thanks for the reply guys

well the budget is anything we can justify, if we think having the more expensive over the other would be better and can justify it then we can use it. of course bang for buck is something i'd take into consideration as this homework is supposed to be for a real company which would need to consider cost.

the sort of programs it will be running is maya, renderman (is this a plugin for maya) and eyeon fushion 5.

the last post was great help much easier knowing where to start and then what to go to next.

thanks again
