looking at those pics, the question thisnameistaken should be asking is "do I play Star Craft?"
in some scenarios, a skoda will out perform a ferrari (ice racing). that doesn't mean the ferrari is shit does it?
Don't worry, I saw some benchmarks. The price depends on the region, I could definitely save a few bucks by getting a Bulldozer system here(the MoBo's for Bulldozers come cheaper too, at least here). I admit wouldn't be much, but in the end you still need a high-end GPU to be able to tell the difference between i5-2500 and FX-8150 in most games, who cares if a game runs at avg 180 or 120 FPS?
I'm not going to honor this flamewar any further, but unless that power benchmark was run at 4 threads only, it's completely meaningless. 8-core CPU will always use more power than a 4-core one under full load. Also the idle power consumption get better when you use an OS with Bulldozer-aware CPU scheduler which lets the whole module "park".
