Where and how would one go abot building a cheap but good dual processor system?

I'm interested in learning. I wouldnt need to buy windows pro because i'd use somthing like freebsd or linux on it instead.

Anyone else every tried somthing like this?

Cheapest Dual would be an older PIII board with dual PIII CPUs... of course dual PIIIs would not be as fast as a single modern CPU.

You get DUAL because you need horse power more than money savings, hence they aren't "really" cheap... why do you think AMD and Intel sells server class CPUs for $1000~3000 to allow 4~8 way CPU processing.

The best value dual CPU would be AMD MP CPUs... About $180 for an AMD MP 2600, each.

i recently got a dual p3 board good up to 1ghz per cpu for like 55 bucks in the retail box.

Not trying to discourage the use of TSG website but this website is/has been great for ALL dual cpu associated subjects(that's what the site is dedicated to). Link:

Dual cpus are used mostly in Servers and Macintosh systems. If you want to build a screamer, use dual cpus and setup your hard drives in RAID, use Server memory and turn on the air conditioning!

Yeah, just was curious. IT seems to me for what i do it could make some sense to just invest in an older dual cpu computer, rather than go out and buy a brand new one.

Well... that depends... Its easier to do so if you already have some PIIIs laying around. $55 is a good price for a dual board.

The fastest P3 (1.4Ghz) is about $220 (each). The 1Ghz P3s are about $75

$150 x2 PIII 1ghz
$ 20 x2 cool HSFs
$ 55 - Motherboard
---------------------
$225

vs.

$ 85 - AMD XP2500 CPU with HSF
$ 85 - Nforce2 mobo (Add $40, get firewire, dual LAN & RAID)
---------------------------------
$170


Even x2 PIII 1.4Ghz CPUs would not keep up with todays. P4 2.4 or AMD 2400 single CPU systems. Dual CPUs don't mean double the computing performance... Usually a 25~50% increase, due to the overhead. Also, unless the software supports it, they would only talk to the first CPU. (unless you assign it specifically with a tool or OS - which could be handy... tell [email protected] to run on #2 CPU) :)

Again, i was planning on running on one of the great os's. those that support smp right out of the box.

I think i'll wait, perhaps until i have enough processors.
