I am choosing between the 21.5 inch 3.06 GHz base model and the 21.5 inch 3.2 GHz model, the only games I will be playing are flight sims.......x plane 9.....x plane 10 when it arrives and maybe use windows to play some other games. Will the 21.5 inch base model allow me to play x plane 9 with all graphic settings set to the highest level or would I have to buy the 21.5 inch 3.2GHz with the bigger graphics card (512mb) to do that? any advice would be great! thanks,
