Ok now for the plans. I will add SDD. I plan on SLI. I will do this when ever i have a good night at 2-5nl. I will try out OCing, and i know i will need an after market cooling system for this. I want to try to setup my own liquid cooling, and i will add those parts later, and buy locally so i can talking to someone when setting up the system.

Concers are that i didn't want to go for an x2 of the 560s because of the shuttering affect explained in this article:

Also i selected the Gen 3 for the future PCIe 3.0 for upgrading later. Am i kidding my self or is actually going to be usefull also if it is should i spend that much money on a gtx570 now or just buy a budget and then upgrade when the new cards come out. This is only good if they come out before Jan12.

Thanks for the help in advance.
