as for CPU cooling i have yet to decide on which one i will need, my room runs about 53, so i am not sure what type of cooling will be needed, also this rig will be running Vista ultimate 64 bit

Since you are not going to SLI with that video card you don't need to buy an SLI motherboard. nVidia's SLI chipsets are buggy and have many issues (just search this forum) not found on Intel chipset motherboard.

I would look at MSI Neo-3R P45 motherboard instead for $119.

Other than that nice build. You *might* want to consider 48x0 cards also. 4850CF gives 9800GX2 a run for its money, and beats it in some cases. 4870 CF should beat it easily in the same price range ~ $500.

CPU Cooler: http://www.newegg.com/Product/Prod [...] 6835233003 One of the best air coolers on the market.

actually i was looking for a VID card that was in the 3-4 hundred price range, i changed my motherbord to the

MSI P45 Neo3-FR LGA 775 Intel P45 ATX Intel Motherboard - Retail
http://www.newegg.com/Product/Prod [...] 6813130180

4850 is a STEAL for $199. You don't need to spend $400 anymore

However, if you feel you must buy 2 and CF them on a x48 motherboard.

u have a link for that

I will give you a couple:
