yes I agree with catch on his line of posts here in this thread...
go with amd if you want performance/price that is excellent/low...
also the numbering system is representative of the equivalent performance of an intel processor... of course going above the 2100+ series you are getting a little farther away from reality... the northwoods are performing better by this stage...
the 1900+ is a good processor...
considering the heatsink... anything that has an amd logo above around 600 mhz NEEDS a heatsink... you can aircool if you want...
the xp series of athlons need proper heatsinks and some of them are not that easy to plop on... however for the person who burnt out 3 processors... amd athlon xp's are very resilient to heat contrary to popular belief... they can take high temps... to burn them out whoever put them in did something wrong... you cna't burn out 3 straight without doing something wrong..
if you actually think about it... you would NOT mind paying another 20 dollars for a GOOD heatsink that will keep your cpu running at any cpu usage... and your temps at a manageable level... also USE thermal paste... it helps conduct heat better but read up on it.. I know of people plopping a pound of thermal grease onto their cpu coolers and then complaining about temps... um... heat can't conduct as well through a pound of sludge
final words? go with what catch is saying... save some money... buy an AMD processor and heatsink/thermal grease and you are set...
about the temps... a lot of motherboards are coming out with safety features.. I believe that Asus has an autodetect feature that shuts the system down when teh temp goes above the trigger level...
g.luck making a decision.. but 1800 is best price and 1900 is not a bad processor..
