ECS PT890T-A vs 671T-M?

OK ... I was tired of sitting & staring at them in the store, so I brought them both home & now have to decide. (It was cheaper to upgrade my mobo than buy a NIC that works on Vista!!!)

PT890T-A: http://www.ecsusa.com/ECSWebSite/Pr...D=1&DetailName=Specification&MenuID=7&LanID=9

671T-M: http://www.ecsusa.com/ECSWebSite/Pr...D=1&DetailName=Specification&MenuID=7&LanID=9

Main differences (that I can see)

671T-M only has 2 expansion slots, but has onboard video (in addition to PCI-Ex16) & the DDR2 is 667Mhz

PT890T-A has 4 expansion slots & can take 2 more IDE drives, but has no onboard video & the memory is only at 533Mhz.

The other main difference (& the one where I could use your help) is in the chipset, audio driver, etc.

The 671T-M has SiS for all of that (audio is realtek & lan is broadcom) ... & the PT890T-M has VIA for everything. Any thoughts or preferences between the 2?

As of right now I'm leaning toward the 671T-M, simply for the faster memory ... I'll use up the IDE & SATA connetions right away, but if I really need them I can add a controller card ... even tho that uses up one of only 2 slots.

Thanks in advance!
