Just a quick question, what would be faster one 9800gtx (512MB) or two 8800gts (320MB) in SLI?
Also im running Intel E2180 (Overclocked to 2.6-2.8Ghz), would my cpu bottle necking any of the GPUs?

Thanks,
 
If the OP plays at resolutions higher like 1080p,he'll be fine because higher resolutions are more dependent on GPU not CPU;whereas, lower resolutions benefit from a faster CPU.
But overall,upgrading to a faster quad core CPU will give the OP a great boost in performance.
 
I say go with the two 8800GTS 320 cards.

Of course as Mazair points out the 320MB would be a problem in some more modern games especially at higher resolutions, but not all games will suffer from that. Games that are straight console ports, for example, tend not to use as much vRam since they were designed to accommodate the limited memory on the 360 and PS3. Not all games need so much vRam that two 320 cards would run slower than one 512MB card. Just depends on what you play.
 
Those 320Mb cards use the old G80 core, not the G92, as does the 9800, so they handle AA terribly, tend to run hot and burn quite a lot of power for their performance and you'll have to deal with the problems inherent with SLI as well. For those reasons I'd opt for the slightly slower 9800GTX.

As a side point, why such old hardware? Current cards are far more efficient.
 

True but on resolutions like 1080p,320MB RAM isn't enough
