Motherboard and Overclocking help

[KaneStatton]

Hi all,
I'm relatively new to re-arranging and replacing things in my PC but currently I have and am able to change PSU's, Harddives and GFX cards fairly easily and confidently.

Its come to the time that I have to change my motherboard as it is some crappy one that came with the PC and does't allow/enable me to overclock the Q6600 and I need to really with the coming of ArmA 2 and future games.

Are there any good quides on replacing motherboards (what motherboard to go for?), what is what and how to overclock the Cpu ? I only want a mild overclock to say 2.8ghz or there abouts is this possible without going under water or voltage mods ?

Thanks for any help
Kane

No specific budget it just needs to overclock fairly well (3.2 would be excellent)
for as cheap as possible really, under £100 is a must though.

With the q6600 is 3mb of ram good enough ? or should I go up to 4 ?

Is a Abit IX38 QuadGT Intel X38 any good?
It has crossfire support so I could get another 4850 for cheap from B grade.
