Gigabyte GTX 670 OC (2GB) vs Sapphire Radeon HD 7970 OC (3GB)

[alexander aird]

Hi guys,

I'm looking to build a pc, and I've decided on everything bar the graphics card.

Current (core) specs:

Case: Sharkoon T28
PSU: Antec HCG-750 750W High Current Gamer 80PLUS 135mmfan
Motherboard: Gigabyte GA-Z77X-D3H, Intel Z77 Chipset, Socket 1155, 7.1 CH
CPU: Intel Core i5 3570K LGA1155 CPU 3.4Ghz 6Mb Cache Ivy Bridge
RAM: Kingston 8G(2x4G) DDR3 1600MHz CL9 HyperX


Now, I'm looking at either:
Sapphire ATI HD 7970 OC EDITION V2, 3GB
(AU$399.00 where I am, http://www.umart.com.au/pro/products_listnew.phtml?id=10&id2=1391&&bid=2&sid=105439)

OR:


Gigabyte GTX 670 OC 2 GB
(AU$419.00 where I am, http://www.umart.com.au/newindex2.phtml?bid=2)

I'm not actually too worried about the price, either-or suits me.

Which would work best?

I'd be looking at playing games like Fallout: New Vegas (with many, many mods), Skyrim (Also with many, many mods), Crysis 3 and ARMA III, when it comes out.

Which option would be best, and should I change any of my other components?

Get the 7970 OC, not only is it cheaper but is faster than the 670 and can OC higher and has more VRAM
