A better CPU ABSOLUTELY WILL NOT affect your performance in a game. It doesn't matter whether it is a 2.0Ghz processor or a 2.8GHz processor, your performance will only be affected in one game, and thats BF2. But it sticks out like a sore thumb because in no other game will you get any performance increase. Thats because the videocard will keep your bottlenecked. The videocard can't keep up with the CPU, so the only thing you can do is get a better videocard. Stick with the 144, and if you need any extra muscle, overclock that puppy to [H]ell. Invest the rest of the money in a better videocard.
