Seems like a decent machine indeed, Ive also got the Intel E4500 2.2Ghz Core2 Duo, Ironically I'm also using the MSI P35 Neo Series.
I chose that board purely because it's fairly upgradeable, such as the possible idea of quad cores, but i ain't gonna bother with those not for a long time yet.
But you never mentioned the type of RAM your using? I was considering 800Mhz 2 Gigs worth, but I couldn't fork out enough for it, so I improvised and got 2 Gigs of 677Mhz.
Does me fine since me old computer was a Intel Celeron 2.6 Gigs on a Super All powerful! 400Mhz capable front side bus.
Hmmm the little blighter served me well, until my father got a hold of it and fried the board!!! .... Haiz, Parents....
