Hi all. Tomorrow i'll be placing an order 4 either a hd 4850 ZAR 1300 (rands) or a hd 4670 for ZAR 740. What i need to know is which card would be the best buy considering this card will be running on a samsung crt monitor of a max resolution of 1280 x 1024. Will the cheaper card be able to play new games in at least medium detail and last some time or is the 4850 the better buy?
