I currently have an ATI Radeon 3870X2 video card, and am looking to upgrade it. Right now, I can snag either a Radeon 4870 or an nVidia 9800GX2 for $300, and I'm debating on which one I want to use. Here's how I see it:
If I bought a single 4870 now, I could always add a second one later and this would beat the 9800GX2 easily. Of course, this means I'd also end up having twice the number of power cables in my system, and I'd need extra airflow to cool two separate graphics cards (not to mention the added noise from two cooling fans).
If I bought the 9800GX2, I'd gain more performance than a single Radeon 4870 (I think), but I couldn't upgrade the performance further should I need it down the road (without getting rid of the GX2 entirely).
Of course, there is always the option of paying a bit more and getting a GTX 280 as well, but I think the GX2 would be a better overall value in this case (considering it's $150 less).
