The scores were a little higher for the ES card with the second set of drivers but nothing record-braking.
Core temp idle was 58C, core temp load around 86-90C, which was good.
It's laud, but not 5800Ultra.
In the tesselation tests, the GTX-ul won with +53% vs 5870, but this is as relevant as the 5-point parallelism issue where the The tesselation performance wasRAdeon wins with 350%+.
Idle power is at least 3 times that of the 5870 and the drained power at load was 283W. The official 480 will have less drained power because it will have a whole shader cluster disabled.
