Looking to upgrade my P3-450, and was a little bummed to find out that I can't take my memory with me (the new boards all use DDR ram instead of SDRAM). I'm looking at a P4 1.8 Ghz and probably 512 DDRAM, but my real question is about getting rid of what I've got. Just out of curiosity, what do you think a P3-450 CPU and Asus MB with 384 Mb of SDRAM would be worth? I was thinking about either trying to get rid of the parts alone, and if that didn't work put a system together (need to add a case + HD etc), but I don't think that it would really be worth my while. Any thoughts? Also, any recommendations for/against the P4 CPUs or any of the boards? Haven't bought one in almost 2.5 yrs, so a little out of date.
