Yep, replace the onboard video with your old ATI.. make sure it's compatible with that system.

And I read your specs wrong.. I read the clock speed, but didn't keep reading it's a amd 2200+.. that should be fine for P7.

They'll be harder to hunt down, but see if you can find some of the "hot" video cards released last christmas.. they'll be dirt cheap now, and will give you an excellent perfomance/price ratio.

Doesn't seem to matter much ATI vs Nvidia.. there are proponants in each camp, and there should be plenty of comparison reviews by now.

I'm guessing the onboard video is sucking your ram, and your system is using it's HD cache to fake ram, and slowing your system down a lot in the process, since it's "ram starved".

Turning DOWN the opengl video preview resolution might also help take that burden off as well, but then of course you are turning off some of the new features you just paid to upgrade to.

Way too many people take way too many things way too seriously.
