Firstly this is not a topic about OEM vs Retail but in the case of buying a AthlonXP CPU OEM for approx. £6 - £16 cheaper than the Retail boxed one which includes an AMD approved heatsink and fan. I'm not an overclocker, just want to buy the whole package with CPU with HS&FAN at a good price. So, in this case is it worth buying the Retail boxed version or the OEM version and buy a HS&FAN separately elsewhere? Just for arguments sake: (Dabs.com) Athlon XP 1800+ OEM ~£113 Athlon XP 1800+ Boxed inc Heatsink/Fan ~£130 Thermaltake Volcano 7+ ~£18 So, first of all, would the Volcano 7 hs&fan be a lot better than the boxed CPU? Therefore is it worth getting separately the OEM CPU and Volcano7 which is the same price as Boxed CPU?
