I got the same CPU...I also have DDR2-800 RAM...at stock frequencies, my 2.333GHz CPU runs on a 333(DDR2-667) FSB clock. Putting the CPU up to 2.8ish only takes my FSB to 400(DDR2-800). How much farther you get your system to go from there depends on the quality of your RAM...2.8 will be easy, 3.2 might not...And get DDR2-1066 if you want to get your chip past 3.2, because thats already DDR2-916ish...
