Corsair Enthusiast Series TX 750 Watt ATX (TX750M)
Sapphire Radeon HD7970 3GB DDR5
16GB Corsair Vengeance Blue DDR3 1600 Mhz
Samsung 840 Series 2.5 inch 120 GB SATA III SSD (MZ-7TD120BW)

I've been running this system for going on 6 years now. I mainly play games like Diablo 3, WOW, Overwatch, etc. If you had $1,000 to spend, what would you suggest I upgrade?
