After doing a bit of research, the I-5 760 seems like it holds up extremely well with modern games and wouldn't cost me a fortune like any I-7 would. Everybody recommended that mobo with the processor especially if you were planning on crossfiring, or SLI. Which I may if I can get another 4780. I trust Corsair as you might be able to tell, so the RAM speaks for itself. And the H50 seemed like a good heatsink to go with since my case isn't extremely large and the heatsinks on the board and RAM take up a lot of room.
Thats what I've got so far. If anyone has any recommendations, advice, or if I looked over anything for the set up, please feel free to say anything.
Newegg's price for the CM Hyper 212+ is good, you may want to shop around for the Arctic Silver.
Also, if you'd wait, at 1st quarter 2011 Intel's Sandy Bridge will have prices as low as i5-750/760, while having performance nearing i7. I recalled there's a Tom's article here somewhere that "Sandy Bridge brings big promises".
but if you go this way wait a little for the new ATI 6 series, due 22 this month.
If you are in the urgent need of a new and better system. Replace the proc, RAM and mobo. Postpone the GPU later and get from the HD6xxx series. HD4870 can still serve you well untill you get the new HD6xxx.
If you can still wait, postpone averything untill Sandy Bridge, Bulldozer, and HD6xxx are on the market.
