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...
