A friend of mine has just scored a new HP pavillion pc with a Q6600 and vista ultimate

It has an Intel G33 motherboard, Is it capable of being overclocked? Like say running the Q6600 @ 3Ghz (333x9 as opposed to 266x9)?
To bad it only has 1gb of ram and an 8400Gs it doesnt perform so well

I'm trying to convince my friend to get rid of the 8400gs and get an 8800gts 320mb or an overclocked 8600gt oh and another gig of ram to then it might be worth Overclocking the CPU

bottom line is Can the Q6600 be Overclocked on this motherboard (Intel G33) ?
