Most of us object to paying for something, only to find it worth much less a short distance down the road. Unfortunately, you might as well get used to it. You also might as well jump in when you need a system and look at the price an investment instead of an expense.Buy your computer based on what youre going to do with it. If youve never used a computer before, you may not know what youll use it for, so youll have to use your perceived needs and your budget as your rule of thumb. In that case, a good rule of thumb is to buy as much computer as you can afford, and earmark ten to fifteen percent extra because you always end up spending more than you plan.Another rule of thumb is to get the fastest PC you can afford. Computer speeds are measured in Megahertz MHz, and the higher the number the faster the microprocessor runs at least in theory. Theres a lot more to a computers speed than just the microprocessor clock speed like amount of RAM, cache, etc., but its a good starting point.That said, if youre going to borrow piles of money to get a computer, you might be better served with a lease. That way you can give the computer back at leases end, by which time you might want a newer system anyway. Just make sure you can make an arrangement to transfer over any software and files you still need, and dont get stuck with a big buyout: better to give the system back and let the lease company worry about unloading it.Of course, if you can pick it up for a song, it might be worthwhile to keep around as a second system…
