Hi guys Have you seen this BEAST of a motherboard: Intel D5400XS "Skulltrail" Intel 5400 eATX (Socket 771) Supports two 45nm Extreme processors in an LGA771 socket with a 1600 MHz system bus. The mobo it's self costs over £400, plus the two CPU chips you have to buy lets say the QX9650 which is a grand total of £1800 lol madness. You would need a pretty powerful power supply considering it also it supports both SLi and Crossfire (not at the same time lol), so you would need a monster of PSU for this rig.
