Hi, im getting crazy to decide what will do with my current system.. my mobo died and thats all i have:

Quad core q9400
Quad core Q6600
Ram kingstom hyperX ddr2 800mhz 2x1gb
Ram G.Skill 1333mhz ddr3 2x4gb cl7
Noctua nh-u12p
Crucial SSD 64gb c300
2x samsung 500gb HDD 7,2k rpm
LC-Power LC6550 rev 2.0 550W
Asrock p43twins 1600
Graphic Card nvidia 8800gt 512mb gddr3
Graphic Card gigabyte RV5850 OC

I was thinking about 2 options:

1)Costs 45€
buy a 775 mobo (Asus P5G41T-M LX or Asrock G41M-VS3 R2.0) and use this 2 computers:
