Graphics Card
XFX HD5870

AMD Catalyst Driver Version, and Driver History
Currently 13.3 Beta, have tried 13.1 and 12.6, using AMD Cleanup Utility between installations.

Operating System
Windows 7 64-bit SP1, fully updated

Issue Details
Games lately feel very choppy, despite registering 60 FPS and stable pings. Please see this video for my issue:

Motherboard or System Make & Model
ASUS P6X58D Premium

Power Supply

Corsair HX850W

Display Device(s) and Connection(s) Used
Samsung T220HD connected via HDMI

Applications and Games

I've seen the issue in TF2, Left 4 Dead 2, and Loadout so far.

CPU Details
i7 930 (HyperThreading enable) @ 2.8GHz (stock)

Motherboard BIOS Version
BIOS is currently the last available, 1501

System Memory Type & Amount
3x 2GB Mushkin Redline

Additional Hardware
Nothing remarkable (DVD burner, wi-fi dongle)

Additional Details

I've reinstalled Windows 7 twice

I've switched USB wi-fi adapters

I've ditched those and connected directly to the router

I've set everything to their lowest possible settings (apart from resolution) with no difference in performance

I've changed mouses and keyboards

I've tried a different video card (XFX HD 6770)

I've reset CMOS for lack of ideas

Temperatures all seem perfectly fine, and the system feels completely stable besides this performance issue.

I'm willing to attempt any horrible voodoo/diagnostic you folks might suggest, as I don't fancy having to RMA something, pay for shipping and get told there's no problem with it.

Thank you in advance and sorry if I've left out any pertinent details.

Some ideas:

Turn off vsync in the games

Turn off the Steam overlay

I'm afraid the issue is still present with those settings disabled, though I have to say if it did fix it I'd live with the stutter, the tearing I get in TF2 is absurdly bad.

Thank you for the suggestion though.
