I just got a new Graphics Driver from a friend... for free :D. Its a ATI Radeon™ HD 4670
How do i know if its compatible with my computer?
That's not a graphics driver, that's a video card (otherwise known as a GPU or graphics card).
The driver is the software that controls it.
Well, post a picture of it. They are the last card that could be AGP instead of PCI-E fitting. I'd also like a picture of the inside of the case and the sticker on the big box in the corner of it with all the wires coming from it (the PSU).
That should be enough to determine.

Get that, if your PSU is above 500W and good quality. If it isn't, then upgrade PSU. :P
Should I install the wireless adapter after I built my computer?
Either or, but I'd do it after just in case the extra driver install somehow confuses something.
