I have a K8N Neo2 Platinum with Athlon 3500+ and 1gb OZC Gold memory. I want to know (relatively speaking) if the following upgrades make sense: Keep the mobo and change the cpu to an FX-55 and change the ram to 2gb fast memory. Would you do this? Leave it alone? or sell the components and build a more modern system (quad core ddr2 - etc).
