Hi all, and thank you for taking the time to have a look at my thread. I have 2 Pack-Bell Ixtreme desktop pc's, one is a x6618 and the other an x2613 I would like to max out my systems with the best availible CPU's these pc's can handle. I dont want to get into buying a load of bits to upgrade, maybe a better heat sync or fan but just the option to put a better chip in with what i got so to speak. I will endevour to give anyone who can help any extra info that is required, i cant seem to find the stats on the net to supply here. Thanks again for any input. Regards, Vale.
