LOL you should read the review a bit closer. The NV40 has two molex connectors on the card in addition to pulling juice via the AGP port. Under load, it's estimated to pull 150 watts. The two molex connectors should not share the line with any device other than a case fan and each molex connector should be on a different line.
nVIDIA recommends a 480 watt minimum PSU.
Regarding performance, read some other reviews, so you get the full picture. Tom and Anand are nVIDIA's butt bois. Objectivity in the press is a lost concept with those two.
ATI cards typically do better in Direct3D and nVIDIA cards perform better in OGL.
I would think you would be more surprised if the NV40 wasn't faster in most benches than cores that are several months old. That isn't exactly an apples to apples comparison.
I'm sure when the R420 comes out, the NV40 will be faster in some benches and the R420 will be faster in others, but they will both be within 5% of each other.
