8800GTS SLi or GTX 260 core 216 (don't have pcie 2.0)

Okay, here's the problem.

I have:
mobo - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
cpu - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I had:
GPU (but it died) - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I run a 22" wide monitor at 1680x1050

I can spend $220, so this is what I'm looking at:
2x 8800GTS (total $220) http://www.newegg.com/Product/Product.aspx?Item=N82E168...
1x GTX275 (total $220) http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I had a 8800 gts before, and it ate almost everything I ever threw at it. I play wow, cod4/5, tf2, l4d, etc. I don't own crysis.
wow, cod4/5, tf2, l4d... all those games i've been able to play with all the settings on max (except wow because it's gotten more graphically intensive lately, so i had to turn it down just a LITTLE but they were on max). I wish I could tell you what the fps's were, but now that the card is dead, i can't really test that out for anyone  , but i can say that they were all suitable enough for me, and they always looked fantastic.
also, not always, but sometimes i turn vsync on because it helped reduce screen tearing. My monitor is 60hz, if that matters at all to any of the info. But I don't always have it on, just sometimes, it's weird that I like to switch back and forth.

I like the idea of running two cards in sli for the performance, and for the physx card idea, but is it worth it to get these two old cards? And will they perform better (for what I mentioned I want) than 1 gtx?

I have a 700wt psu with the right power connectors, so that's not a problem, and I have 8gigs of 5-5-5-15 ddr2 800 ram.

Just don't know what to do! What does everyone else think?

Thanks in advance for any help and info

EDIT: Sorry if this post is crap, I just had it typed up nice, and went in to edit in some pertinent information, and accidentally clicked "Delete Thread"... needless to say it's late and I was in a hurry to re up the post. Sorry if it's sloppy, all further posts will be more grammatically better and more intelligible!
