GFX Card Question #2

[Scott88]

Another question for you guys
When it comes to GFX cards, I ain't very sure.
Just want some peoples thoughts on what the best card to buy would be out of the following. Proposing a budget of around £400-£460, which is the range of the following cards.

Basically for a system of the following;
- Power Supply: OCZ ZS 650w PSU / Something smiliar, 550W minimum.
- CPU: Intel Core i5 2500K 3.30GHz Overclocked to 4.60GHz Sandybridge CPU
- Motherboard: Gigabyte Z68X-UD5 Intel Z68 (Socket 1155) DDR3 Motherboard
- RAM: 8GB DDR3 1600MHz Dual Channel Kit.
Running 1650 res on 22" monitor. (I do plan to upgrade the monitor in future for a higher resolution).

Cards to consider;
EVGA GeForce GTX 560Ti 2048MB GDDR5

Running 2x SLI.

HIS ATI Radeon HD 6950 IceQ X Turbo 2048MB GDDR5
http://www.overclockers.co.uk/showproduct.php?prodid=GX-036-HS
Running 2x Xfire.

HIS ATI Radeon HD 6970 IceQ Turbo 2048MB GDDR5
http://www.overclockers.co.uk/showproduct.php?prodid=GX-038-HS&groupid=701&catid=56&subcat=1752
Running alone.
EVGA GeForce GTX 580 SuperClocked w/Backplate 1536MB GDDR5
http://www.overclockers.co.uk/showproduct.php?prodid=GX-149-EA&groupid=701&catid=1914&subcat=1812
Running alone. Various of these cards, i'm not sure what would be the best.

XFX ATI Radeon HD 7970 3072MB GDDR5
http://www.overclockers.co.uk/showproduct.php?prodid=GX-206-XF&groupid=701&catid=56&subcat=938
Running alone. Again, various types of these cards, not sure what specific card would be the best option.

What would you guys choose? And why?
Like I said, I really don't know what would be the best option.
Also, would the motherboard selected support the above options? Or would it require upgrading? I.e for 2x cards maybe?
And the PSU, I think 650 might be a tad tight, so perhaps 750 would be an ideal minimum?

Any thoughts would be greatly appreciated.

Thanks

I'm edging to the 7970 with a high budget like that. However it might be best to wait for the 31st Jan as the 7950 is rumoured to be released on that date and should be much better for money compared to the 7970.

If i had the spare cash to throw away id crossfire, simply due to the fact it looks better in a windowed rig, but since I dont have cash to throw away I simply cant justify anything higher then a single 6950/6970 for the res you play at. I play the same res adn in BF3 on max settings i play at around 70 fps never lower then 40 in heavy battles and the fps drop isnt even noticable and if I had a I5-2500K it would be even better.

So personally Id do as I said above. if i had the cash though id sli or xfire but purely for cosmetic purposes since you will have major over kill unless you have a high res/multi monitor setup.
