if you look at the specs the 260 is pretty much on the same level as the 4870 and spanks the 4850 by 15-20%.
Tho, I guess if you not a Cutting Edge gamer then maybe the saving 100 bucks on a 4850 is for you. On the other hand, if your planning on playing crysis on you 24" panel and want the settings looking good your definitely better off splurging for a 260 card.
That is my take.
On the other hand if you can get a 4870 this cheap I'd opt for that since I think the card has not been fully optimized yet and the specs just look better tho, it's a bit worry-some when the GPU hits 90C - 100C. When we test with FurMark, GPU temp climbs up fast, almost reach 100C, quite terrible. Also the fan speed begin to raise up, when it going to 50% the noise level is already very high.
Stock cooler is more like a stock cooker. Can anyone say aftermarket cooler. I'm not liking the cooler (cooker) fan setup on these next gen cards at all.

You could get this for 5 bucks more I guess... It's really a toss up...
