I use this build for gaming, and running a Minecraft Server. I have 2 monitors, although the second one isn't included in this build because it was another unused one that I had laying around. It runs any game that I throw at it, even Skyrim with HD textures on Ultra settings, at around 40-50FPS. I've never had any problems with it, except that one of the PCI ports it fried or something, so that I cannot use it to SLI or CrossFire, but that's ok because I was never planning on using SLI or CrossFire. Everything works fine and is very good and comfortable. I haven't needed to overclock the CPU or GPU, and the only thing I've upgraded is RAM (When I first built it back in May 2012 I had 8GB RAM, recently I've bought 8 more to help cope with my Minecraft Server). When I bought it it was $1035, and then I recently bought 8GB RAM at $45, so in total I've spent $1080 on it.
This computer handle anything and everything, but not always at the highest settings ;) It was a budget build, but a very good one at that. I shopped right and got discounts and everything went well. The only thing was that it took a bit for the parts to arrive, longer than they said it would take, and I got a bit impatient (It was my first build, and I was excited for it). Since then I have built many other computers, none of them being my own or for myself. Soon I will be building another one for my parents, a very cheap one, too, and then another budget build for my Mechanics instructor. All in all, it is a very good computer, especially for the price.
