good choice of cpu i love my q6600 quad
try an asus maximus 2 formula like me, im running my q6600 at 3.4ghz right now but i have pushed it to 3.8ghz without any problems although that will depend on your chip there all different, i have had other q6600 that would only get to 3.6ghz but that is still a huge overclockfor a 2.4ghz quad.
i would like to state that im running a corsair h50 and currently upgrading to a full loop.
the asus maximus is a great board for overclocking it has a easy to read bios with plenty of features for overclockers (including cpu lvl up), the entire board has been made trying to make overclocking easier (which is why i chose it) this is a very popular board so theres loads of support out there on sites and on here.
the entire board features passive cooling to all the main components on the motherboard like northbridge/southbridge and is linked with copper heatpipes which does a great job of keeping those components cool when increasing voltage. it can handle plenty of ram (16gb maz) in ddr2 so you can keep your current ram. i also like were the power cable is, its in a nice spot for keeping cable management tidy and has 6 main sata ports and 2 speeding hdd slots.
the one thing that might put you of this motherboard is i have been told it only supports crossfire and not sli which wasnt a problem for me as i only use ati radeon vga cards but if you wish to use sli you cannot with this board but i do believe it will work with single nvidea vga cards.
i would also like to point out the amount of stuff you get when buying this board new, the instruction book is huge and packed with easy to read info, it also comes with 4 sata cables 1 ide and floppy cable 2 extra usb and a firewire port, an optional cooling fan and the lcd poster which is really handy for finding faults and the supremeFX x-fi sound card is included to.
i might have put a little bit to much info there and gone a little overboard
i just found this board to be excellent when overclocking my q6600 and the other cpus i have tried it with.
it may be a little on the expensive side tho but you get what you pay for believe me, out of all the boards i have tried this wins hands down.
saying that i have heard evga have been making some really good boards lately personally im an asus fan so i cant comment on other boards, i hope i helped and gave you another option to think about.
