AutoCAD and gaming. It works great! It's extremely fast and it can run games like Battlefield 3 on 1920x1080p completely maxed settings at 60 fps. I got the Ram for free with the motherboard, the OS free from my school, and I reused my HDD and optical drive. In total I spent around $800 on the tower itself.
Update: I added an H80i and a additional fans and filters. I also sold my HD 7950 for 120% value, because of Litecoin miners, and I bought an MSI GTX 780 LIGHTNING
