There are alot of reasons, but I for one have had both and greatly prefer amd over intel.
i wouldnt say Low Range at all.... not sounding like im just trying to defend my old p4 here, BUT every1 dogs on p4 and says they SUCK at gaming and there horrible at this and that.... this is CRAP... i get tired of hearing this... ive owned both AMD and P4 and i prefer intel... not a fanboy just like them for some reason... but anyway my p4 3ghz plays ALL games out now including FEAR and BF2 on MAX... with all setts and everything at 40+ fps... so they do their job they dont suck.... AMD does have a better cpu... BUT P4s do not suck... games rely on ur RAM and Video card the most... cpu does play a role but ur vga is most importan...
