I did something a bit odd for my desktop, since I wanted a media system more than a gaming monster. It's a year old and is currently running an Apache on a Linux VM to host a website, among other things that've gone far beyond its original design brief. It'll even play Crysis. Well, Crysis 2. The A10 has really impressed me, - better than a crippled Intel and a budget graphics card anyway - and I'm curious to see what happens with the next the next FM2+ products
Fast RAM and an APU go well together. Even if the 7850k wasn't available when I built it.
APU: AMD A10-7700k
Motherboard.: MSI A88xm-E45
RAM: 8GB Kingston Hyper-X 2400Mhz
Cooler: Something that works
PSU: Corsair CX600M Modular
SSD: 128GH Samsung 240Evo
HDD: 1x320GB + 1x1TB salvaged from 'somewhere'
Case: Fractale Design 1000 USB3
It's got basically 500 days of contant running on it. And only the ten year old HDD has ever given issues.
