My network adapter, GIGABYTE PCI G is insanely slow. I updated the drivers to what I believe to be the latest. The driver info in device manager has a date of 2009 though. My laptop is blazing fast sitting right next to the PC.
Should I just upgrade to a USB adapter?

You definately do want GIGABIT ethernet (not to be confused with "GIGA*BYTE*").
This will have "10/100/1000 Base-T" (or just "1000 Base-T") in the specification.
