This has two major upgrades: An EVGA GTX 760 (replacing an ASUS GT-240) and an EVGA 850 B2 (replacing the stock Cooler Master PSU). It's used for gaming and music making. It is upgraded from what was a Hackintosh.
The GPU is AMAZING compared to what I had before, especially if you check out the benchmarks. I've loved playing Saints Row IV and Just Cause 2 at basically max settings with wonderful framerates. Other games have gained quite a bit of stability too.
The PSU helps a lot with looks, and I may get a different case soon that can do it more justice with it's cable management capabilities. It's also very quiet, and the Cooler Master PSU before it made a really annoying noise that was not okay for music creation. It also has a very nice capacity that makes me feel more safe with my powerful GPU.
