I entered the competition in the VIA Arena Gamers Website, just for fun.
Guess what?
I won! A copy of Call of Duty: United Offensive and best of all:
a brand new ABIT AV8 3rd Eye motherboard!
No processor or memory, though.

Question, which AMD/64 Socket-939 has the best bang for the buck?

Best bang for the buck would certainly be the new 3200+ (2GHz) or 3000+ (1.8GHz) chips. The 3500+ is still quite expensive. Be carefull though, the 3200+ & 3000+ are 0.09 parts & most of the time the motherboard needs a BIOS update prior to installing those CPUs or you get not POST at all.

These prices (from xxx.xx) are in Euro, incl. VAT:

What should I go for, 130nm or the newer 90nm?
The latest BIOS for my mobo is from 12 Nov, 2004

AMD Athlon 64 3000+ "Newcastle" (130nm), 1800MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 139.30
AMD Athlon 64 3000+ "Winchester" (90nm), 1800MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 134.74
AMD Athlon 64 3200+ "Newcastle" (130nm), 2000MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 178.35
AMD Athlon 64 3200+ "Winchester" (90nm), 2000MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 174.38
AMD Athlon 64 3500+ "Newcastle" (130nm), 2200MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 231.01
AMD Athlon 64 3500+ "Winchester" (90nm), 2200MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 244.03
AMD Athlon 64 3800+ "Newcastle" (130nm), 2400MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 540.19
AMD Athlon 64 4000+, 2400MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 1MB L2 Cache from 622.93
AMD Athlon 64 4000+, 2600MHz, 200MHz FSB, Socket 939, Boxed 64 Bit, 512kB L2 Cache from 652.34
AMD Athlon 64 FX-53, 2400MHz, Socket 939, Boxed 64-Bit, 1MB Cache from 774.72
AMD Athlon 64 FX-55, 2600MHz, Socket 939, Boxed 64-Bit, 1MB Cache from 715.36

The 3200+ (either Winchester or Newcastle) should do nicely. The Winchester based one is less power hungry then the Newcastle but aside from that they both will perform exactly the same.

Hi Didou, you had told me a few days back that the AthlonXPs were not optimized for DUAL CHannel, so I looked into getting an Athlon64, for a socket 939 MoBoard so that I could have DUAL Channel, plus room to upgrade the CPU in a year or so.

Would you mind taking a look at these 2 and telling me if Im wasting my time ?

Also, you mentioned to 'RealBlack' about the chips not POSTing on some MoBoards, and might need a BIOS update first....would it be too much to ask how that is done?
This is my first build, and I don't wanna screw anything up..
Thanks, peace.
