I have a 6800GT card on an Asus A8V mainboard (socket 939, AGP), running XP
Home.
The nVidia control panel also lists 2X for the OS on my system. I believe
that's normal, although I can't recall the explanation.
My performance (3DMark03, 3DMark05, Doom timedemo, etc.) appears to match
what I've seen published for the CPU/GPU combination.
What's your brother's graphics card? That may be more important than whether
his mainboard supports AGP 8X.
I suggest that you try one of the Futuremark 3DMark benchmarks. Their online
database provides a basis for comparison, although you might do well to
ignore some of the higher numbers. (Some people treat benchmarking as a
sport, and I suspect that some will cheat to "win".)
You might also wish to look at:

"When does Doom 3 Need a Fast CPU?"
(It looks like the Sempron ought to be good for Doom3, but that an nVidia
5700 card won't be the greatest. A 5500 would be worse.)
