My stepfathers computer just took a crap (4 yr old hp) so I was looking at the B110 and it looks like an awesome deal. Are the D-Series celerons a step up from the previous gen celerys?
Depends on the generation of the Celeron. If the previous generation to you means the Northwood core, then yes there have been some slight changes. The first change is FSB, going from 400 MHz to 533 MHz. The second one was the L2 cache being raised from 128KB to 256KB. EM64T (64-bit) extensions were added later on in the 3x1 and 3x6 models.
