Hello friends! I have saved up a total of 1500 dollars, and after all these years of wanting to get into PC gaming seriously I actually think I can. So I have all the parts I want in it on a list, and it comes in just under budget, and I think that I will be able to play most games, but I am unsure as to what games I may be unable to play. I will now list the biggest money items, and the main parts that determine a games fps/setting limits, and such. I am hoping I can get suggestions as to what I should change, and what I could cut down on (IF anything considering this is going to be mid-range.) By the way please list any games I would have trouble playing because I would really like this PC to last a minimum of 2-4 years, and play most games on max settings with at least 30+ fps.

CPU - Intel i7 3.2 GHz 8m intel smart cache LGA1366
RAM - 6 GB (Thinking about going to 8)
Video card - AMD Radeon HD 6950 2GB 16x PCle
OS - Windows 7 64 bit Home edition
HD - 1TB
Monitor - 24" Wide screen 1920x1080

Thanks for any recommendations, and help!
