I am building my first PC for work and gaming. I'm not a huge gamer, but would like the ability to play recent games (BF3, Crysis 2, D3, etc.) at high settings. The highest resolution my monitor is capable of displaying is 1920x1080p. Is it worth it for me go for the 7850, or should I save some money and get a 6870? I'm trying to stay under budget, and the extra 110 dollars seems like a lot extra to pay for something that I might not even use the full potential of. My processor is i5-3540, btw.
