Well I received my PC (thanks Philip and Chris for sorting that out). I have now installed everything but I am getting shocking framerates in games with the GTX 470.
It's really laggy and is between 15 and 40 fps.
I've read websites that say I should be getting about 60 - 80 with my rig but it's nowhere near that..
I've got i7 930 @ 4.0ghz, 6bg of Corsair ram, ssd 64gb, 500gb f3 backup drive, 550w corsair psu, 22" Iiyama screen.
I've installed all the latest drivers, installed about 4 different graphics drivers (clean installs in safe mode). I can't improve it. GPU temp is only running at 48c - 60c.
Any ideas?
