I want to get a new Graphics card specifically for CUDA acceleration in Premiere Pro. The Two cards I'm looking at are:
3GB Geforce GTX580
2GB Geforce GTX680
The 680 is obviously faster, more power efficient and has new technology implemented which to me seems more specifically designed for games. However, it has 1GB less RAM then the 580. My question is, which is more important for CUDA acceleration, faster card or more RAM? Which will prove more beneficial in terms of performance (price not an issue)?
I will be running it on a 4.6ghz 17 PC with 32B RAM. Any help would be greatly appreciated.
