I've decided to go ahead and upgrade, now, this has probably been asked a trillion times, but. I cuerrently have a Celeron at 2.8 ghz, I found a great deal on a Athlon64 3200+ at 2.0ghz. Will this perform better than my celeron.Also, i want to be able to play all the new games, like Half-Life2. Will this processor be good for me?
