Good to know about HPA with the gigabyte boards. Seems easy enough to handle...if you know about it.
Since the motherboard has a built-in video card, and that the 2nd PCI-e 4x pipe shares the same bus as 2 of the PCI-e x1, am I right in assuming that I could:
Put an Adaptec 2240900-R into my x16 (i can use this for non-video card stuff and it won't break my onboard video, right?)
Put another Adaptec 2240900-R into my x4
Put an Adaptec 2232100-R into the 1 still-active x1
and then have 2 plain PCI slots for something like Adaptec 1205SA.
(I'm not looking to start off with all of these, I'm just making sure I understand the expandability I will have).
