That's debatable, actually. Generally, yeah, you're right, but in this case it's different.
BFG 8800GT, $187 after shipping. http://www.newegg.com/Product/Product.aspx?Item=N82E16814143118&Tpk=8800GT%2bBFG
It has a single-slot cooler, with heat spreading inside the case rather than outside, and that's a problem with the NZXT Alpha case (only 2 fans)
MSI NX8800GTS 512M OC GeForce 8800GTS (G92) 512MB, $187.59 after rebate and shippinghttp://www.newegg.com/Product/Product.aspx?Item=N82E16814127325
Yes, the GTS is 59 cents more, and needs a rebate, but in exchange it solves the cooling issue, it overclocks better, and it has 128 stream processors instead of 112.
