Recommended PC Specs

Bigger/faster processors, RAM, and drives will get you improved performance, but Apple aren't offering example mid or high range specs, only the minimum requirements. Compare with the system you'd been thinking of and see if it might be prudent to increase the RAM for example. I would think that a system with 512Mb is going to be awfully slow for example, constantly using virtual memory.
