Well, thanks very much netko for your response. I'll try to look for those cards, and let's see if I can afford to buy them.
Then, I know I have no right to demand anything to Paradox, actually, I wasn't doing it, but just imagine how I feel about this game. I've been waiting for it a lot of time, believing that this was the best game ever, and when it's released I realize I can't play with it because of hardware requirements. I've bought EU1, EU2, Vicky, CK, HoI2, and they were not the kind of graphical monsters EU3 is supposed to be. I've been too much innocent and uninformed, really, you are right, but of course I was not expecting this so amazingly high curve of requirements. But I'm afraid I'm not the only one that is in this situation, and can't afford to actualize the PC often. I really think Paradox is still being the BEST in strategy games, but unfortunately they caught me unprepared.
