I'm about to install a new graphics card and don't have much of a budget and have decided on a Sapphire ATI 5450HD.
I have the choice of 512Mb or 1Gb or RAM and googling some research seems to show that unless you are gaming, there is no real reason for going for 1Gb.
In terms of my general use, I use Premiere Pro CS4 and additionally a variety of video conversion programs that I use to convert footage to various formats.
What I would like to know is whether:
a: 1Gb would improve the performance of Premiere and in what specific ways
b: Would the 1Gb generally increase the speed at which video conversion would take place.
c: Is ATI stream better than Nvidia CUDA
I know that different programs will support differing technologies, so realise that b: and c: are rather generalised questions but just trying to get some ideas based on others actual experiences.
