MB - CPU - I am looking for the BEST fan or whatever to keep this cool. Could someone point me in the direction on Newegg.com as to what cooler will keep this the coolest? Price is not a problem.
Also I would like to know what is better. The HD 4870 or the HD 4890. And is the MB good for overclocking and also Crossfire ready? If not, can someone help me find one that will work with the processor and Crossfire?
That motherboard is only so you can use DDR3, which is really unnecessary as of right now. Just go with this motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E16813128358 That processor isn't compatible without a very expensive board, which you probably won't get close to using all of it's processing power. Just go with Intel's Q9550. The Tuniq Tower works very well for me, but you need to modify the bracket for it to fit into that case, which is an easy fix. The 4890 is obviously better, but if you said that money isn't a problem, go with the 4870x2, or better yet, put those babies in crossfire.
Neither of these boards supports crossfire. The board Enigma posted supports SLI only, and the board Eddie posted does not support either. If you want crossfire plus I7 support in an reliable package, it is going to cost you. The board below supports both, but it's price varies from $200 to $270... http://www.newegg.com/Product/Product.aspx?Item=N82E16813136063
