I have been using an N450. Not too dissapointed. Obviously not as fast as the quad q6600.
The atom 330 seems to run well (provided you are not doing intense multi tasking)
And the D510 offers more. Would be interested to see benchmarks against a Q6600 or Q8300
The cost is so different. I can put together a mini itx using a £50 mobo, old HDD, and spare 4-4-4-12 RAM i have sitting around.
Or...I could shell out £100 mobo, £150 processor...etc etc
Huge cost difference...
