Computer upgrade question

[nosch]

I am looking to upgrade my computer and wanted your opinions. What I have currently is below:

P4 2.4c overclocked to 3ghz
1gig memory
BFG 6800GT OC AGP

I want to switch over to an AMD CPU, but would like to keep my AGP card since it was just given to me at Christmas. The main use for this machine will be gaming, so how do these specs look for an upgrade:

Athlon64 3500+ or 4200+
MSI K8N Neo2 motherboard
I will keep the memory and graphics card

Is a duel core CPU really worth it right now? I would like this machine to last at least 2 years, so my thinking is that duel core may be the way to go. What do you think?

Thanks.

As you may already know, a $345 AMD dual core is coming out next month. If you spend $146 US now to buy a socket 939 processor, yes, you will be able to upgrade later to dual core. But, I find some prices don't dip down that much, that fast. So, suppose in a year the X2 3800+ sells for $200 US. So, you upgrade and find you've spent a total of $346 US which is more than the street price will be for that X2 3800+ coming out next month. Remember, that chip is 2.0 GHz & 512 K cache TIMES TWO. You can game and do other stuff like file sharing at the same time.
