lol, this is just for fun, its a very fast(less than 60 seconds), not too accurate, 3dmark benchmark.
you download nothing to your pc, just click the link
click on any 200 series or 9000 series card, and then look to the right of the page and you will see the benchmark
looks like this
we are looking for the current score it gives you and not the upgraded score it would be if you were to grab a new card.
just to help out, post your gpu-z and cpu-z if you can along with it.
here is my score lol
i dont think overclocking helps out too much
