I am not sure how it will run on a high end machine, but don't try it on a computer that only meets the minimum requirements. I installed Act!2005 on a 400mhz machine with 256meg of ram. The program is so slow it is useless. Over 3 minutes to start program, over an hour to backup. Unusable while on the phone with a customer... Too Slow. It is one of the most dissapointing upgrades that I have ever purchased.
