jus lookin at the skull trail board and its not ridiculously out of budget,
"It can be yours for the trivial sum of $650 - inflated by the use of FB-DIMM server memory - but you will have to spend another $1500 apiece for two quad-cores 3.2GHz Core 2 Extreme QX9775 processors and $400 each for two top-line graphic cards"
not thats roughlt £325 for the board, £320 for 2 Q6600's £200 for 8 Gb 800 Mhz RAM and myself im not a gamer so thats £900 or lets say £1200 for everything else included. now £1200 for an octo-core 8Gb RAM machine is not bad at all,
Edit: jus realised u need diff RAM will up the price quiet a bit
