Somebody who knows about graphics....I have a PS3 and a computer with a GTX 670...not willing to buy a new card just for the game....but do you think it will look better on the computer? It barely passes the min spec. I also have a i5 3.6(or 3.4 i don't remember) and 8gb ram.
With a similar setup to yours people were hitting 50-60fps on Ground Zeroes @1080p.
