Well this is the newest bios from ATI (recived it three hours ago) I sent in a complaint to ati about the card artifacting and the tec just sent me this link, so all you XOC owners try this one.
this a direct copy and past of the email i recived from ati tec center.

"Here is your new bios for HD4870OCX-512MBs at 795MHz-1100MHz and Clock Limitation is 990MHz-1250MHz. Also, this bin has been modified the voltage’s setting as well so it should be fixed on artifacts issue for certain motherboards. I ran a test via 3DMarks 06 for more than 2 hours with the new bin and did not see any artifacts related.
