I just reviewed a GTX260 216 (black edition) To say I was blown away is an understatement. Hopefully we will get a 4870 1GB soon to throw into the mix.

GTX 260, a much more professional product. There's a reason the ATI cards appear cheaper.
Please go away and come back when you have the slightest iota of what it is you're talking about. Thanks.
I'm actually swaying towards the GTX 260 (216) now that the 1GB 4870 has shot up in price. It looks like it runs cooler, uses less energy, has more stable drivers and is a similar price to the 4870.
Also, most of the 260 cards come with much longer warranties.
