Taking in concideration price and performance of both card, which one do ypou think is best dollar for dollar in performance and would offer best SLI/Crossfire performance in gaming and or video rendering.
overall winner is?
What do you intend on doing?
Secondary- Video rendering for Youtube..still equally important
For just $10 more you can get this version of the 660 which is a 3 GB card instead of 2.
I'd suggest the card californiachris recommended, mainly because it has more VRAM. Also, what will you be rendering in? If the software you use is compatible with CUDA, then definitely get the 660 Ti 3GB. Rendering will go much faster if your software can use those CUDA cores
