Buying a new laptop, I have worked down to 2 choices. One has Win7 (32-bit) and 4gb DDR2 ram, the other has Win7 (64-bit) with 3gb DDR3 ram. Same price. I don't really know enough about the difference between 32/64bit or DDR2/3 to make a decision. Can you explain the difference and offer advice as to which is best. [more inside]

I want to upgrade my pc's memory, but I noticed 6400 is the same price as 4200, and I can use the ram to in a faster system later. Does faster ram (400mhz) 6400 underlock to (233mhz) 4200? Gskill has 2 gigs for 187 on newegg, 5-5-5-15, why my system ram is ddr2-4200 4-4-4-12.
