There's only one Cray... it's used by NASA and I doubt it's for sale. I do know they sell time to use it... it's the fastest computer on the planet with liquid cooled chips. They use it mostly for testing stress levels on air/space craft in real time 3D environment. I think it's equivelent to a 500 gig hz processor. Your best bet thou, no matter what software you buy, make sure you get the largest amount of hard drive space, memory and processing speed on the market. Also make sure to get the best graphic cards and monitors with as much ram as they can hold, because without it, you won't be able ot use many of the programs available. I know Maya will only work in Window's 2000. be prepared to spend upwards of $2000-4000 just for the computer system to be able to do everything you want. Well if I had a blank check, that's what I would be doing!
