| First, if you want your viewport to be smooth, get a better graphic card. Personally I'm using GeForce 6600GT 256MB but it can only handle around 1 million polygons without serious 'lagging'. If you want to increase your rendering speed, you need to have a better processor and more RAM (for software rendering). If your renderer is set as 'hardware rendering', you need to have a better graphic card because hardware rendering uses your graphic card to do the rendering, while software rendering uses your processor and RAM.
I will recommend you to get at least 2GB RAM because you really need that very much when you are rendering a scene. But if you feel that your viewport isn't 'smooth', then you only need to get yourself a graphic card and not RAM because RAM will not make your viewport smooth when you are rotating/zooming. But don't forget, you must make sure your processor is 'strong' to support all those things, if the 'bottleneck' problem comes out, its just wasting your money to buy all those 'upgrades' since the processor cannot handle all the things, only part of them are used.
