Comparing the Power of i7 Processors in PC and Mac Pro Xeon

I am reviewing the pros and cons between purchasing the Mac Pro with 8 core (new neh. 2009) and purchasing a Dell system with the processor such as the Intel Core i7-940. The price of the Dell and Apple systems show a substantially higher total price for the Apple with similar memory and extras for both, but I am having trouble comparing the performance of the different Intel processors in each brand. I believe that the basic architecture is different, and it appears that the i7-940 processor is a quad processor but has 8 threads. Can anyone educate me on how to compare the two since I have not found any literature on point?

Both the i7 and the new Xeons have 4 physical cores and hyperthreading, which makes them able to run 8 threads.
They are both virtually the same, with the exception that the Xeon is able to be used in multiple CPU systems and has extra pathways to 'talk' to a second Xeon, The i7 does not and cannot work in a multiple CPU system.
Other than PRICE, and being marketed as a 'server/workstation' chip there is little other difference between the two, actually.

My phone won't turn on. I have tried the Power button home button several times and even held it for over 3 minutes.. When I plug it in it still won't respond to itunes PLEASE HELP!! A little water got in it but it was like a drop or two..

My Iphone 4g, won't turn on, I have tried the power button + home button several times and held them for over 3 minutes. It won't even respond to Itunes and I can't restore it because of that. A little water got into it before it completely shut off but it was like little drops.. Please HELPP.
I also have tried to put it in rice and left it there for 9 hours and it still doesn't work

A drop or two of water may have been enough to cook it. If it was bad enough to prompt you to put it in a bag of rice, then I'd venture to guess it was more than a drop or two.
Try putting it back in the bag of rice and leave it there for several days.
If that doesn't fix it, then you're more than likely looking at paying for an out of warranty replacement.
Water and delicate electronics don't generally get along well.

I did a factory reset on my late 2008 MacBook from a Snow Leopard disc. It installed fine, but as soon as I began to use the computer (safari) it froze. Couldn't even force quit. So I held down the power button to turn it off, and now it won't start up.

So I held down the power button to turn it off, and now it won't start up. It goes to the grey Apple screen and just sits there loud as can be. Help! Please keep in mind I've not done anything like this before and am going to need a little hand-holding. Thanks in advance.

Hi. Don't worry it's nothing serious. Insert the Instal Disc (Snow Leopard) and press the C button while turning on the computer. Once you see the desktop, go to Utility and choose Disk Utility. Select the Macintosh Partition on the left window pane and then click on Repair Disk and Repair Disk Permissions on the bottom right corner. Wait for both processes to finish. Click on the Apple icon (top left corner) and choose quit. Your computer should restart. See if it reboots normally. If not you can always reinstall the OS following the same steps. Good luck!

I have bought the wireless keyboard for my iPad. I was working for a day but now the power light won't stay on and as such won't connect to the iPad. I have changed the batteries but still no difference.

Not knowing which wireless keyboard you bought, it is difficult to be specific. but ...
it is quite normal for the keyboard's power light not to stay on - it is a way of conserving battery power.
Try this:
turn you keyboard off
on your iPad go to Settings > Bluetooth
if your keyboard is listed under Devices, then touch the little blue i to its right and choose Forget this Device
now reset your iPad: hold both the Home and Power buttons down for about 10 seconds until the Apple logo appears, let go promptly when the Apple logo appears and wait another 30 seconds for your iPad to turn itself on
After your iPad is back on again go back to Settings > Bluetooth
now turn your keyboard back on and see if it appeard under Now Discoverable
if it doesn't read your keyboard guide to figure out how to put it into Discovery mode
touch the listing for your keyboard under Now Discoverable, it should now appear under Devices
touch the listing for you keyboard under Devices, and choose to pair with it.

I have a mac book pro running Lion 10.7.4 and every time I use Google Earth The computer crashes by lowering a black curtain and then asking me to hold the power button down until it closes and press the power button again to restart it. Can I fix this?

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

I wanted to watch it on our MacBook for sound and clarity, and every time I accessed it, it locked up. To the point that the only solution was holding down the power button.
Everything else worked, and I could freely enter information and open other Facebook entries, but when hitting the "play" button or clicking on the video it immediately bought up the spinning beach ball, and would never clear. Any solutions?

Did you try viewing the video in a different browser? Firefox or Chrome maybe?

I have purchased the VGA Connectors for both a iMac and Macbook Pro so that i can connect my promethean board projector to the computer and I can not get the image on the screen. Does anyone have any suggestions?

thank you, I have the adaptors so glad that would work. I just heard adaptors burn out often. So Just thought for my main iMac computer, a plug would be best. I will get one once I move.
Any other suggestions or things I should know about apple products in Ireland. I know there are no Apple stores there.
An adaptor doesn't burn out. It merely serves as a means to connect the power prongs on your device to the power supply.
I believe you are thinking of a transformer, which you do not need. A transformer converts one voltage to another.
You don't need to do that as the power supply of modern electronics can take almost any worldwide voltage.
Look at the label on the device. It should indicate the input power acceptable of 100-240 VAC, 50-60 Hz.
Additionally, I found the adapters cheaper in the UK than I found them in the US. They were available in most supermarket chains. I wasn't in Ireland, so I can't say one way or the other.
If you have something that doesn't have that input power spec, it would require a transformer.
On other items like electric clocks or things with motors, you can connect them up to a transformer and the voltage will be correct, but the frequency may not. For clocks, that will cause them to not keep time well. For motors, they will burn out.

Hey 1Jerry,
Thanks for the question. You'll want to delete and re-add your iCloud account (utilizing the new Apple ID address). When prompted, opt to keep as much information on your device as possible. The following article provides information on how to do so:
iCloud: Change iCloud feature settings
http://support.apple.com/kb/PH2613
Turn off iCloud completely
Depending on whether you want to stop using iCloud on all or only some devices, do one or more of the following:
On your iOS device’s Home screen, tap Settings > iCloud, then at the bottom of the screen, tap Delete Account.
Thanks,
Matt M.

The Mac Pro - the desktop computer - does not support Airdrop, if that's what you mean.

SADLY not as i downloaded an upgrad to my original PAGES/
i have in the meantim had to open www.icloud. then from there import the file that i am working on and then check on ipad if it uploaded/ yes it did.
but what a waste of time as it doesn not save any changes done automatically back in the cloud....
i am now downloading the new LION and hope that it will fix the problem
i cant find any other way. I was lead to believe that you wrote, it saved automatically, on to the cloud, you then opened anohter device in anotother country even, and the new file was there, waiting, in its latest version.......
and the same magic was supposed to happen in reverse.
It doesn't/
if i have to open a browser, go to www.icloud....why on earth did they not just leave us an icon to drop it in in that case?
I hope the new lion will help resolve the isssue/
any other ideas> keep em coming...thank you so much.

I brought Pages, and it showed in the purchase history. But in my new Mac pro, It needs me to buy again. I register already, it didn't show "downloadable". How can I do?
