Good news!!
Max TDP is **only** 250W instead of the 285-300W we all feared! YAY!!

Bad news!!
Totaly system power in Furmark is 480W (GTX 480 - coincidence): higher than 5970. Wow, thatsa hot meata-ball.

From techpower, on the "performance per watt" and "performance per dollar", only GTX295 is worse than the 480.. ouch.
Performance is very good in Heaven, and some DX11 games, but even with 5870 (or bit slower) in everything else. Good card for the future... when the future gets here.

But, amazingly, you can overclock it to 770-830Mhz (with stock voltage and cooling). Wholy mozes batman.
