I have just installed a Gainward Geforce 680GTX 2Gb, but now I believe I should get the one that has 4Gb for a little more to pay. The question I would like answering is will I have to re-install all the drivers for the new card, or can I just swap it out with the other card since they are the same cards all be it that one is 2gb and the other 4gb. Thankyou!!
