by the vendor. Not related to SharePoint at all.
    4. Again, really depends on the product so better ask the vendor.
    Good luck!

  • Can I have Tiger enclosing classic on an external drive

    I'm on Snow Leopard 10.6.3 on a late 2009 Mac Mini with an external LaCie drive to which I back up my home folder each night (don't use time machine). I moved up from a G4 mac mini which had Classic as well as Tiger on it.
    Would it be possible if I cloned my Tiger including Classic system from my old G4 mini to a separate partition on this current LaCie disk, for this partition to show up as a possible alternate startup disk in my System Preferences> Startup Disk when using my present Intel machine? I know Classic can't work under Intel, but wonder if the System Preferences here would allow me to boot into my external disk partition on Tiger/ Classic restarting.
    Why I would like to try this is simply that although I bought a new scanner and photoshop elements 8 to work with Snow Leopard, and it does, I had an old scanner and Photoshop 6 working out of Classic on my previous mini and it just worked better, gave me more options, than the new setup. So I miss using it on my monitor, though I can still do so on my G4 laptop.

    You can however use SheepShaver (http://sheepshaver.cebix.net/) to run MacOS 7.5.2 thru 9.0.4 in emulation on an Intel Mac... Its not a perfect solution but it does work for many apps (I've got Sheepshaver with OS8.6 and Photoshop 6 working on my Intel iMac)...

  • IMac for Gaming using Win XP Pro

    Early 2006 I purchased an iMac 2.0 w/ 2G RAM using x1600 ATI card w/ beta boot camp using XP Pro for gaming purposes.
    Now I want to expand my horizons a bit to a new iMac with the same idea as above.
    My gaming includes Battlefield 2, COD4, and soon Crysis. So here is the system I want:
    iMac 3.06 w/ nvidia 8800 GS which I read is NOT the 8800 but some other nvidia card. I want to expand to 4G RAM, BUT replacing all the RAM with either Crucial or Kingston for Dual Channel. Will XP Pro be stable w/ 4G dual channel? Will this system utilize DX 10. w/ the nvidia card on this Mac? If I get Crysis, I want to be able to set everything on HIGH. Are there any Driver problems that I should be aware of?

  • How good is a Macbook Pro with dual video cards for gaming?

    I've been a PC guy my whole life (aside from my iPhone which I love). My gf has been pushing me to try out a mac and considering how my PC laptops have a pretty good track record of dying on me or encountering some other problems after a year or two, I can't help but consider making the investment. The only thing is, I'm a big gamer and usually get the latest games. I'm not super tech savvy though I do my research and get a sense of what kind of specs are better and worse.
    In terms of gaming, I always assumed that more ram = better. In that sense, I'm a little put off that even the most expensive MacBook Pro only comes with 4 gigs of ram (which is what my year and a half old laptop has now) especially when it seems most newer laptops have 8 gigs minimum for a fraction of the price (and 16 gigs if you're willing to spend as much as you would on the most expensive macbook pro). Does RAM somehow work differently on a Mac or is it truly that little?
    Also, how does the whole dual video card thing work, does that mean I'd be having the power of those two cards put together?
    Personally, I've been leaning towards the Asus G53SX-NH71 because I can buy it for less than the cost of the cheapest macbook pro and as far as gaming purposes go it seems to have more power than even the most expensive Macbook which costs over double the price.
    Am I missing something here? Do the dual video cards really bring that much to the table or for gaming purposes am I better off with a PC?
    Thanks.

    I've been watching this forum for years, and I'll have to say that gamers are not a big group around here.  A few things.  First, getting 8GB of RAM for the MacBook Pro is cheap.  Most people either don't care, pay Apple to do it, or, like me, DIY.  The max you put in a MBP is 8GB, so no 16GB, unless you were looking at the iMac or MacPro.
    Second, there is no dual video card in a MacBook Pro.  There is an integrated video card, an Intel HD3000, which shares RAM with the CPU, or a discrete video card, an AMD, various versions on different MBP's.  The Intel is for low battery usage.  The AMD is more powerful, and it's to be used when you've got power.  The video card has more applications than just gaming, but also in video and photo editing. 
    No one here is going to talk you into one platform or another.  If you are only going to game in Windows, then it's a waste to get a Mac.  If you're going to game in Windows but want the Mac side to do everything else, the build quality and elegance of the Mac will far exceed most products out there.  You can run Windows in Boot Camp natively, and as I understand, gamers love it, because the Mac is actually a better Windows machine than most Windows machines.  But I don't play games, so I have no proof. 
    So the choice is yours.  And we could argue all day long about the side by side comparison of a cheap Windows machine vs. the Mac.  You are using the price vs. price comparison that is a false dichotomy, ignoring how one values various features.  For example, the trackpad on a MacBook Pro far exceeds (and I mean light year exceeds) anything on any other laptop out there. 
    I spent 10 minutes answering your question.  I'm not debating you on x vs. y.  The choice is totally on what you're going to do.  Most of us are trying to contribute to the world, so gaming is low on the needs list. 

  • Macbook Pro 15'' options for gaming and college

    Hi there Apple Community!
    I'm having trouble choosing the best cost benefit for a new Mac. I'm a college student and my main priority is to have a mobile unit to cary with me for classes. I'm also a gamer, and since this will be my main computer I'd like to have one that could also run games like Civ 5 and WoW smoothly. Therefore I believe the best option for me would be the cheapest 15'' MBP.
    However, both the price and the extra weight scare me. I'm not confortable with walking around with a R$ 6,600.00 notebook (about US$ 3,300.00 - I'm in Brazil and thanks to taxes all the prices are overrated ).
    I'm studying options to reduce the risk of walking with such a valuable piece of hardware around while giving me what I need where I need, and after some time I've matured the idea of having more than 1 device.
    My first option would be to get me cheapest 13'' MBA along with a Mac Mini - the one with the Radeon 6630M videocard on it. They cost together about the same as the 15' MBP, and would give me both a lighter option to go to college and a dedicated videocard for games, though this card is weaker than the one in the MBP - and I'm not sure how well this card would handle the games I want to play.
    Another option would be to get myself the both cheapest 21'' iMac (with the same videocard as the MBP) and the cheapest MBA. This would be a bit more expensive than the MBP, but no big deal, and I'd still have both a decent unit at home for games and the mobility I need for college.
    My last option would be to get the 13'' MBA and use the rest of the money to assemble a gaming Windows 7 PC. This would be my last resort, though. I know I can assemble a terrible machine with this budget, but I believe I could have what I need - decent (not extreme) gaming experience at home - from a Mac, even if I have to use Bootcamp.
    I'd like to know from you who own Macs what you think about these options. I intent to make my purchase this month or the next, as my classes begin in August. What would u think to be the best combination? Or is the MBP the best option? Thanks in advance for any thoughts.

    Thanks for the reply, OGELTHORPE. Refurbished products were the 1st thing I thought when I saw the cost of a 15''MBP. Unfortunately there's not even a link for this store in Brazil's store. I'm not sure, but I believe this is because of the mistrurst we brazillians have upon refurbished equipments sold by many other companies that fail to meet quality specs - some companies even try to push them as 'new' to the customers... I know that US Apple follows refurbishing rules to the letter - not hard to find people around the web saying that they got a nice deal for buying a refurbished Apple and that they would do it again. I wish I could buy a refurbished unit from the american Apple Store and have it delivered to Brazil, but I believe this is way too much to ask for the 'free shipping' they offer...
    As for gaming, I do like it, but I'm not looking for a gaming station - otherwise I'd look for a PS3, Xbox 360, etc. I do want a computer to complement my studies at home - this is my main focus after all, and it would be desirable if this new computer could also run some games for me to play when I can.
    I'm just not satisfied with the Intel HD 3000's performance (some people say they are even weaker than the previous nVidia models they replace). This is why I'm trying to get my hands on one of those new Radeon videocards.
    Anyway I've heard that Apple may show some new products on this week's presentation at WWDC.Let's hope something good is coming.

  • Optimize Mac for Gaming with Bootcamp?

    Hi, I have a Mid 2012 MacBook Pro with Windows 7 installed using Bootcamp. Because I'm a student my parents aren't exactly thrilled with the idea of getting me a Gaming PC, but since I'm not a hardcore gamer I think I can make do with what I have. How would I be able to optimize my gaming experience with my Mac? In other words, whether it is with software, or upgrading some hardware, how can I make my Mac usable for gaming. And trust me, I'm not hoping for 60FPS having games on the highest setting kind of thing, something that is decent quality is all I want. I feel that my Mac's current specs and hardware is almost at where I want it, but some optimization to increase efficiency and performance would be really nice. Thanks in advance!

    you are stuck with whatever graphics it has which is usually the main resource.
    Did you buy with just base RAM? which processor? you can't change the cpu.

  • Which is better for gaming and why?

    Hi,

    Could anybody please tell me which is better for gaming (main purpose and best performance)?
    The HP Envy looks great but I don't know much about AMD Quad Core.....
    Also, is it possible to upgrade the graphics card on the HP Envy ( AMD Radeon 6630 to a better one) via a HP centre?
    It seems to run most games quite well, but I need it to be able to play new games for at least 4 years more (college), while not factoring in the costs for any possible graphics card upgrade....
    Please help!!

    Thanks Huffer _ very useful.
     I wasn't aware that there was a heat problem with the i7 processors, my dv8 runs at around 42 to 52 degrees, mind you I don't really put it under much load. I use it to play Blu-ray ISO files on my projector and for photo editing (Adobe CS4), it's an 820QM.
     I have also changed the thermal compound to ICDiamond and drilled holes in the speaker cover to improve air flow, that made a difference too.
     @ abhishekmaha
     Don't take my comment to seriously, although I think it has some truth to it, it was meant to poke a bit of fun at you. 
     Heat has always been one of the biggest factors when it comes to any computer, designers try to make them thinner, lighter and cheaper and those types don't work for gaming very well. They're OK for the occasional one, but not on a regular basis. I believe that if you game on any machine that was not meant for it, you will not get 4 years out of it _ 2 years.
     I wish I could tell you different, but I am not going to lie to you.
     Heat basically affects 3 things on a laptop, the solder that holds the components on the motherboard, any mechanical moving parts, eg the hard drive, fan _ and the battery. You can remove the battery to prolong its life when gaming.
     Heat breaks down the solder over time and the mother board simply stops working as far as the hard drive, it stops spinning because the tiny bearing(s) in there dry out and seize up.
     If you don't want to use a cooling mat then prop up the back of the laptop, hanging it over the edge of the table will expose the fan intake, but will block off other vents.
     60 degrees is a bit warm too, 50 is better or rather, the cooler the better. What ever machine you get, make a note of what the temps are when you first boot up and when it's hot. The idea is to get an average so you can judge when it is dangerously getting hot.
     P.S. Be sure and give Huffer a kudos too.

  • Re: using the iMac i5 for gaming

    I have recently purchased an iMac I5 which I'm delighted with. I realise that it will be anathema to many but my question is could you use it for gaming? I am thinking of downloading Dragon Age Origins but cannot get my mind around how I could operate the keyboard as it is the small Bluetooth one. Has anyone used their's for gaming and how did they get round the keyboard issue?

    You can plug any USB keyboard into your Mac. F-keys typically are mapped as they should be. Some extra keys can also be mapped with Apple menu -> System Preferences -> Keyboard and Mouse -> Keyboard -> Full keyboard access. Alt and Windows keys are in reverse locations from an Apple keyboard. Logitech, Kensington, and Microsoft all have Mac versions of their keyboards with the appropriate key mapping. As long as the GPU and processor and RAM meet the qualifications on the game's recommended system requirements on its box, you can run it on your iMac. I've not played the game in question.

  • What is the best Router for Gaming?

    Alright, at the moment I have a "G" wireless router, which I bought it for pure gaming reasons, well I am thinking about upgrading 'cause I am having some lag and poor connections and I want to enhance my connection for online play.  I won't lie I am a addicted hardcore gamer, so I need a good router! ^_^
    Well I been looking at this WRT330N , which this one interests me a lot!
    http://www.linksys.com/servlet/Satellite?c=L_Product_C2&childpagename=US%2FLayout&cid=1166859632665&...
    I know it's about $200 but I am willing to spend the money if it's worth it! If anyone can share anything about this router or a cheaper and better router please do so!

    I started shopping for a wired router to handle a claimed higher speed from my cable provider. I want something that runs at full incoming wire speed. I did not think I would care a lot about special gaming features. One of the techs at work uses the GamerLounge which is made by D-Link and he loves it for gaming. It runs a little over $100. It has a number of features to help automate the setup for gaming and to help debug gaming connection problems. I do not know if Linksys makes anything that is specifically targetted at gaming. You might want to read the various hardware reviews and decide which features you think will be important to you. Linksys has product documentation that describes the products but you will have to understand the terms used in the brochures to decide which device might be best for you. I have a Linksys for wireless support and it is rather slow compared to a wired connection because I run encrypted. If you want to run games on wireless, then published benchmark results may be the number one item on your list. Some routers may have much faster wireless performance than others. Cost will probably be a factor but more expensive does not always mean better. I have a WRT54G V5 and Tom's Hardware has a review discussing some of the serious limitations in V5. I stopped using it as a main router and went back to an old 10 Mbps wired router connected to the cable modem to get better performance. The WRT54G V5 sort of works when used as a wireless access point but Windows file and printer sharing do not work. So ... it all depends on which features are most important to you. Absolute best case is to talk with a friend who has a working setup that they like. Then you can decide if their priorities for choosing features match your priorities.

    What is better sky fire or flv for gaming sites

    You cannot play flash games on the iPad.
    Skyfire only plays back video from some sites.
    Any browsers claiming to play flash do so by sending the video to their computer, transcoding it to mp4, then stream it to you.
