My old card, evga gefore gtx 650 1gb,Is getting old. And now i want to improve and buy a better card because i wasnt as satisfied from the old card, So i went to the store and asked the seller about a card, And i ended up buying Gigabyte gefore gtx 750 2gb. Will i notice any difference from the old card? is it a better card by far or should i change into something else?
