Summary: I debated between this and the A10-5700k (100w vs 65w) but considering reviews which showed that during load they end up with the same draw and temps. I went with the A10-5800k as i don't leave my HTPC on all the time anyways. The included heatsink was tiny! I was skeptical at first but it does the job. It peaked around 51c with 3hrs under load and case temps at 39c which i thought was pretty good. I'm sure it could be better but given how silent it runs i'm impressed.
Pros: Great for HTPCs. At stock it can run League of Legends at 1080P max settings 62-71fps. Skyrim/Borderlands however was only smooth at 720p ultra settings, had to tinker to med/low settings on 1080P.
Cons: Not the best choice if you plan on getting a video card. Also, A85x UEFI bioses aren't HDTV friendly(depending on if your receiver/HDTV properly scales) so there are issues where the bios screen would not show up on a HDTV; easily solved by using a dvi/vga monitor. It looked like it didn' boot at first.
Summary: I guess I have to say I've been using AMDs at home for fifteen years and never burned out a cpu (lots of other stuff, but not a cpu) so I figure why change. I have on my machine at work an I7 2500 which sells for $350 and the 3dMark11 score on this machine is 300. That's right, 300. This thing outscores it even before you put in a graphics card.
Pros: In Win8 this cpu seems to set itself by default to 4.3 Ghz. With no graphics card, by itself, it will get 1500 on 3dMark11. With HD 6670 in cross fire mode it scores 2560. If I overclock using ASUS software the 3dMark11 score goes down, so maybe not doing something right. Put it on an ASUS F2 A85 V Pro. You really want to go top end on the mobo so you have all the ports that make chip a flexible option for home theater. Don't scrimp on the mobo you won't regret it. Al...
Cons: I guess if you want to do well on benchmarks you're going to want to pop $500 or more on the best CPU and best RAM. I'm using the Radeon 1600 RAM (16 gigs). Win8 experience index score of current build is 7.0. To get higher on the benchmarks you have to throw a lot of money at the RAM and the CPU, near as I can tell, and overclock on top of it.
