i played around (did read a lot @ ocforums.com) with fsb cause the cpu is not unlocked..
well i managed to get it up to 2255 ghz, with no heat problems,
but some of the linux games (open arena, true combat elite) i play just crashed (the system didnt freeze but the games).

maybe i can get my hands on 2x nvidia 6600 gt (pci-e) from a friend who still wants better gfx card(s)
but i doubt i can use them properly with my moboard.. (msi 6712)
