Re: 8800GT Sli for 1900x1200 or 8800ultra?
This is actually the only time I'd advocate SLI and this is why.
Before the 8800GT, the only choice was to SLI a couple of 8800GTS's or buy a single GTX/Ultra. The trick there was buying two 8800GTS's were about the equivalent of a GTX/Ultra in price and performance, so it's obviously better to spend the same amount of money for one card and then if you still want to later, you have the ability to still go SLI later with another GTX/Ultra.
But now we have the 8800GT which is half the price of the 8800GTX but almost the same performance (like 10 less fps avg from what I saw). So buying two 8800GT's and putting them in SLI actually gives you better performance for the same price of the single GTX/Ultra. Beforehand you'd pay the same price for the same performance, but now you pay the same price for better performance.
I hope I made this concise. I did my best.
