When you get down to it, the name on the chip has less to do with performance (nowadays) than the mainboard, the memory , etc. etc.

With Intel. AMD, you might want to look at the actual specs but what does that really tell you about the processor performance......nothing.

Just get the least expensive and fastest one you can get.

I would choose AMD XP processors for the fact they don't overheat (when heatsinked properly,etc.) and per clock cycle get more done than their counterpart over at Intel.
