As I know PD supports CUDA and Quick Sync.
Currently I use Core2duo 3Ghz with 4 GB RAM and GeForce GT9600. (Win XP 32 bit)
Is it worth to:
1. change GPT to GTX460 and leave CPU ?
2. change CPU to Corei5 2500 with Z68 (for using Quick Sync) ?
3. make both changes ?
I would like to see optimal growth of performance (now 100 minutes project takes about 6 hours of rendering)
any advices or links to interesting articles will be appreciated
