Just buy a pci wireless network card and install it on your current motherboard. You don't have to change your motherboard for wifi.
Does you motherboard have a 16xpcie slot? If yes you can go for a PCIe video card from nvidia or ATi. If your mb have only an AGP slot then you can go in for a AGP video card; but since AGP has been outdated by PCIe you won't be able to use the latest in graphics technology.
GPU is Graphic Processor Unit. The processor on graphic cards.
SLI/Scalable Link Interface is used to connect two to three graphics cards internally using a SLI bridge connector. Such a setup would use the combined processing power of the GPUs in the cards to render the frames for a single output.
