yeah i dont get it either...
its not like the 300W limit actually limits power consumption of systems anyways...
people who want extra power get up to 4 300W cards...

actually it would be more power efficient to allow a single vga with 400W then, cause then people who want ultra performance would run 2x400 instead of 3x300 or 4x300...
and people who want this kind of power overclock anyways, so then the limitation doesnt matter at all...

300W is clearly not enough and limiting cards... so im surprised why nvidia and amd are not pushing for more...
think about it, if there wouldnt have been a 300W limit then nvidia could actually have launched a GTX480 Ultra with 512sps and a 350W tdp and a massive heatsink...

and ati could have launched the 5970 at full 5870 clocks instead of clocking it down...

ah well... if ati and nvidia dont care...
