I'm not sure if my computer is compatible/ I have enough power supply.
To start, it's an Alienware R3 that I got as a gift about 2 years ago.
Here's the specs (if I miss anything, just google Alienware R3)
Processor: Intel Core i7-2600K (8MB Cache) Overclocked Turbo Boost to 3.9GHz
Power Supply: Alienware™ 875 Watt Multi-GPU Approved Power Supply
Ram: G.SKILL Ripjaws X Series 8GB x4 for 16 gigs (I upgraded it myself about 2 months ago)
Chipset: Intel® P67 Express Chipset w/ Unlocked BIOS for Overclocking, CPU Socket 1155
GPU: 2x Nvidia 460 GTX w/ SLI
Once again, it's a stock Alienware R3 so you can probably any tech specs you need on line.
