the new celerons are better than the p4s
that, and they are crazy easy to overclock
you can overclock a 1.8 ghz up to a high 2 ghz without any special cooling (read: stock fans)
as was said before
celerons USED to blow
intel has really made some progress in their last generation of chips
i bought a 1.8 ghz prescott (i think that's what it was) w/ ECS motherboard from fry's for 60 dollars
i added a gig of ram and a decent power supply
i am in the process of loading it up tonight, i'll post how it runs here to let you guys know
from what i've been reading, if i throw a decent video card in there, i should be able to run just about anything that i'd want on my arcade (we'll just see how the processor heavy mame handles it)
the only thing i'm worried about, is getting null dc to run on it
edit: everything i tossed at it (that mame can run well) ran perfect, mk3 included
it's late, i'll let everyone know more tomorrow if they are interrested
