A bit more than what you were looking for but some suggestions none the less -->
Extreme testing for the video card -->
http://www.ozone3d.net/benchmarks/fur/ called FurMark, run in Stability Test Mode, using the Xtreme Burning Mode options enabled, at 1024x768, windowed (uncheck fullscreen if it's checked), run with 16X MSAA, and make sure post processing is disabled, then hit go, and make sure to watch those Graphics card temps in something like your Catalyst Control Center.
Extreme stability test for CPU -->
http://www.wprime.net/Download/wPrime203.zip , then once DL'd, run the 1024M test, whilst monitoring temps in RealTemp

CPU-Z Good overview of generalised CPU information, eg like what your overclocking has done to the ram speed, front side bus (fsb) etc

Those are the main ones I can really think of that you'll need, also things like OCCT aren't too bad and if WPRIME isn't enough for CPU stressing you can also try Super-Pi Mod -->
http://www.techpowerup.com/downloads/366/Super_PI_Mod_v1.5.html , using the 32M testing option and Burn-In test of course, a good ol' classic.
For benchmarking with a score at the end solely for CPU's I'd recommend one called Geekbench -->
