Water cooling is the best way, most definitely. I would look into getting one. You might as well upgrade that RAM too to get the most out of your CPU OC. Get a Geil ONE series with the 1.5CAS or the OCZ high performance ones too. That will compliment well with 2.8GHz. Get a good power supply too and also a nice 7800GT or 7800GTX would do wonders for your system. Then, you'll need to upgrade that motherboard, lol.
