Dual Nvidia or Single?

I just built up a new rig and am trying to decide on my GPU. I remember this use to be so much easier but times change. I was thinking about running a ATI but decided not to (personal preference).

I guess I'm trying to figure out if I will get better performance running SLI or single card. I'm trying to keep this within the $300 range but it's hard figuring out what would be my best option.

My rig is as follows, i5 2K, MoBo MSI P67A-GD65, 8Gig 1600, 750W-PSU, Monitor will do 2048x1536. My Vid card is a BFG GTS250. System runs ok but I want to see games like BF3 run 1920x1080 with decent frame rates, I'm not looking for a bleeding edge Vid card or one that will break the bank.

Please give me your opinions for dual or single card.
 
You will probably get better performance with SLI, but there is drawbacks as well such as extra heat generated, and power used.

Depending on rebates/sales you could probably get 2 GTX 560's for slightly over $300, or a single GTX 570.
 
Not worried about heat issues, I got a nice case with plenty of cooling so heat should not be an issues..

And 2 GTX 560 Ti's would outperform one GTX 570 by a fair amount. But then you couldn't really just add another card in the future as you could if you just bought a GTX 570 outright.
 
I was giving that some thought but I can put 3 PCIe cards with the MoBo I have now so I could always add a third?

Even if I only ran 2 cards I should still get some great performance and this should pretty much put my i5 to the limit.

what about 2 of GTX560's TI? how much of a performance lost over 2 GTX570 TI, be? Would it be 30% or more? If so then going with 2 570's would be better..
 
On newegg, a single GTX 570 starts at $300, a pair of GTX 560 start at $340 for both, and a pair of 560ti starts at $420 for both. 560 SLI will beat a single GTX 570, and 560ti SLI will do even better, but what is your budget, anyway? You started out saying $300 but you end up talking about 2 or even 3 GTX 570 cards.

I say just get a single GTX 570, and if for some reason that's not enough of an improvement from a GTS 250, get another GTX 570. A single GTX 570 easily beats GTS250 SLI, so just that step up will be huge.

Yes, but he could sell both 560 in the future and use that money towards another card that makes both (560/570) look like bad choices.

not with 560 you cant add a third. correct me if im wrong but only the 580 and i think 570 in the 500 series can do more then 2 cards in sli.

A pair of GTX560TIs outperforms a GTX580 by a great amount in benchmarks.

My budget for now is $300 but in a few months I will have another $200 or $300. I was out of work for a while and got a new job so I'm getting caught up on my bills other wise I would just drop $500 for one new card but that's not a option right now.

I like the SLI option cause I can get a good card now and a second one latter. I'm sure by the time I buy the second card the price will have dropped some?

The 560 TI look good and the price is not bad. I could easily get a 560 ti now and get the second latter. I should see a nice boost in performance over what I have with just the single card. Then drop the second card in and I should be running nicely.

Here is another question that needs to be addressed. When do I start hitting a bottle neck with my CPU with having 2 GPU's? I'm sure there is a point where my CPU will hinder the GPU's?????

One more thing.. What about a PSU? I have a 680w now, will I need a bigger one?
