Bridged PCI and bandwidth

Hello,
I want to buy a motherboard that supports the old PCI ports (to use for my soundcard). i read that the boards that support the Z87 chipset offer "bridged" PCI connections and not "native". How could this affect the performance of the card?

Moreover, I was suggested to get a motherboard with as less as possible PCI ports, because the bandwidth which will be shared to them will be larger (divided to less parts). Does this mean that regardless of how many PCI cards I'll use, the bandwidth will always be divided? And if so, could it cause a functionality problem?

What cards are you trying to run? Most PCI-based cards won't have any problem with bandwidth being divided between them, unless you have like 4 or 5 high performance cards all at full load at the same time lol

If you're simply adding a sound card, there is plenty of bandwidth available without any kind of performance loss. Even with adding a wifi card or something on top of that.

Checked some music production forums and ran into people with the same sound card. Some of them had problems with it, some didn't.
The answer I got was to go for a motherboard that comes with two PCIe controllers (to leave one of them *free*), so that the bridged PCI won't interfere with something else.

So, could you please tell me how do you figure out the number of PCIe controllers that a motherboard supports? I've read many boards' specs, but I couldn't get any info.
