Upgrade processor or motherboard?

I am trying to find out what means of upgrade is going to give me the most bang for the buck.

I have a MSI K8N Neo Platinum (754) with an Athlon64 2800+ procecssor with 1gb (2x512) 400mhz Kingston Value Ram

Does it make more sense for me to just replace my processor and maybe get some new memory, or should I get a 939 motherboard and new processor.

Thanks

If that's an nforce3 board, I would bump up the cpu voltage by .05 for some overclocking, and skip the memory upgrade. 1 gig is plenty.

Also I have tried to do some overclocking, with the automatic oveclock options that the board has, but they don't seem to work, which is why I wonder if the motherboard is bad or maybe the OC doesn't work well because of cheap memory or because the Processor is a lower end Athlon64.

HAVNT had much testing in that area, but going from say a 2800+ to a 3400+ would defaintely give performance, but i wouldnt imagine that giant a boost. the memory is NOT an issue because unless you're maxing out that 1 gig, wont change anything. I say hold off till the Dual Cores are readily available. those SHOULD give you the maximum performance boost (if you can afford it) because the multiple threading will greatly improve encoding time considering there are a lot of applications in this market already designed with multiple threading technologies. again with this type of application, you want to do what you can to enable the maximum amount of data flow through your system. perhap if you're using giant files that are being read or written to your drives, the better option would be a better hard drive solution, like a raid 5 array (SATA or SCSI if available) to increase those write times
