utilities/websites to test a PC's speed

[jeeswg]

Does anyone have any recommended utilities/websites to test a PC's speed. E.g. to compare the performance of 2 PCs.

I would recommend to write an algorithm with fixed outcome. eg: add up all primes below 2,000/20,000/200,000/2,000,000.
You can go as high as you want, but I expect around 100,000 is enough.
Test the script on both PC, the faster PC will need less time.

It's also important to choose equivalent power plans before running the tests.

Nova is favoured in this review, the others look promising as well.

GPUCheck compare the performance of various games wrt cpu & gpu alone- a fair enough test if no OC.
