I agree on the ASUS M5A97, but if you haven't bought the cpu yet, get the i3 2120 and a p67/z68 for a better upgrade path. 965 is pretty much the end of the road for amd. The i3 2120 has the same performance in games and can be upgraded later to an i5.
Steamroller may be a different socket. Still the 965 is perfect for a cheap system. Don't forget that most games are built around 6 yr old console tech and those that are built for PC - Max Payne 3 etc can and will take advantage of 4 cores. At 1080p you don't really need Intel and I wouldn't go lower than a quad in 2012.
Now i wanna sell my 6970 and get a 7950. http://www.newegg.com/Product/Product.aspx?Item=N82E168... with these PCI express 3.0 Cards, they are reverse compatible but can they saturate an express 2.0 MoBo and degrade the bigger cards performance? Would a guy need to get a more expencive MoBo?
