I am building a new system and have almost decided on the Matrox G400. I do a lot of word processing, photo and poster work, but I also play a lot of games, although I am not into it seriously. How noticable is the lower gaming performance of the G400 for someone that is a casual player like me? Is it VERY noticeable or do you have to look close to see the difference? I have heard the G450 isn't much of a improvement, anyone heard if there is something better comming soon that I should wait for? THANKS for everyones time!!!!
