Are computers capable of remembering..

the order of the cards played, say in a 10 million hand sim? I'm sure they could produce a hard copy of a stream of cards of whatever length, but could memory handle a stream of 25 million cards? My thinking is that if one could play against the same simulated hands using different systems, it might give us better control of/on variance.

If the simulated cards can become a permanent programme against which we can all play whatever system we choose, it might give us a good tool for comparison.
