I plan on getting a GeForce 4 Ti4600 as soon as the FX comes out and the Ti's price drops (any advice on brand, PNY, Extacy etc. is appreciated) and need a little help on choosing a good sound card also. Getting everything from newegg.com and hope I'm not getting ripped on any prices.

Thanks for y'alls help.
