which country do u live in? if u live in australia i hav some info about it. AMD Athlon 64 3500+ is a really good board at around $400 (this was a couple of months ago, like all prices listed) or a AMD Athlon 64 3000+ which is about $240. Sempron isnt that good if u want performance but itll do the job if u just want to use the pc for basic home use (like surfing the net, checking emails, occasionally playing games, etc). If ur getting a new mother board get the Gigabyte GA-K8NF-9 at around $190 and if ur getting a new graphics card get the Xpertvision GeForce 6600GT at around $270. This information came out of a magazine which i buy and these are really good components if u want a value system. Also with the processors if u want a good upgrade path for the future, whatever AMD processor u get make surre it is Socket 939.
Hope this helps
