Okay, don't worry about the receive buffer, that's a minimal issue and won't cause problems which I know about. If you run Vista, it auto tunes the receive buffer, Xp it can be tweaked.
I've also got a Gigabyte mobo with onboard NIC (socket 939). My advice would really be to either borrow or buy a fast newish NIC, which has a few cool features and which you could use to test.
Don't worry about the rcv buffer for now, that's nothing. You could try and set your current NIC to Full Duplex 100Mb/s and see if it is better, auto tune by the NIC makes a lot of errors some times. Just check the hardware properties of the NIC and look through it's options
