it's probably AMD pushing for Intel to step up their integrated graphics game. I was actually pretty surprised to find how well my 4690k's integrated graphics handled TF2 a while back.
while I'm here I'll mention the laptop my uncle gave me after he pulled it out of the dumpster. it's some dell ultrabook with a 2.6ghz fifth gen i7, 16gb ram, and a 250gb ssd. screen is busted but that's the only thing wrong with it. gonna replace the screen some day.
