Re: Is an upgrade worth it, or should I wait?
That all depends on you, and the hardware you get. If you get an AMD x2 5000 black edition, it is very easy to overclock it too the 6000's speed, and you save some cash. It doesn't come with a heatsink but you're much better off with one of those gargantuan Zalman Heatsinks. You can build a system these days for Almost any amount of cash, and it wont be slow.
