This machine/build is used for gaming and music production. I work with Pro Tools and various other DAW software daily so the ram is meant more for quick rendering but nice for everything else none-the-less. I've uploaded a couple of benchmark screens: I've left everything pretty stock and given its performance so far I don't have much interest in messing with things. I'm well aware it's only recognizing 36GB of the 48GB of RAM installed. I'm not sure why, and I haven't had the time to trouble-shoot it. 36 is getting the job done nicely for the moment. (Yes, I run Windows 7 Pro before anyone asks or suggests anything.) I included the WD 300GB bench if you want a good laugh. That's an old sata II model Raptor drive but it gets its job done very nicely; it's job being: hold highly important backup files in case things go awry.
I plan on adding a few more upgrades this winter and right now those look like it may be:
2 way SLI - 2xAsus GTX 760 - (http://pcpartpicker.com/part/asus-video-card-gtx760dc2oc2gd5)
