Buying Geforce GTX 680ti

[Arviko]

Going to buy a new Graphics card. My components are: Intel Core i5 3570K 3.4 GHz (Ivy Bridge), AsRock Z77 Extreme4 Motherboard, Corsair TX650V2 Enthusiast Series 650W TX ATX/EPS 80 PLUS Bronze PSU.
I'm using 2 monitors where the best one is: ASUS VE247H 24 inch LED Widescreen Full HD 1080p Support with HDMI 2ms Response Time Splendid? Video Intelligence Technology


Since I'm going to order the GPU here's the alternatives for me:

MSI GeForce GTX 780 Ti 3GB = 875 dollars
Asus GeForce GTX780TI-3GD5 3GB = 875 dollars
EVGA GeForce GTX 780 Ti HDMI DisplayPort Dual-DVI 3GB = 875 dollars
Gainward GeForce GTX 780 Ti HDMI DisplayPort Dual-DVI 3GB = 875 dollars
Gigabyte GeForce GTX 780 Ti Windforce HDMI DisplayPort Dual-DVI 3GB = 875 dollars

Any reason in particular why you want a 780Ti over a regular 780? You can get about 85-90% of the performance for ~60% of the cost, all while keeping the same amount of VRAM. If you're looking for a truly massive performance upgrade, consider getting 2x 780s and a PSU upgrade instead. For about $230 more than the price of one 780Ti, you'll get double the performance.
