So here's the specs of my computer

Intel Core i5-760 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Desktop Processor

G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600

BIOSTAR T5 XE CFX-SLI LGA 1156 Intel P55 ATX Intel Motherboard

EVGA 012-P3-1472-AR GeForce GTX 470 (Fermi) SuperClocked 1280MB 320-bit GDDR5 PCI Express 2.0 x16

All powered by a CORSAIR CMPSU-750TX 750W

My PSU also runs 4 fans on my Antec 900 Case , a CM V8 CPU Cooler , and my HDD .


These are all stock speeds (except for the GPU, it comes "superclocked" already).

My question is, if I want to add a second GTX 470, will my Corsair 750W PSU be able to supply enough energy?

If it does, will it be limited by my CPU or RAM?

My monitor, I play at 1920 x 1080. Mostly used for gaming.

For ~$270 money isn't much of a problem at all to just buy 1 more GPU. If I need to upgrade some other parts of my computer then I'll probably just stick to 1 GPU.
