Single core Celeron D 430 @ 2.1 GHz (1066 fsb pin mod) vs Pentium D 805 @ 3.3 GHz (667 fsb pin mod). Which will be faster? Doesnt really need it to do anything fancy. Most it will be asked to do will be playing movies at 1080p. Basically if the Celeron D is alot faster than Im going with it. If the Pentium D is just a bit slower then I will go with the Pentium D since it is dual core.
