No, it won't have. It will be fine. I'm all for performing a clean install of drivers when it's necessary, as seen at my tutorial here:
http://www.tomshardware.com/faq/id-2767677/clean-graphics-driver-install-windows.html
But I've changed out maybe fifty to a hundred cards that were all based on the same architecture, using the same driver packages, and never once did they require reinstalling the drivers unless you were moving from one gen to another, or from AMD to Nvidia or reverse.
I'm pretty sure we've had some disagreements in the past regarding bad advice, and once again, I think this is another case of that. However, I suppose there is nothing wrong, actually, in doing a clean install of the drivers EVERY time a new card is installed. It's just that it isn't necessary in THIS or similar cases. If different driver packages were called for it would be a different story but there is absolutely no sense in reinstalling the same drivers you already have installed unless there is currently a problem and drivers are suspected.
