EVGA GeForce GTX 580 Fermi 772MHZ 1536MB GDDR5 2XDVI Mini-HDMI PCI-E Video Card

If I didn't have to buy an OS, monitor, speakers and headset it would be around 1400$. All together it is 1736. Not too shabby for a build with a GTX 580 (I think :P). Should I even bother replacing the stock fans on the h70? The two extra fans would have been installed on the mesh. Would I need that? Feedback would be greatly appreciated.

Also, should I even go with an H70? I can bump down to the H50 or H60 if there isn't much of a performance difference. I'm only planning to OC to about 4.2-4.5 GHz. Only reason I went with water cooling is because I heard it fits well with the 600t. I can even get a hyper 212 plus if it works.

sandy bridge OCs like a champ, if you want to break the 5ghz barrier though id go for a H80 or H100, but 4.5 is achievable on a 212+

[GT7R]

If you're planning to OC the gpu, go for a custom cooled one - MSI TwinFrozr, Gigabyte UD, Asus Direct CU, etc.

A single 4GB RAM module? Add another 4GB to that and you can utilize dual channel memory and 8GB of RAM are pretty common these days as they are cheaper now.
