Help yourself to the free tools below that we use (amongst others) to benchmark, test and score the performance of PC's. In most cases these are links to the authoritative download site.
HDTach - benchmarks disk IO and seek time performance.
HDTune - as with HDTach but has a different presentation preference between the two tools is usually personal. Both compliment each other quite well.
Prime95 - Calculates Mersenne prime numbers ultimately to discover new Prime numbers (using a GRID computing model).
nTune and nVidia monitor - nVidia's own tools for tuning and monitoring their chipset and graphics cards. The monitor tool is poor on non nVidia chipset boards, and isnt really the best even on nVidias own boards. Generally
RivaTuner - a better tool for tuning graphics card performance with the bonus it also works well with ATI GPU's.
Asus ProbeII - good monitoring tool from Asus for their boards. Also works on many other manufacturers boards.
nVidia driver wizard - for chipset and graphics card driver updates. Check this regularly and download WHQL approved drivers only. Beta drivers should generally be avoided they will likely have some stability issues.
eVGA - for BIOS and tools updates
Gigabyte - for BIOS and tools updates
Asus - for BIOS and tools updates
Abit - for BIOS and tools updates
FamFamFam Icons - for neat little free website icons
