thats definitely abnormal, especially at that resolution. what I would recommend is to use gpu-z and do a test gpu stress run to see if your gpu changes from idle pci-e 1.0 x4 to whatever your land speed is(should be pci-e 3.0 at x16 under stress) after that i would monitor the clock rates and if neither work, I would instal drivers from scratch by manually uninstalling the AMD drivers and registry keys(there is a guide)
Sorry, typo 6950 2GB, 60 +/- with Phemon II x4 @ 3.4 all maxed except aa at medium. Sleeping
dogs & black ops 2 (single player)
Can't quite remember the other games, but all try to play at max settings expect AA med. XOMC was 60 max, but no surprise. Bordlands 2 jumped around a bit but with low physics got 60 except for the notorious water psysic.
btw, you do have most recent Sleepging Dogs update installed right? 1.5 or 1.7 i think?
P.S. I only time (reflected in your benchmark) that's you'll really see problems is in that house with the sum painting, 40% of games is cinematic, 50% is running aroud the streets, 10% is actually intensive. I ended up setting mine a bit higher than normal cause the high graphics parts are quite impressive, and becuase that 10% is so a far and few between, and can change it on fly, I didn't notice
