I never put much faith in benchmarks, I have had machines get great benchmarks but play games crappy while other computers got poor benchmarks but played games great...si I see benchmarks more of a tool for bgragging rights. I do like the full version of Fraps http://www.fraps.com/
I have the pay version and you can do some cool things that ya cant do with the free version, plus once you buy it you always get free updates to the newer version......so I use Fraps and will scan my computer with the performance utility at www.pcpitstop.com
but lately they are getting more commercial and trying to peddle software to improve performance...I have found CC cleaner to be a decent free utility also http://www.ccleaner.com/
just be sure you look at what it finds in the registry and when it asks you if you want to back up the registry click yes.....you can screw up your machine if your not carefull when it comes to the registry...
