Hey guys I picked up a 2900 Pro and added it to the rig in my sig crossfire with the 2900xt. I ran 3DMark06 and got 19517 3DMarks http://service.futuremark.com/compare?3dm06=4959749 with both cards over clocked in CCC. The 2900xt is water cooled the pro is running stock air cooling. Question is will I benefit much by flashing the pro to an xt, and is it worth the money to get a x38 board?
