Gaming rig, runs most everything on high and runs cool.
Edit: - Also used for circuit analysis, CAD/FEA and occasional video/photo editing using Photoshop and Premiere Pro. - Was given a 660 when I started this build which is why there are 2 660s instead of a 770. - Slowly bought all the parts over a course of a few months, I just graduated from college. - The RAM is a bit of an overkill but I got it to make sure that all the processor/memory intensive tasks also perform well. - The second picture is missing just the second 660 (in-progress).
