i've never had an intel. i've always went amd. it's not to far back, but back as far as the 900mhz. guess i've had 4 pc's. 900mhz, to a 1.4ghz, to a 1.8ghz and finally to a 2.2ghz. surprisingly great performance hits even though only @ 400mhz upgrades at a time. anyway, these new Intel Core 2 Chips with Conroe cores are looking GREAT!!! hrm, maybe a switch in manufacturers are due? but then again... amd's supposed to supply us with an answer next week with their response to these sweet, sweet conroe's. lol, it better be good. especially with those prices intel's set for these new chips! unbeatable?
