Whats a good motherboard for overclocking a E8400
i was looking at asus Asus P5Q-E x38 http://canadacomputers.com/index.php?do=ShowProduct&cmd=pd&pid=018815&cid=MB.157

but it does not allow crossfire set up. i dont understand how it can do crossfire x8 but not x16 when it has two x16 PCI-E 2.0.

im looking to spend 200$ max on the mobo. so any suggestion?

on the side note anyone knows untill when PCI-E 2.0 is gonna be around?

For overclocking in General, anything w/ an Intel P35 or X48 chipset would be ideal. You would be able to Crossfire and overclock the P5Q-E, it has two PCI-E slots... not sure what speeds they run at when linked; has the P45 chipset. On a side note, nVidia's 680/780i platform is also pretty good for overclocking if you wanted to go that route. EVGA makes some pretty decent boards in that category. For Intel P35 chipsets, Gigabyte makes some really good boards which have a lot of overclocking potential.

Like my board...
EXCellR8, has about hit the nail on the head, Gigabyte does make some really good potential boards, if you know what your doing.
Just be careful, and make sure you have sufficient cooling.

that Asus P5Q-E x38 is a great overclocking board. u would be proud of it.

The P45 boards are excellent overclockers and the northbridge runs cooler than that on P35 boards. The P5Q Pro and GA-EP45T-Extreme are excellent choices.
