Im thinking about buying a new processor for the rig in my sig. I really dont feel like buying a new mobo, so im trying to get the most bang for my buck. I figure id go for a athlon xp 3000 barton. I didnt want to spend much more then $150. But anyways, im wondering if i will need to buy a heatsink, ive already got a SLK-800 on my 1800 but i dont know if it will keep the 3000 cool. Thanks.
