So at this point in time, my plan was and still is to build a new computer based on AMD64. I currently run these four machines.

Intel Pentium 4 2.6C (Northwood)
Gigabyte 8IPE1000 Pro Motherboard i865PE/ICH5 chipset(the expensive one )
512 MB RAM
80 GB HDD
80 GB HDD
DVD Burner
CD-RW/DVD Combo
Floppy
Radeon 9200SE 128MB
Agere Modem
Netgear WG311 Wifi using Netgear Drivers
Netgear WG311 Wifi using Atheros Drivers
Windows XP Pro SP2
-----------------------------------------------------------------------------------------------------

AMD Athlon XP 2500+ Barton 1.83GHz(Unlocked)
MSI Motherboard VIA KT600 Chipset(can't remember which one)
512 MB RAM
80GB HDD
Floppy
Radeon 7000 64 MB
Netgear WG311 Wifi using Netgear Drivers
Linksys 54G Wifi using Linksys Drivers
Fusion BT878A TV Tuner
Windows XP Pro SP2
-----------------------------------------------------------------------------------------------------

Toshiba 5105-S701 Laptop
Pentium 4 Mobile 1.8 GHz
512 MB RAM
60 GB HDD
DVD/CD-RW Combo Drive
Toshiba WiFi B/G using Toshiba Drivers
15.4 Inch Screen
Toshiba AMR Modem
Harmon/Kardon Speakers with Sub-woofer (built into laptop)
-----------------------------------------------------------------------------------------------------

Last but not least

AMD Athlon XP 2000+ (Unsure of core but it has a square die)
40GB HDD
Adaptec SCSI card
Biostar M7VIG Motherboard VIA chipset
------------------------------------------------------------------------------------------------------

I would like to build a new machine with an AMD Athlon 64 Socket 939 CPU.

I do not care much for Dual Core as I do not see an immediate need for it in my own life especially with its current pricing.

But my problem remains as such.

Which of the four machines should I get rid of. Unlike some of our financially spoiled members here I need to sell at least one of these machines in order to make room for thisnew computer. The LAPTOP must stay however. I hang onto the Athlon XP 2500 becuase of it overclockability and because it represents waht AMD is all about.

So what CPU do you think would suit me in the form of a new computer?

Also, when will DDR2 be out for AMD and what else is coming down the pipeline within the next year?

I hope that all made sense. I've been out of the loop for some time now and would like to know what is up and coming and what is going on right now.
