Hoping for advice on whether or not to upgrade GPU or other parts of system..

Hi guys

I currently have:
i7 [email protected]
Gigabyte GA-EX58-UD3R (1366)
Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 1600MHz
2 x 1GB Sapphire ATI Radeon HD 5870

I play games quite a lot but currently have a 3D monitor which doesnt have the best resolution. Playing most new games on a fairly high settings. I have noticed recently I have to turn down settings more often and I find having crossfired sometimes ends up giving me some problems.
I guess my point is would it be worth upgrading to a graphics card like this with my current rig
-Gigabyte GeForce GTX 670 Windforce 3X 2048MB GDDR5 PCI-Express Graphics ~£320 or even one around the £210-250 range

Or is the build quite dated and i would be better buying new mobo etc (not PSU or storage) but keeping the 5870's and getting new card at a later date.

Thanks for any help

Thanks for the quick help

So that card would out perform 2x5870? Also yeah i bought that cpu with the intention of overclocking but never bothered buying a decent cpu cooler so i guess i could use the cash saved for one. Any recommendations?

Ooops i forgot to say i had an SSD already
