i recently got a new rig
Newegg.com - Core i7-960/ASUS X58 Deluxe SuperCombo

set it up runs amazing, when i started testing out the video cards capabilities i noticed triangles and long lines, artifacts, on the screen.they got a little better once i updated the drivers but its pretty persistent.have not checked the temps but i doubt its the issue
settings are high, not maxed out.maxed out settings for crysis2 but artifacts are about the same.

i usually have to alt tab but the artifacts just reappear.
ill try and get a screenshot up soon
