Firstly - you don't need a decent "comp" to take good screenshots
Secondly, theres no way of telling what you want me to screenshot
Thirdly - It's a laggy demo server full of mainly wannabe drifters who only seem to spin. Smooth photogenic material if i ever seen it
I took a few pics, but there was nothing that good in any of the replays - you get close, and then hit him. Obviously Keyboard Stabilised perhaps isn't the best idea for drifting...
EDIT - Seems that the files came out larger than i intended. Oops.
As Jakg says, you don't need a good computer to take screenshots. As the shots are static no one can tell if you have a crappy framerate, so just pump all your graphics settings up to the top.
