Sapphire 4870 1gb or XFX GTX 260 Black
 

I want to upgrade my graphics card but I'm having a bit of trouble deciding between the Sapphire 4870 1gb and the XFX GTX 260 (216) Black Edition. I know that the new GTX 260s perform better than the 4870 1gb in the benchmarks, however I have a crossfire board and I'm considering getting a crossfire setup later on, hence the reason I'm debating between the two cards. Would it be more worth while for me to go ati and crossfire up later on, or should I just stick with the XFX GTX 260?

Think your answer depends first on ya motherboard chipset ( P34/45/X38 or X48 ) secondly the game resolution you play on... thirdly is your power supply up to it ? and last but not least your wallet ? as 2 of these card will suck a nice amount of power out of the wall...
