Lagged games after rebuild.

Recently after purchasing a new case/power supply and doubling my ram, I have run into some problems with Quake 3. After rebuilding into my new case, I began to hear a strange noise, which I thought was the fan on my gpu. After this started, Quake 3 seems to skip frames and simply does not run as smoothly. I jumped to conclusions a bit to quick and replaced my gfx card with a 8800 gts, but I'm still having the same problem. Here are my specs:

Asus M2N Motherboard
AMD 5200+ 2.6ghz dual core
2GB ram (before rebuild) 4GB ram (after rebuild)
evga nvidia 7900gs (before rebuild) evga nvidia 8800gts (after rebuild)
Antec NeoPower 650 650W ATX12V (after rebuild)

Oddly enough, whatever is causing this lag doesn't seem to affect the FPS I get in-game. If I turn off the FPS cap, I get a steady 700FPS. I've had the same problems on Arch 32/64 and Ubuntu 32/64.

I should also point out that the noise I hear only happens in-game. I also heard this noise on a web page using flash, specifically when flash was used to blend one image into another. While the noise is less apparent after changing video cards, I still hear it occasionally.

Any suggestions on what might be causing this lag or any tests I can run to figure it out would be great.

EDIT: The FPS does in fact drop briefly when the game lags.

I'm starting to think the problem may be with my hard drive, but I can't be certain. The more I watch the FPS in Quake 3, I notice it drops every few seconds, but my overall average FPS is where it should be.

Hmm. I don't know how to figure your problem out directly, but perhaps try the Linux-Gamers livedvd or Sabayon livedvd and see if games related to quake 3 (like trem, warsow, open arena) have the same issue

That will knock your hard drive out of the picture if they work fine. There is also a memtest86 on them i think.. Two birds with one stone.

I have the same problem when playing these games using a live cd.

Next is a Memtest.

EDIT: Memtest was fine.

So I now know it is not the hard drive or memory.

Whats left is the CPU, the gfx card and my motherboard. Any suggested tools for testing these?

EDIT #2: I ran glxgears, and when fullscreened the gears noticeably "skip". Here is the output, not that it has much useful info:

42084 frames in 5.0 seconds = 8406.283 FPS
41918 frames in 5.0 seconds = 8374.288 FPS
41382 frames in 5.0 seconds = 8272.180 FPS
41650 frames in 5.0 seconds = 8323.735 FPS
41582 frames in 5.0 seconds = 8300.653 FPS
41561 frames in 5.0 seconds = 8302.409 FPS
26164 frames in 5.0 seconds = 5213.594 FPS
9271 frames in 5.0 seconds = 1854.175 FPS
9306 frames in 5.0 seconds = 1861.137 FPS
9237 frames in 5.0 seconds = 1847.315 FPS
