Upgrading 7900 GTX in SLI to...

Looking to upgrade a pair of 7900 GTX cards (512Mb each, in SLI) to either a GTS 250 or a GTX 260-216.
I get that the performance on the 260 is significantly better than the 250, but I can get a 250 for about $100 and the cheapest I've seen the 260-216 is 225. Is the difference really worth the $125, given that I'm starting with the 7900 GTX?

A 250 GTS will at least double your FPS over your 7900GTX SLI. Edit: was looking at the GT not GTX. For $100 the 250GTS is a slightly better buy over the 4850.

The 260 GTX for $200+ is a bad buy; the 4870 and 5770 perform on par and are $40 cheaper.

right on - thanks for the thoughts. Am probably going to stick with Nvidia regardless of the better performance/$ from the ATIs only because I'm running a 680i chipset and it makes things like SLI that much easier.
Will probably just spring for the 250. - I'm running a 750W PSU...any chance I could get away with running two of them in SLI?

Easily.

The power consumption of the two cards is the same plus or minus 10-20w at load with some overclocking. The board spec for a typical GTS250 is around 105-125w under max with actual power consumption being less. A typical 65nm 9800gt uses about 80-85w under load at defaults which is the same as a 90nm 7900gts.

By the way in my other rig I use a x1900xt and didn't think that it used that much power. :o

2 7900GTX's in SLI is about a 8800GTX, I don't think a GTS 250 would double the FPS.

Your right, I was looking at the 7900 GT SLI not the GTX.

^Was about to say that.
The 250 is about equivalent to a 8800GT/GTX or 2 7900GTX's. I'd for a 260, 275 or a 5850 to get a yield (+dx10 or 11).

Ended up getting the 250 - FPS is considerably better: L4D2 is giving me just about 2x the frame-rate.
Next step will be to pick up another card and run them in SLI.
Power consumption is fine. Under normal load I'm showing ~150W, and while gaming it gets up in to 200-250W. With 750PSU, I think I've got plenty of headroom.
