This build is the result of hording computer parts for years. Which is why this thing has a 1000W power supply. It's just what I had. I only needed some RAM to build a complete system.
It is mostly going to be used as a home theater system and for some nostalgic gaming. For those few times a year when I need to run through Diablo II real quick or face down Kefka once more. I was able to play Dragon Age Inquisition at 1080p on low/medium settings but I don't think I'll be installing The Witcher 3. I ran some benchmarks and found the the APU by itself actually got better scores than the R7 250 when not running in dual graphics mode. But when dual graphics were enabled, I actually more than doubled either benchmark. So dual graphics works pretty well.
Speaking of the R7 250, It's a super cheesy card. The fan isn't centered on the heatsink and the plastic shroud is complete with fake screw heads. It works well though and I've given it the little overclock it will take.
I let the Asus software overclock the processor and it took it up to 4.3Ghz. That's a nice boost without having to do any work. The processor didn't seem to want to go up to its 4.0Ghz turbo speed but with the overclock it has no problem staying at 4.3 all day long. The low temps the A10 runs put me in somewhat unfamiliar territory as my other rig has an overclocked FX 9370.
I really like this build and it is probably a little overkill for what I am going to be doing with it. I was pleasantly surprised by how capable it turned out to be.
