Just wondering if anyone is running this combination and what your benchmarks are. I upgraded from a 4850 and there doesn't seem to be much of a difference in performance. My 3dmark 06 score is around 10500. That seems to be kind of slow for that card. Only a few more hundred than my 4850. My system is a new build. I'm thinking my psu is not up to par. Its a Thermaltake TR2 RX W0134RU 550W ATX12V Ver2.2 NVIDIA SLI Modular Cabling Passive PFC PFC Power Supply - Retail. My system randomly locks up after startup once in a while. I did a fresh windows intall with XP Pro. My M.b. is Gigabyte GA-M57sli-s4. It does not have pci express 2. I run everything on 22" monitor maxed out- 1680x1050. I ony have to games intalled at this time. Crysis running at high settings it get an average of 30.573 fps. my low fps is 6- using Fraps. I don't get that. She bogs down in explosions our alot of intense action. Oblivion is my other game and I get stuttering quite a bit. I have 2 gig of pc2 6400 Kingston ram. I tried different catalyst versions as well as the current 8.8. and I still have the same issues. I'm hoping it's just the psu and I will just switch that out with a better one. Also, my athlon x2 6000 does not want to overclock at all which seems strange even with stock cooling. My case is a RAIDMAX SMILODON ATX-612WB Black 1.0mm SECC Steel ATX Mid Tower Foldout MB Computer Case. There's plenty of cooling in that case. GPU idles at 50 with fan fix. CPU idles around 45 with stock cooling.
