Ok, little change of plans Now I have ordered these parts:

Pentium E2160
DFI Infinity Dark P965-S
G-Skill F2-6400PHU2-GBHZ
Optiarc AD-7170S-01 sata

Now I have a larger budget for the videocard. I'm thinking about buying a used 7900GTX/7900GT 512MB or a new X1950XT 256MB.

edit. I will post pics when I get the parts.
