I am running an ASUS Nvidia 9800 GTX+ DK GPU at full everything no problems, this card is 4 years old, and some of you are having problems with newer cards with more memory and more stream processors. Sounds to me like your MOBO's are not up to the task.
FYI I will be upgrading to some of the newer cards perhaps an AMD ASUS Radion 6700 series.
I have a dell laptop E6400 with an NVidia NVS 160M Quadro, 256mb video card with 8 streams. I can run everything maxed except for shadows without any noticeable frame rate loss. Just throwing that out there.

is that you can't properly teabag your defeated opponent

I recently bought a new desktop, w/ nvidia 640 oem. It's not known to be a high end gpu, but I have all the settings maxed out. I either play it on 1080p in 2d or 720p in 3d. It handles star trek online pretty well, but I have no idea about other games.
