Just "defected" to AMD after being an NVidia loyalist up to this point - switching from GF460 to Radeon 7970 (XFX's Double Dissipation Black edition), and I've got a pair of questions:
1. The 7970's instructions recommended using two distinct outputs from the PSU. I misread this to mean that a plug (modular PSU) with two PCIe connections on it was okay. I'm having some stability issues (Medal of Honor: Warfighter crashes after a max of 10-15 minutes with with BSOD, Hitman Absolution after about an hour although I've had longer) so I'm wondering if putting in a separate PCIe feed from the PSU would correct these? (PSU is Corsair AX750 Gold - so I should have plenty of power).
2. XFX's software bundle consists solely of the AMD Catalyst Control Centre. Is there any tool (other than GPU-Z which I'm using at the moment) that I can use to monitor/control fan temps and speeds? I'm not bothered too much about oc'ing the card at the moment (because it's already oc'd) but being able to bump up the default fan level in "auto" mode would be nice.
By the way, I had some "fun" with XFX's default driver install - with some games (esp MoH:WF) claiming that I didn't have the required DX10 level present! I managed to solve that by overwriting the XFX-installed version with one downloaded directly from AMD's site (which reported as being as the same version as I'd just overwritten).

That said, a bit of further research seems to show that MoH:WF isn't exactly a model of stability even with proven good setups. I'll maybe dig out BF3 or FarCry3 and see whether they've got the same issues. Hitman's maxed out for graphics, and someone's just reminded me that the weather at the time I was "testing"
