Since I was advised to start off with Snow Leopard (with AMD) and not with Lion, I now try to get it done with SL.
I don't really know where to start but I'll figure that out, first I need to know IF it is possible to run it on my machine.
I now have W7 (64 bit) installed.
AMD Athlon II x4 640 3.00 GHz
8GB RAM DDR3
Radeon HD 6850
Thanks in advance
