Quick question about GPU memory

post #1 of 7
Thread Starter 
Ok so probably a noob question but for some reason a google search turned up nothing on this, so I'm probably just phrasing it wrong. But here goes anyways:

So when buying a new GPU for folding, what will yield better results, a card that has a higher core clock/memory clock, or a card with more physical memory on it? (850/4008 with 2GB RAM vs 900/4212 with 1GB RAM)? The cards are within 10 bucks of each other, so figured I would check and see which would produce more points out of the box (without any tweaking) and then go from there. Any input is welcome.

shaders are the most important, but a higher clock speed is better than more memory.

Shaders above all else. Mem clocks have little impact.

Also, the amount of memory alone makes no difference; however, sometimes having different memory means the card is slightly different (take the 640mb and 512mb models of the 8800GTS), so that may make a difference.

Less memory= less heat/more room for pushing the shader clock.

The amount of memory has no impact on folding. For instance, the 768mb GTX 460's get the exact same PPD as the 1GB ones.

Yeah what about a 1GB card vs a 3-4GB card?

Still doesn't make a difference in PPD.
