Depends on the card data rate
PCI Bandwidth 133 MB/s
PCI-E x 1 Bandwidth is 250 MB/s

you will be fine on PCI up to 108mb wireless. anything over and you will need PCI-E

then why does it say it supports 300mbps on the box?

133MB is ~1Gb/s. That's plenty for a single PCI card to have three 802.11n 300Mb/s radios running full speed simultaneously.
PCIE 2.0 x1 is 500MB/s. If he's talking about the board in his sig, he's got PCIE 2.0.
Regardless, neither bus will limit any current wifi card's throughput.

Huh? 300Mb/s / 8 = 37.5MB/s. That's just the maximum link speed. Wireless protocol stuff cuts that down some, then whatever protocol you're using to transfer data cuts some more. With a favorable environment, 30MB/s from a 300Mb/s card might be close.

...also don't forget that whenever throughput is rated (bits per second) it is always rated at half of it's full capability. This is the case because throughput is rated in half-duplex. If your connection is full-duplex (which it will be unless you are using hubs and legacy NIC's) then you will achieve double what it is rated under ideal conditions.
