I personaly leave my computer running 24/7 for weeks at a time. I can get up to 7 or 8 gigs of use not running any games or production software. That is just web browser and messengers. So yea any one that uses a 64 bit OS can benifet from having more than 8 GB of RAM. Windows 7 is one of the best Microsoft OSes to date, though it still has many issues and holes in it. The more resources you can throw at it the better. It is true that processor speed is a big deal, but with so many compines following suite to Adobe and multi threading it that is becoming less and less of an issue. What once took a 3 Ghz minium to run now only takes a 2.1 and across two or three threads. This is going to start getting really huge and manditory soon. Now that Intel is getting close and AMD has already droped out octicores and decacores, software compines are getting with the picture and making things multicore friendly.
