[Below is a copy of a post i made yesterday on tomshardware, but i have not gotten an answer and this is urgent, so please excuse the repost on another website.]
Here's my build:

There are two of those r9 280x cards in the system, and I have them crossfired.
So, I bought and built this new PC (my first build from the ground up, by the way), and all was and still is running alright, but I began getting minor artifact issues is a few games, particularly Warframe, BF3, and Planetside 2 thus far (with vsync on in planetside 2 if that matters). I am wondering what is causing the artifacting. For the record this artifacting (and any other glitching) has NOT occured in the following games: Mabinogi, Crysis 2, Dead Space 1 and 3, Left 4 Dead 1 and 2, Garry's Mod, and Path of Exile.
Things I have done:
*Un-crossfired and run each card seperately in BOTH pci-e 3.0 x16 slots, and both cards checked out as alright.
*Lowered the core clock on both cards to 850 MHz (down from 1070 stock overclocked). This did prove to make the cards a bit more stable seeming and less screen tearing occurred because of this, but the minor artifacting did still occasionally occur.
*Ran a 15-minute FurMark Benchmark on each card, of which both passed topping at ~82 C temp wise and no noted artifacting. (in case it is important, i will include that some odd and consistent screen tearing occured in FurMark with the clocks at 1070 Mhz, but not at 850 Mhz. This is true for both cards.)
Any thoughts? Is it just a driver issue because these are relatively new cards? Should I send something back for a replacement? Did I set something up wrong? Any help would be appreciated.

Could the crossfire bridges cause artifacting? They're both new bridges that came with the GPUs but hey, that'd be an easy fix if it were the issue.
