I'm having a problem with my HD 5970.
I've noticed this in game and when running stability tests. My gpu usage dips from 95%+ to 70%. This is both with AND without overclocking.
System specs.
CPU: Q6600 @ 3.5ghz
850 watt PSU
4gb ram
Sapphire HD 5970 (currently OC'd putting 1.72 volts into it, but the fluctuation happens with no OC).
Gigabyte EP45-UD3P mobo (with pci-e 2.0 @ x16)
Old-ass SATA hard drive @7200, apparently I've gotten lower than comparable results in HD tests, but I don't know if that relates to this problem specifically.
Interestingly enough, when using Furmark, my GPU usage fluctuates consistently (not temperature related as far as I can tell), but when I run the stability test in "extreme burning" mode the GPU's do not fluctuate and remain consistently above 95%.
Also, games like bad company 2 and crysis still run like crap, like 30fps! It seems like I'm not getting the most out of my card.
Oh and I have the latest 10.6 drivers (and I've done the driver sweeper stuff as well).
Can someone explain to me what's going on?
What should I do about it?
What should my next upgrade be to maximize my 5970 (there might be a serious bottleneck somewhere)?
