My current desktop computer is old, and needs a new CPU (look at sig for specs... Motherboard is ASUS P4P800-E) It is socket 478 and is completable with the Prescott core for Pentium 4. I went to Pricewatch | Find lower prices on computer hardware, laptops, computer parts and electronics to find the cheapest Pentium 4 for clocked at least at 2.8GHz. I found one here STARMICRO INC. - Detail for $40, and I found another one clocked at 3.0GHz for $55... Now I don't have much money (as I am only in highschool) So I was wondering should I get the $40 one and overclock it to make it equal? or should I just get the $55 one? And what are oppinions on STARMICRO INC. - Home Page starmicro And last what kind of new heatsink should I get, or should I just keep the same one that I have for my Celeron 1.7GHz?
