135/100 = 135

=35% better perf per what, which is almost exactly what i was saying.

so because we know perf per watt, and perf, we can find the watt by doing simple algebra. (which i didnt do lol)
Even then.. Its lower than 15% by doing the algebra :X
If you use stalker as comparison base (credit to DarthShader at Beyond3D forum), you get around 92% TDP of GTX480 -.-

Imagine stalker on GTX480 runs at 60fps.
17% higher perf would be 70,2
You know TDP of GTX480 is 250.
60/250 = 0,24.
0,24+(0,24*0,27) = 0,3048.
70,2/0,3048 = 230 TDP.
230/250 = 0,92.

nVIDIA must be insane to launch this card at those prices. What the hell are they thinking?
