Quick 64bit Q

What's the difference between the 754 and 939 architecture?

939 is the latest but what sort of gain would I expect from a 939 3400+ compared to a 754 3400+ with same peripherals and rammies?

I am also talking agp boards here, not pci-e

[Domo-Kun]

939 is much more efficient, one of my mates has a 754 and my 939 blows it out of the water

The 939 Platform has alot more key features, Faster hypertransport bus, Dual Channel DDR support, newer chips are 90nm as opposed to only 130nm avaliable on 754 and the 939 has a greater upgrade path amongst many other things, such as PCI -e support

OK, I was gunna do a cheap upgrade for my agp 6800u...

I am currently using 2800+ and nforce 2 mobo... As I don't want to go new tech till it sorts itself out, I was gunna go a $150 754 mobo and $250-300 cpu just for the interim...

Most the 939 mobos out atm are pci-e which I don't wanna go atm...

You can still get 939 agp mobos fairly easily like the K8N Neo2 Platinum, or Gigabytes K8NS series, both are still easy to find and buy.
It would be just silly if you were getting a new mobo and cpu to buy s754, as there is no easy upgrade when you do decide to go pci-e (when you next upgrade the videocard), or feel like beefing up the cpu to dual core or whatever
