For those wondering about the maximum resolution they can run given OpenGL workloads at with the AMD Radeon R9 285 "Tonga", a new ~$250 USD graphics card, here's some Linux GPU scaling benchmarks with the Catalyst driver.

If you didn't see my review from Tuesday there's a complete review of the Radeon R9 285 Tonga under Linux as the first AMD GCN 1.2 GPU on the market using Catalyst -- since the open-source driver isn't yet compatible. Following that full 12-page review I ran some GPU scaling tests. If you're curious, here's those results.

The above mentioned setup was used for this round of testing. If you wish to see how your own system compares, install the Phoronix Test Suite on your Linux distribution then run phoronix-test-suite benchmark 1410152-LI-4KSCALING41. In this article the resolution scaling of the Radeon R9 285 on Ubuntu Linux is being looked at up to 4K UHD.
