Quite honestly, no. If you can get one powerful card, that'll be sufficient. Like the 280 would be your best bet. Even then you'll need a pretty hefty OC on the CPU to not bottleneck the card.

The only cards you'd probably notice a significant difference from 1 to two cards would be 8800's (or older 7xxx and 6xxx series).

What CPU you want to use?

Odds are, if it is a dual core, it will bottleneck the 280's. You could SLI 260's with less bottlenecking or even none at all if you OC high enough, but i doubt it. You'd be ebetter off with a single GTX 280.

Hmm the 4000+ dual core series are really pricy but would an Athlon 64 X2 4800+ be alright for these cards?

I ran a 3.5ghz Athlon II with a single gtx260 for a long time and in some games I would use 100% gpu (even WoW-Cata hit 80-100% on max). For 60$ in the used section of the forums I upgraded to SLI and would get 50-70% usage max in demanding games like Metro.
AMD, I give up.

A 4800x2 would do fine, provided you overclock it. You'll need to run it @ 3.0GHz or better to take full advantage of the video cards. So good cooling is a must. FWIW, on my 939 rig @ 3.0 GHz with one of my Evga 9600 GSO's (OC'd hardcore) I managed 25.41 FPS average on the Crysis 1 benchmark with evrything maxed and full AA and AF.

I was thinking of buying that zalman cpu cooler thingy looks fancy,
can you watercool these cards by chance?

You can watercool anything if you have enough money. No point in watercooling the GPUs'. If you want, water cool the CPU, that would definitely help you get a higher overclock. That and you could even use it on your AM3 rig if you so choose.
