Any of you guys with Nvidia 6800 (standard, GT or Ultras) cards have problems with stuttering or 5-10 secdond pausing during gameplay. I have had a few isssues where it looks like the computer has wiped out (frozen) and then about 5 seconds later it comes back running as normal and doesn’t do it again. Also had this problem when benchmarking with 3dmark2005. I’m wondering if it is a driver thing...but looks like threre can be many things that cause this.

I'm using

BFG 6800 Ultra (with 71.20 drivers at present)
MSI K8N Neo2 Plat (NForce 3)
AMD 64 3500 OC'd
550W Levicom

My GPU temps seem to be OK…running at 50-53 idle…and case is sufficiently cooled. I have OC'd to 450, 1.17.
