celrons do not have HT either.
I have benn build gaming systems and celrons work great until you multitask the HT and cache makes a big difference. I have not built any p4 systems or celeron systems for almost 2 years.
For a low end system Get an 805 @75
Waiting for the low price quad core Get a E6300 @180
Want the best price peformance today Get a E6600 or amd fx-60 at $320--$350
Wish list: wait for the Q6600 at $500 next fall????
I am running an e6300 waiting for a cheap q-series with a p5d-dh crossfire x1950xtx, i also run x2 4200+ mini pc, am2, a x6800 wtih a striker and fx-60 939 and my 2003 3.0c @3.5ghz.
My kids on 560j running 4ghz he can im, game and play music all day on both monitors including no lag with oblivian. If you can find an older board cheap the 560-661 chips are great bargin at $90-$100 on ebay - i just sold one for $90
