I'm changing my graphics card and i want to run a comparision,
just to see if there are any improvements?

Any recommendation's ?

I'm sure i used a one called 3D Mark ?

3D Mark is utter shite! They completely lost their way when they changed from MadOnion to Futuremark. Its so theoretical and plauged with corruption too. The best benchmarking applications for 3D gaming are the games themselves.

Use SiSoft Sandra if you really want a benchmarking tool, it ownz, but its expensive.
