Hi all, I'm using the amd athalon64...i am about to purchase my OS, however, I was wondering which would be more beneficial. Windows XP PRO 32bit or 64? I was thinking that with the compatibility of the cpu, it would be beneficial wo buy the 64bit verison....would this be better? is there anything noticeable? im thinking that all of the hardware i have will have compatible drivers, so i would avoid that mess...although im not 100% sure about that....but, what do u guys think? Also, im browsing the net for the cheapest Operating Systems. Ive found some for like 80 bucks. How reliable are these OEMS? i mean, i know that microsoft will give you a new one if someone sells you a bonk product, but, what if they are selling me an OS for a DELL? is that covered in the license agreement if i dont own a DELL? Anyone know anything about this? Finally, does anyone know where I can buy the CHEAPEST version of win xp pro, that is going to be safe, with cd key and registrable code? Thanks GUYS!! Chaz D.
