9800gx2 vs gtx260 Poll. Pick for me!

Guys, I can't decide what card to get.

I am torn between the gtx260 and the 9800gx2. Both are similarly priced. On the egg, the 9800gx2 is about $300 and the gtx is $270 ($25 MIR = $245).

I want an nvidia to fold on as well, not just game, although I do game a lot. I mostly play FPSs and RTS. I'm concerned about micro-stutter and if I can't use SLI, the card is about as good as my current 8800gts g92.

Which card is better for the long haul?

If there is a better nvidia card that'll do the job, let me know. I don't want any ati cards b/c they can't fold worth a damn. So please, don't bring up the 4850 or 4870. Those would be my choice if I didn't fold.

Edit: I have a 650 watt psu running a q6600 @ 1.5v, and a mcp655 pump. If the 9800gx2 takes too much power, I'll end up having to go w/ the gtx260.
