It has done a very good job running my dad's pc

from completed build Sub $240 Quality AMD Build

This is a great APU for an HTPC or budget build. It runs Windows fantastically, and I've found that Counter Strike Source, and Hawken run great on it. I've gotten Battlefield 3 to run on it, but being that Battlefield 3 is optimized for a quad core CPU, this dual core APU had a little trouble with sound and stutters. Don't expect to run AAA games on it, but do expect a smooth performing APU, and smooth 1920x1080 video playback.

Pretty much what you'd expect from a dual-core, with the added bonus of an integrated GPU. Performance with the iGPU and dual graphics are great. I had some issues with stuttering, but was fixed by turning off Frame Pacing in the CCC. There was also Ubuntu (infinite restart loop issue), according to their forums it was the APU, either way I've since switched to Windows 8.1 and have had no problems.

from completed build Budget AMD Build

It's cheap and has decent graphics. Up to now I've used a Haswell Pentium and it's served me well. The only area where it occasionally stumbled was graphics, however the various reviews indicate that this baby should be slightly better in that respect.

I got this CPU for $40 in 2012, it is very capable for Linux and it is unlocked.
