Re: Best Graphics Card for CS5

According to some non-scientific tests, it is estimated that only about 100 cores are actually used so even if a card has triple the cores, only 100 of them are being used. So performance may increase in the future when more cores are utilized but it doesn't make that big of a difference currently.

Re: Best Graphics Card for CS5

Thanks a lot for the replies, appreciated. I think I MIGHT still go with a 570 just to have it future-proofed a little. There are still a couple things I'm unclear on. On the Adobe Cuda page, it says that encoding and decoding are not gpu-accelerated. I should know this by now, but what is the difference between rendering, decoding, and encoding in CS5.5 and where exactly do all of these take place?

As far as I know with a Cuda card, the preview window is sped up, some FX are sped up when using in real time, and the final rendering output is sped up as well. But the encoding/decoding thing confuses me.

So when you say playback, you're talking about playing it back in the Preview window correct? I'm not sure of the differences between hitting Enter, 0 on the keypad, and spacebar...

And thanks again for the replies, almost got this understood 100%.
