I need your help in getting one of these.  Which one would you buy, and why?
1. $119 for the 4800+ OEM (newegg)
2. $99 + shipping for the 4400+ (TD)
3. $119 for Opteron 170 from zzf
4. $63.50 for the 4200+ (newegg)
I am concerned by the heat output.  Opteron 170 supposedly gets hot when OCed; 4800+ doesn't OC as much as Opteron, but is cooler, and is OEM; 4400+ not sure much about it but it is cheaper with full retail warranty (TD charges shipping, but you get the copper pipe cooler and only 200mhz slower than the 4800+; and 4200+ is nice, but only 512k per core L2 cache.  I want 1M per core.  Not sure if it will truly be faster, but I feel it is better?!  Help!!! I want to buy one of these soon, before they run out.  Can someone give me a real life answer?  Please, no C2D talk.  Thank you.
