Well, the extra RAM will certainly help. That's a good machine. What I can't tell from that list is how much of the stuff you've downloaded is running... and what version of the OS you have. The more you have of the downloaded software running at the same time, the slower it will be. Each app that runs in the back ground will take system resources. Also if the RAM is limited, as the app gets focus, it may need to move other processes to virtual memory on the HD... a slow process. With more RAM, that becomes less necessary. You should see a good speed boost.
One word of advice... when posting a list like that on the Internet... blank out the serial number. Someone can take that, report the computer stolen... and provides that serial number.
If you lose it... and it gets found. Guess who gets it back? Not you. Or you attempt to sell it someday through a pawn shop... Guess who gets arrested for possession of stolen property and has to prove you own it legally.
Thanks. It is great to be in a community where we can share knowledge.
Oops. Good to know not to post my serial number.
Let me see if I can get an moderator to delete it.
