I have recently just built my first build and want to know the best option for a video card.

Mere's My specs:

-Intel Core i5-3570K Ivy Bridge 3.4GHz (3.99GHz Turbo OC) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000
-G.SKILL Ripjaws X Series 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
-ASUS P8H77-V LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
-CORSAIR CX Series CX750 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply
-PowerColor AX4870X2 2GBD5-H Radeon HD 4870 X2 2GB 512-bit (RUNNING CROSSFIRE)

The Video Cards came free from a friend and run amazingly. They're outdate but run games like a boss still. They can be quite loud though. I am debating between keeping the Cards or selling them to buy 2 HD 7770's and running crossfire. Can anyone tell me benchmarks or comparisons of the two.

I am not sure about the performance but I have been running 2 5850s for a while and have no problem with maxing out graphics.
