Look, we are CHEERING for you, AMD, but you often dissapointing us rather than not.
Looking back, we don't have much choices for GPU with open source driver in linux land. But now, Intel's increasing their pace, and we have HD4000, good enough for light gaming/3D/etc. Plus their driver is very good comparing to the rest. Like @allquixotic said, it comparable to #1 AMD card from 2 year ago, in open source area. When haswell is out, well, let's see what will happen then.
