New Member / Video Card Choice Question

Question

New CS4 Production Premium User Here.
I am building a computer system specifically for Video Editing and production for use with Premier CS4 & Sony Vegas.. Have been doing my usual amount of Over Research here and other places but have a series of issues I am having a little trouble coming to grips with.
I have been into computer editing game for a long time but strictly in the Audio Recording /Mixing area /..
Video is a new interest which has me hooked / Im also a Gear Junkie so I have to watch it. 
I will probably be back with a couple more topics but to keep this thread simple /
My first post question is the topic of Video cards: Adobes Hardware compatibility list seems a little out dated. ?
The system does not have to be an ultimate gaming rig as I am not into that / just SD & HD Video editing & 3d effects.. I need a card which will do what is needed / works well with Premier CS4 / Is not too loud fan wise / can run 24/5 and not overheat.
I also will need the ability to monitor on a HD TV with a good sound monitoring system / Midas / Bryston / Dynaudio etc;
I was considering either of the following / from lowest price to highest.
ASUS GeForce 9600GT Silent 650MHZ 512MB 1.8GHZ DDR3 PCI-E Dual DVI-I HDCP HDTV Out
ASUS GeForce 9800GT Matrix 612MHZ 512MB 1.8GHZ DDR3 PCI-E Dual DVI-I HDCP HDTV Out
ASUS GeForce 9800GTX+ Dk 740MHZ 512MB 2.3GHZ DDR3 PCI-E Dual DVI-I HDCP HDTV Out
Questions:
Is a 512mb card sufficient?
Will all of the above do what is needed for my purpose?
What about noise of heat issues.
My system could be running close to 24/5 at times.
Have not made a final decision on all components but will probably basically start of like this.
Vista 64 Bit/OS
Core I7 940
Asus Rampage 2 Extreme or a plain P6T
Antec 1200 Case / For now I will leave out the hard drives and other things on my list.
My builder suggests to stick with ASUS Video Cards because he has the fastest warranty replacement service on his end for ASUS products / plus I am a total ASUS Motherboard guy with years satisfied experiences.. (in Audio setups).
Any feedback or comments on the above will be appreciated.
Thanks / Orion

Answer 1

Thanks Members for the Feedback:
I am trying to stick just to the Video Card Issues so the topic does not get all over the map / Raid issues have already been researched & I might have a question about that later in another thread.
Witha the video card issue I am just trying to see if I can get a reply which the majority of users agree upon / not an easy task & that is were my confused state of topic started.

It seems what you have said about QUADRO cards is the most agreed upon overall from my last three months of research at various locations / The cost is extreme for these cards & I was just trying to determime if I realy needed to go that far : >$2,000.00 and up.
just for the Graphics card..
Perhaps I should start of with one of the cards I first mentioned which are dirt cheep compared to the Quadro series and replace it when I have arrived at the point where my shills are beyond my hardware limitations.

Thanks for the reference to the . >ASUS GeForce 9800GTX+ Dk 740MHZ 512MB 2.3GHZ DDR3< I was thinking this might be the best to start with / except for the reported could be problems of / Noise / card size and Heat issues if running 24/5?
Other issues you have stated also seem to be agreed upon from mny sources as well / which is why I am considering perhaps not going Raid "o" from the start / perhaps Raid 5.. / or No Raid until I see If realy need it for my own personal use level.
b conclusion to this point in the game:
Looks like If I do a top notch system following all the higher end recomendations it will cost me over $10,000.00 (if I include a capture card / raid card (Areca 1220 or 1240(don't want to get into that topic just yet)& all the extras... This is about double the investment I had planned as this is basically a serious hobby not a business venture. Plus we have not included another $6,000.00 for a half decent peosumer HD camera with a few extras. I was trying to keep the entire setup to 8 to 10 grand total.. Not including the software / so this looks like wishfull thinking at best / Ho Ho.
b remember / unfortunately my pricing reflects Canadian $$ which includes a 25% hike in pricing because our government wants the loonie (Good Name) low valued so businesses can export our products at built in 25% Sale Pricing.
Perhaps,we wont get into that topic/please, but I just couldn't resist / when I start thinking about government issues (anywhere in this world) I tend to go off the deep end as part of why I am going into this video thing is to document the destruction of our environment & the entire democratic process, which is a total farce in my neck of the woods. Nuff Said..
Again Thanks for the input and I will keep watching and perhaps cover another topic later / my goal is to place an order for a build within the next 10 days of so.
