What you need to do is justify yourself m8, could I suggest an experiment to do just that?
Check the FPS when the default flight loads. Shut it down, pop in his PC2100, and check the same scenario's FPS with his ram, then report back the results to.... well, us! ;D
At least then we'll all know whether you ripped him off or not!

I'm not helping am I? ;D
