For 90$ less, I would get a GTX 470. 5870 just isn't a good buy right now in terms of price/performance. http://www.newegg.com/Product/Productcompare.aspx?Submi...|14-162-049^14-162-049-TS%2C14-261-070^14-261-070-TS%2C14-187-110^14-187-110-TS Do note that this means you can't really crossfire as an upgrade path.
All right as far as right now this is what i have.

Scythe SCKTN-3000 92mm Sleeve "KATANA3" 3Heat Pipes CPU Cooler ($28.69, Not sure about this tho, Im thinking of overclocking so i thought i would get a better heatsink..but its cheap so i dont know if it would be better))
OCZ Diesel 4GB USB 2.0 Flash Drive Model OCZUSBDSL4G (Free)
AMD Battlefield Bad Company 2 Gift Coupon ( Free, Not sure if its the full game or what it is. Combo with the processor)
Thats about it. The grand total is $933.02 thats including shipping. Think it turned out ppretty well.
The 5850 is about 150W at load, two of them + the CPU is max 450W. The other stuff no more than 50W. So we're looking at 500W. Say 550 in the most demanding stress tests. So, 650W is plenty. And it's very unlikely to have a 5850 crossfire setup running at full capacity.
