Thinking about overhauling my PC for Christmas

Hey im new here and want your opinions on the hardware I have chosen for the build I will be doing for Christmas

MB: Asus Sabertooth X58

CPU: Intel i7 930

Memory: Patriot Viper II 6GB 1600MHz CAS 8-8-8-24

Cooler: Noctua NH-D14

i already have a Antec 900 a 650w power supply and a GTX 260 i was hoping to either add a second 260 or wait for the GTX 570's and grab 2 of them

what do you guys think overall, any suggestions?

And thanks
