It depends on what yu are expecting. The graphic card will only accelerate your preview, and not really affect your rendering at all.

Your processor is ok, and should handle renders fine, but if you do larger format renders with more bells n whistles on, that will increase render time dramatically.

Some people expect high quality complex render intwo minutes, and that's just not realistic.

On my athlon 3400+ system here, without all the bells n whistles on, and a full screen 1600x1200 render, I can easily wait 15 minutes for just that. Course, you might also upgrade your system in the coming year, and that would decrease your renders times.

Way too many people take way too many things way too seriously.
