This was a $800 dollar AMD build. This was my dad's and my first build. We chose the FX-6300 ($120 on newegg with a free game) and a GTX 650 TI Boost (Best Buy had it for $150). I got a great case, the Rosewill Redbone U3. We also got the semi-modular Corsair CX-600M 600W for $60 on Newegg. I got the ram, mobo, cooler, and OS on Newegg. I got my optical drive and hard drive at BestBuy. Installation was smooth. I did have a bit of trouble with the case and the mobo. It took me and my dad forever to find where the power, reset, and all the other case cords plugged into the mobo. I would definitely recommend all the parts I used to other people.
