Hey, I've got a q9650 o/c to 4Ghz, 8gb ram, on an X38 board.... Running 1680x1050 res in Windows 7 64bit. Just upgraded from 4890 CF to a single 5870, and I'm experiencing strange graphical problems in 3dMark Vantage... frame rates all seem good, and in other games where I've tried dx9, 10, and 10.1 stuff, it all seems to run just fine, also 2d is just fine as well. I'm now running the beta drivers, but had the same problem with the 9.9's off the CD that came with the card. Never had a problem with the 4890s so I'm a little dismayed, I've attached a screenshot, and you can see black triangles in the water, and strange textures on the cave wall in the Jane Nash test, which all seem to flicker randomly when running the test. Can anyone shed any light on this??
