Well for now, R9 270X performance/stability with the opensource driver is a mixed bag. With glamor enabled, 2D performance is bad, without color tiling enabled things are prone to breakage, but 3D performance is top notch. On the other hand, with EXA enabled, 2D performance is excellent, but 3D performance is crap. Even though there arent many commits since the last stable release of xf86-video-ati ddx driver (comparing to xf86-video-intel where Chris is spitting out code like crazy and all the work he invested in SNA acceleration developement) - I'm pretty satisfied with the maturity of the ati/radeon driver, even though this is a (re)brand(ed) new card, things pretty much work OTB.
With some time invested in testing, things could be even better.
First of not so many I hope...
/edit: Oh, and this was a replacement for a GTX460 that was fscked during RMA process (one of the fans were noisy), all things considering I did benefit from the service guys screwup.
