The K8T800 Pro also has a faster HT speed than the K8T800, but it also has a working AGP/PCI bus lock. You don't plan to overclock, but if you ever do the locked buses will help with that a lot.
Happy hunting.
I didn't know they dropped. I have not been keeping tabs on prices over the past month. I'm standing pat on my current mobo/CPU setup until S939 NF3-250 Gb/A64 combos are more affordable to me. To my knowledge no one is selling S939 NF3-250 Gb boards yet anyway.Originally posted by: Shimmishim

prices dropped recently... how soon you think they'll drop again?

There was a time when I was firmly in the S939 camp. I had bought into the hype that the single memory channel for S754 was going to send performance down the toilet compared to S939/940.
But look at Anand's own S939 vs S940 vs S754 benchmarks. Given the same CPU speed, S939/940 chips were indeed faster. Up to 11.4% faster in some of the SPECperf benchmarks and generally 2-6% faster in other benchmarks including gaming. These benchmarks make it clear that the A64 architecture is generally not starved for memory-bandwidth.
Given these results, I personally see no reason to eschew current S754 offerings in favor of S939 unless (a) the price difference is less than 6% or (b) you know the application you have in mind will benefit from the additional available bandwidth. In the future, when S754 has been relegated to the domain of 32-bit 256KB Semperons, sure S939 will be more compelling but not today.
