"For the most part, more is better. But the thing about this equation is while more is going to be faster, does the extra speed warrant the price increase that is going to come with the upgrade? - The release of the X58 chipset saw two new standards for memory capacity; because of the extra module included we now see memory kits in 3GB and 6GB.
If you didn't have an x64 bit version of Vista, you were only using around 3GB of your 4GB memory kit. But even this yielded some pretty impressive performance increases over the 2GB kit, which makes us wonder; with 3GB kits being a standard for X58 systems, is that more than enough memory to keep one satisfied?"
