The folks in the XtremeSystems forum have posted some images of the new ASUS P5W64 WS Pro workstation motherboard. The most unique aspect of this new board is the presence of four PCI-E x16 slots. Obviously, the first thing our readers will think of is coming up with a way to get two ATI "Master" cards and two standard cards and try for a Quad-Crossfire setup. Time will tell if drivers will allow this to function properly. However, in the meantime the gang is having a great time pushing the limits of the board and have managed to hit an impressive 472MHz FSB in their overclocking adventures. Although it might not be the ideal board for most, this unique motherboard will certainly be an interesting board to watch given the ample amount of PCI-E slots.
