Since we are on the subject of micro-stutter problems, maybe you guys can give me some insight on mine. It looks kind of like this:

Except it's much less severe. The micro-stutter I deal with is kind of rhythmic and occurs about once every second. It's like the video is slowly getting "behind" and every second it syncs back up. I've noticed it in several games; Serious Sam HD, Madballs, WoW, and even VVVVVV. I've been dealing with it a while, and although it's annoying it's never been bad enough to make a game unplayable (though it did make VVVVVV even more difficult in parts). Updating drivers and toggling v-sync has not helped.
Specs:
C2D e8400
4 GB DDR2 RAM
AMD 4850 512 MB
P35 chipset
Win7 64
I'm at work right now so I don't have the complete details on my build.
I had favored nVidia for quite some time, but at the time I wanted to upgrade my card 2.5 years ago, the 4850 was by far the best bang for the buck. For a while I have considered this issue inherent to the card itself and as a result I'm feeling pulled back to nVidia when I upgrade again, but I thought I should get a second opinion from GAF. I'm planning on doing a lot more PC gaming this year so I've been looking at the GTX 460, but if I can get this problem resolved with the 4850 I might be more inclined to wait and upgrade more of my components later this year (and possibly stick with AMD).
Anyone have any input? Thanks.
