First, a dual xeon can have as much ram as a quad xeon. However, most motherboards don't have enough memory slots as they are made more compact, while the quad boards end up with a daughter-board that holds the memory, typically up to 16 modules. But as 1gb modules are available today, the Dell I have could go to 6 gigs with no problem. > >The ram won't make a huge difference either way.

Depending on the speed of the program, the size of ram can affect search speed by maybe a factor of 2.0 in the middlegame. In the endgame it will be more pronounced. But since dual xeons can go to whatever memory limit the MB manufacturers choose to design for, this is not very significant. > >A $1800 AthlonMP 2400 system can almost tie the dual-Xeon 2.8 GHz.
