I run 2x8800 GTX's on my main rig and an Intel quadcore running at 3.2GHz. EQ2 (eg) runs slower, stutters more, on that rig in SLI mode than it does using one card.
EQ2 is NOT optimized for SLI, and NOT optimized for multi-core use. So, a single decent video card is enough to switch the bottleneck to cpu-bound. When you enable SLI, an additional burden is placed on the cpu trying to decide which video card to use, and so the game slows down.
I'd expect the same results for AoC at moderate screen sizes/resolutions, so I'd say stick with one card at least for a couple of weeks until we can get a read on things.
I'll be using a single 8800GT and a single Radeon HD2900XT until around June 1 - then I'll be back on the 2x8800 GTXs and can give a comparison.
