The hardware you are editing on can make all the difference when it comes to rendering a piece you have spent hours on, if you are using an Intel Pentium 2, windows 98 based computer or and Apply Imac G3 533MHz or similar you may have problems with speed and stability during output and rendering.
I'd recommend that you use a system that has a newer processor (pentium 4, centrino - maybe, any duo or dual core processor) running at at least 1.7 GHz, and a newer operating system either Windows XP or Vista. In my opinion XP is far better but as time goes on Microsoft are adding to the features and fixing the bugs in Vista, so maybe it will overtake XP in months to come!
However if you're using a mac then I'd recommend that you have at least a G4 but my personal recommendation is a MacBook Pro or a newer iMac.
As far as RAM goes I suggest at least 512 MB ram (256 will do in most cases) but basically, the higher the better.
Dell systems are probably your most cost effective windows systems you can purchase at the moment, also be sure to check the PC World website from time to time, they have good offers on computers and laptops most of the time.
