Computer tech never decelerates.. Every single brand new component of your system may be outclassed the other day.. But graphics cards have a special agility award for that.. (..hmm..sounded weird..whatever..)

If you have the money to buy one piece of component with the latest tech for your system, always go with your graphics card (assuming you are a gamer)..

So if you have the money, of course, spend your whole at the latest tech, according to your question, on 7800PX..
