i have an e8400, 4gb @800 mhz and an hd6870, and i played farcry 3 at 1080x1920 in high detail, without any significant lag, so i'm pretty sure you'll be able to play, unless of course, the games dont want to install, cod ghosts refused to install because it required 6gb of ram. i'm in the same situation as you and i'm out of money, so right now i'm gonna put maybe 2 gb more of ram and attempt to play the next gen. i thought about buying new hardware, but damn! prices are high and the fact that my country's currency is worth about a quarter of the last time i got a pc is not helping me.
