i was looking to get a linksys pci with speed booster to match my current router which is also a linksys speedbooster....(is there really that much of a difference with speedbooster anyway from the original)
You are limited by the speed of your Internet connection. If you're using cable for Internet, there will be no increase in speed beyond 10 mbps. Save your cash, unless you're using a LAN and are sharing files. In that case, I would match the card to the router, not because of speed necessarily, but because of the ease of getting support when something goes wrong.
You'll find that with a Linksys router and a Netgear ethernet card that when something goes wrong, Linksys is likely to say the problem is with Netgear, and vice versa.
In any case, you'd get better LAN performance by upgrading both the router and the PCI card to wireless-N. Your Internet connection will not improve, since the pipeline from your LAN to the Net is a constant.
