I've gotten my new system since yesterday:

i7 920
6 gig ocz ram
sapphire 4870x2 2 gig ram
900 watt tagan voeding
Gigabyte EX-58 UD5 mobo
2x 1 tb spinpoints (raid0)
2x 750 gb spinpoints (no raid, separate disks)
I run 2x 24" op 1920x1200, dual-view, vista 64 business

one of the artifacts screens I captured:

Theres a couple more 'variant's, like, little blocks spread accross my screen, and if i move they flicker.


This is however not the only issue.
Apparantly this card will always run in 2d clockspeed unelss ur in fullscreen mode. So i'm stuck with 507/500 clocks instead of 750/900.
I've been messing around with it all day now, and can't figure out where those damn artifacts come from. When I change settings in the CCC sometimes they disappear, sometimes theres more, sometimes theres less.. it's driving me nuts.
I have seen many threads of people with the crashing issues (that i had in the start as well, but got fixed when I turned off aero) but not any with artifacts.

I'm prety sure the card is not too hot, as its 90-100 degrees stressed, and the fan isn't even at 30% speed yet (auto control). Also turned manual fan control on once to test, 100% speed, temps went down 20 degrees or so but I still had the artifacts.

RMA the card and get me something else or has anyone got any advise on what to do?
