It is really frustrating to figure out if you have enough speed on your cpu for a game. It used to be if you knew the frequency of a cpu you knew it's speed. Maybe that is still true, I don't know anymore. I look at cpu charts and they say core 2 duo is faster than other chips. So I bought a core 2 duo 6300, the most I could afford. Now I found out Cryses will not play on my system because of my frequency speed. Is it better to buy a single core with higher speed or multicore's with lower speed?
