I need to try FSO on my laptop sometime, which has an integrated R9000 mobility 32mb (total POS; slow, buggy and non-upgradeable, but the ISTS prize computers were strangely business models). I never got around to trying it since the desktop's 6800GT runs it perfectly but it might be interesting to see if the problem occurs with the laptop drivers, which are different from the normal catalysts. Of course, I get all kinds of other image corruption issues with it in other games, so I'm not expecting much.
BTW regarding processors, here is something that has me sort of confused. Since the Opteron 150 is exactly the same as a 940 pin FX53 but with a locked multiplier, why does it cost like $250 less? At the moment it seems like a great deal even if the slightly higher prices of a 940 motherboard and registered memory are taken into account.
