(texels/sec.)
6600 GT 4.0 billion
6800 Ultra 6.4 billion (get a 7600GT)
7100 GS 1.4 Billion (uhhh...)
7200 900 million (LOL)
7300 SE 900 million (was funny the first time)
7300 LE 1.8 billion (umm...)
7300 GS 2.2 billion (oh come on)
7300 GT 2.8 billion (well, its still no 6600GT)
7600 GT 6.7 billion (absolute budget card for DX9)
7800 GTX 13.2 billion (too much price for lack of DX10 at around $200)
7900 GS 9 billion (only DX9, but only $110, see below)
7900 GT 10.8 billion (not much better than 7900GS but twice the price)
7900 GTX 15.6 billion (too much card for DX9, too much price for lack of DX10)
7950 GT 13.2 billion (too much card for DX9, too much price for lack of DX10)
7950 GX2 24 billion (way too much card for DX9, way too much price for lack of DX10)
8400 GS 3.6 billion (this is worse than a 6600GT)
8500 GT 3.6 billion (ugh, again?)
8600 GT 8.6 billion (7900's faster for the same money, but this has DX10, not that it'd be good enough for DX10, tho)
8600 GTS 10.8 billion ($40 more than either the 7900GS or the 8600GT, but still not likely enough card for DX10, look at benchmarks)
8800 GTS 24 billion (Hey, if you got $300 and a nice power supply...)
8800 GTX 36.8 billion (If you have money to burn)
8800 Ultra 39.2 billion (If price is no object)
If you're going to compare the 7900GS and the 8600GT, the 8600 has 22.4 GB/s memory bandwidth, and the 7900 has 42.2 GB/s memory bandwidth. If you don't need DX10 right now guess who wins.
