Thanks for the reply -
Well i need to rip about 200-300 dvd's to mp4 format, rendering youtube videos and also rendering videos for iPhone format.
I chose the i7 for HT and i have also heard openCL acceleration is very buggy in Premiere so i chose the 660ti for CUDA and the adaptive vsync feature in games
Thanks for all your replies everyone -
I think I'll get an i5 3570k if the i7 has no considerable improvement in transcoding and i think I'll stick with the 660ti because I like the feature set nvidia has put into it. I'll buy the 750w PSU just for future-proofing.
-Just one more question will a faster optical drive increase performance while ripping dvd's?
