Intel 1000MT desktop 8390 vs 8391

[trikster2]

Shopping for a NIC recently and I noticed for the intel 1000 MT there are two different part numbers floating around: PWLA8391MT and PWLA8390MT.

The 91 is the current model, are there any improvements over the 8390?

Thanks

Thanks cmetz

I really did search, but on 1000MT not "1000 MT"

I just looked at the specs for both chips, everthing looks about the same but the newer chip supports PCI 2.3 (vs 2.2) and ASF 2.0. No big difference, on newegg there is only a $3 difference betweent he two parts.
