I'm tempted to buy an Athlon 64 processor as well....but I only have a budget of $620...
right now is the absolute worst time to buy any kind of hardware.
well i guess serial ata drives are okay, but even then the sata300s are coming soon.
as far as athlon 64, you DEFINITELY want to wait for socket 939. the current sockets will only be supported to the end of this year. where's the upgrade path then?
if i were you, i'd get one of the older boards for really cheap. that crazy intel sl6z3 chip or a barton 2500. either will OC like mad.
the reason you want to wait for socket 939 is because it's unclear which chipset will work the best. for instance, the nforce2 vs. VIA. i don't know anyone that likes the VIA over nforce2, except for that one crazy poster who probably got banned. socket 939 is due out in march or so, but i'm going to wait until the dust settles.
i see that you've got an athlon 2000 and ti4600. that should be a decent performer in most situations.
i don't think you're absolutely intent on burning your money, so try to hold out for just a couple of months.
