I was going to ask this as well....
Crossfire is better than SLi though but I think you're right that SLi'd GTX's would beat crossfired and oc'd 2900's. Especially with bog standard AA when gaming.
W3bbo if you are going to put the cards under watercooling then I'd go with the Crossfire solution in a heartbeat. Voltage scaling that surprisingly works!!!!. I just wish someone would go the whole hog with the volts to give me a range to work with. I've had a little success but I'm unsure about pushing too much on the new 80nm core as my last card was a x1900 and worlds apart on volts/overclocking.

In call of juraze the cross fire achualy did worse then a single card.
The GTX is a powerful card and if you are thinking of switching you might as well just get another gtx and a new mobo as if you have a P35 mobo you only get a 4x lane. Crossfire on a 4x lane with 2 overclocked 2900 pros i dont think will beat gtx. Specialy on games with not particulary good crossfire settings. Plus you dont get 1gb of memory if you have two 512mbs. You only get 512mb therefore the 756 on the gtx is more usefull.

Make sure you purchase some ear plugs aswell
Game performance you'd stand no chance
want to bet ?
Pointing out a a particular game that does worse in crossfire is irrelevant seeing as there are games on sli that also do worse or not work at all.

A CrossFire tandem made out of two ATI Radeon HD 2900 XT cards is quite a different thing. Costing about $800-1000, which is comparable to the price of a GeForce 8800 Ultra, this configuration outperforms the Nvidia solution across a number of applications. Our testing has shown that ATI CrossFire technology enjoys a solid support in Windows Vista, obviously due to the high-quality Catalyst driver for the new OS.
That paragraph is taken right out of the conclusion from the above review. So basically a crossfire solution is faster than 1 ultra and there for faster than 1 gtx.

Right just thought, if you buy into crossfire ain't you looking at like £400 when including the price of a motherboard and 2 of the 2900's?
Would get better performance by getting one of the sub £100 SLi boards and a GTX for £300, plus less power usage and heat.

Then add the fact you can get 2x 2900Pro's and overclock them past XT speeds for about $600.
