The HX corsairs are really good psu's .
You dont even need 8 gig of RAM for a gamer so 16 gig is massive overkill and a waste of money .
The GTX 570 has good performance . So does the 560 ti and the Radeon 6950 . All work well at 1080p resolution .
i got the ram for like 35 bucks
and what about this card XFX HD-687X-CNFC Radeon HD 6870 , is that a decent card?http://www.newegg.com/Product/Product.aspx?Item=N82E16814150563
