[Tutor] python, speed, game programming

[Keith Winston]

Truth in advertising: I just realized a Core I7 only benchmarks about 10x
faster than a Core 2 Duo, using Passmark. Wow, something like 6 years newer
and only 10 times? Anyway, I'd STILL expect to see some of that in the
program performance, though maybe once I get it ironed out it will be a
little sleeker...
