How well does a Intel C2D E6600 overclock?

Hi guys, I have a intel c2d E6600 and planing on overclocking it my board is a Abit ib9 775 and my case is very well ventilated (Lian-Li Case) but I have a stock heat sink.

Nothing overclocks very well with the stock heatsink, period.

With that said, why does this machine need to be overclocked?

Your 8400GS video card is a huge bottleneck, at least if your end is to game with the machine.

I want it to perform better than my laptop, its kinda embarrassing that it can't encode a video or run faster than my macbook which was weird. Then again i only spent $300 on this system. Video card is the only one in my price range that would be able to run on macs so thats why i got a crappy one lol only $5 after mir

how much did you spend on the macbook?

that was $2100 dollars, but I its not like a top class performer you get get for half the price like asus g73 series

you will need adequate cooling for the CPU or heat will become a major issue.
i had a E6600 at up to 3.6GHz but had it most of the time at 3.0GHz - 3.2GHz.

3.0GHz - 3.2GHz should be fairly easy to achieve by simple raising the FSB. for a 3.6GHz you might need a little bump in vCore

Thats not bad, What kind of heatsink did you have on it?

i used a ThermalRight 120 Ultra
