I think so and more when you are using a very slow HDD. More memory means less HDD access for the majority of the heavy programs. Where I have seen an evident increase in performance?
1- Browsing the web. When I scroll pages the screen is refreshed a lot faster.
2- Start Menu Opens faster.
3- Outlook works faster refreshing the email preview screen. The inking tool works faster too. I have an image in my signature and the process of inserting the signature is quicker.
3- File explorer refresh folder contest faster. Thumbnail views are refreshed faster.
4- Windows More Maker responds better.
5- Editing pictures is now a lot faster too.
$173 seems to me a fair price taking in consideration how this easy to do upgrade helps with performance. Of course I would have liked to pay less but... I do not regret this buy.
