The thing is, the hit is not that huge with a NF2 board if you are running dual channel because two the DDR DIMMS provide way more bandwidth than an Athlon XP can utilize (an 800MHz FSB P4 is a different matter entirely). The dual channel architecture of the NF2 chipset was basically designed JUST for the purpose of allowing both the CPU and the IGP to have adequate memory bandwidth. In fact, with NF2 SPP boards with no onboard graphics, enabling dual channel raises the memory performance only about 5-10%, which translates into maybe a 1% overall system performance increase. Every review and benchmark I have read, including the link above, indicates that the NF2 has bandwidth to spare. Heck, even running both integrated video AND sound doesn't seem to drag the system down by any amount that can be easily perceived by the everyday user.
That said, a cheap Quadro card might be a good choice for your brother because it has special optimizations for AutoCAD and other professional Open GL apps that can be unlocked with the Powerdraft software at nVidia's website. The Quadro core has special features such as hardware anti-aliasing of wireframes that make them nice to workstation cards. ATi has a similar card called the Fire GL that is a bit cheaper, but seems to have equivalent features. I haven't tried either of these cards, though, so I can't say how well they work in real life use, but they could be useful for your brother. These professional Open GL cards do cost about double what an equivalent gaming card would cost, so I'd try out the NF2 IGP and see how that works for him before jumping into one of these guys.
