I'm planning out a whole new system from scratch strictly for gaming/media. So far I have the whole system picked out and I'm jumping to AM2 unless I hear more of AM3 by January, and I've got a 500GB Caviar for basic storage. What I'm not sure about is if I should get a Raptor to hold XP and games to increase the speed a bit from the 7200rpm of the Caviar (and also if Raptors can use the SATA 3.0GB but I'm assuming they can) or if I should just put the money towards another gig of DDR2 800 from 2x512MB to 2x1GB. Also, If I get a raptor It'll have XP and allt eh games on it and the Caviar will be running Fedora Core, there shouldn't be any problems with that right?
