Really you should be able to max out any PC game with a 100W card(aside extra filetring options etc.) but the PC industry has become obesed. It's not healthy to need a 200W+ card to max a videogame out.

the quad sli (4x) Titan rig i use for work averages 1.2-1.3kw draw on gpus alone when being used properly lol

I don't think it's a good development though. If you take the huge jump in power consumption in to the equation the GPU industry hasn't really advanced that much in computing power the last 5 years.

As an example, an HD3850 card uses about 60w max, a HD7990 uses over 350W. That means you could run 6 HD3850 with the same power consumption as one(dual gpu) HD7990.

6x HD3850= 6x 427 GFLOPS= 2562 GFLOPS (that's close to an HD7950)

1x HD7990= 2x 3788,8 GFLOPS= 7577,6 GFLOPS

So that's less than 3 times the computing performance in 5 1/2 years, or just over 20% a year. The rest is simply due to letting the chip draw more power.
