Additional Comments/Main questions: Not sure if everything will fit in the Antec 900 or if I should go with a HAF 22, found good combo deals on both. Unsure if the mobo is good enough/large enough to comfortably fit 2 6870's. Should I wait and buy another 6870 later? Or buy two now so I get one before they run out? Sapphire I've heard to be a good brand.

Im going 955 because I plan on upgrading to the new Intel CPU's when they come out and it looked like the best price/performance for now.

OS - Windows 7 OEM 99.99 -

GPU - http://www.newegg.com/Product/Product.aspx?Item=N82E168... - 239.99 - Extra budget room for another of these cards if I should buy now

MOBO - http://www.newegg.com/Product/Product.aspx?Item=N82E168... - 89.99 - Seen this one recommended before, looks nice, is there better around this price?

Hard Drive - http://www.newegg.com/Product/Product.aspx?Item=N82E168... - 69.99 - Went with the Samsung Spinpoint because its recommended so much and SSD's are too expensive for me right now on a just gaming computer.

Total comes to - $928.87 before the 30$ rebate on one of the combos so about $898.87 after
if I add another 6870 it comes to $1169.86 before and $1139.86 after.
Thanks in advance for your help, I put in alot of time searching to hopefully not waste yours and not sound retarded.
