With that said, who the hell cares what it can do under windows I want to see this puppy unleashed with some nice optimization flags and unleashed in LINUX.... Of course, the driver problem seems to be holding that up.
Anywho, I think that even the anandtech results show promise - in terms of gpu performance, it takes Iris Pro (which is only really available on $250+ cpus) to keep up with any AMD part. For first generation Steamboxes, if AMD could ever get this thing working acceptably under radeon or Catalyst, it wouldn't even be close to go with the amd builds if you want to budget it around $200 - 300 without a discrete gpu. And then you also have to consider, how many really demanding games are there under Linux besides Metro? Most of what you'd play locally would run at 1080p/60 just fine on a top end Kaveri assuming Linux performance near parity with the Windows. Though I guess thats asking a lot.
