I'm impressed by the IGP, even more if this is not the fastest version they will have,

but the overclock limitations
if you have the cheapest version without the unlocked multi and without turbo you are left without options? while you can run a clarkdale g6950 at 4.5ghz...
this "100mhz" reference clock, limited OC comment doesn't help, I'm at this moment using a cheap overclocked e5200, it seems this kind of CPU (really cheap with lots of OC potential) is dead.
