Yes, for power to price ratio its undoubtedly in favour of the 3000+.
If your holding out, I'd wait for the 64 + PCI-E evolution, it really just is on the horizon. PCI-E is really, really fast... I mean this thing has made GFX cards look like a huge bottleneck. And 64 bit processors are coming down in price.
I guess this is just a budget machine though? In that case I'd go for the XP 3000+ if it was my choice...
