CPU mark composite average 45%+ lower than others

Make sure you are using the 64 bit version of PerformanceTest and not 32 bit.
Also make sure PT is using all 4 cores. Edit, Preferences and set processes to 4.

I've got a Core 2 Quad Q9400 at 2.66Ghz, stock settings (Asus P5N-D) on W7 Pro 64bit. After running the CPU tests and comparing it to 3 other Q9400s, I've noticed a huge difference in performance.

Results:
Integer Math, 506.6 vs. baselines of 1683+ (230%+ lower)
Floating Point math, 1991.7+ vs. baselines of 2589.3 (30%+ lower)
CPU Physics, 70.1 vs. baselines of 211.1+ (200%+ lower)
String Sorting, 1034.6 vs. baselines of 1700+ (65%+ lower)

I'm familiar with computer hardware, but I'm no pro. Everything appears to be properly installed. The heat sync is properly set and my core temperatures idle at 34C. I recently sent my motherboard in to Asus of diagnostics and they claimed that it passed all tests.

I should also note: modern games such as Bad Company 2 and CoD: Black Ops seem to perform very poorly somewhat regardless of my video settings, almost as if there is a bottleneck somewhere in my system. I know it's not the GPU because I've tried it out in other PCs with similar specs and they're getting double my FPS.

System specs:
Core 2 Quad Q9400 @ 2.66Ghz
Asus P5N-D
4gb DDR2 KVR RAM
Radeon HD 4770
Windows 7 Pro 64bit
