Sapphire is supposed to be the better cooler, but either will be fine, the Sapphires also a ref PCB, and doesn't have Uber or Quiet modes, the BIOS switch just switches between Legacy and UEFI, the Asus though, has the Uber and Quiet modes, and is also a custom PCB like the MSi gaming (which also has Uber and Quiet), which also looks a cracker, so theres another one to consider, but tbh, i doubt you'ld go wrong with any of em Ive caved and decided to try the Tri-X as my mate can get them in (should be sometime next week), so thought worth a shot, as i can easily take it back without a prob, as was going to originally get the Tri-X, but then i decided to wait for the 20nm, but when hearing that could still be a bit away, i was considering just grabbing a 780.
Hmmm makes me a little uneasy. I was planning on getting 2 of these Asus cards. Now I may have to keep waiting. I am starting to get a little impatient. My rig has been in pieces for too long.
