Right now I am torn between two cards. Here are the links to them:
which one of these cards should I get? I heard that the 570 is better than the 6970 but I like the fact that it has 2 GB of memory. What are some of the pros and cons and which card would you guys suggest on buying. I am planning on getting two eventually of whichever one I get. Case size isnt an issue I have a full tower, I guess that I should also add that my main monitor is a 47 inch LCD HDTV. Any help and suggestions would be awesome!!!!
Given Wikipedia, the 6970 is almost twice as powerful as the 570 (based on gigaflops).
With such powerful cards, you'll need a fairly high-powered PSU to go with it. The 570, according to the TDP in Wikipedia, needs 219 watts of power (which means you'll need 18 1/4 amps on a +12V rail) and the 6970 has 250, meaning you'll need at least 21 amps on a +12V rail. You should always include more amps than this for the CPU and other hardware.
