E1505 6400 ati driver versions

Don't know if you are still looking for an answer to this, but thought I would try anyway.

Drivers are updated for a few reasons, but these reasons are primarily to fix an error that prevents the hardware from working as it should, to add support for newer versions of the hardware, and rarely, to add a capability that wasn't contained in the previous release.  If your hardware is presently operating as it should with the driver you have, there is no need to perform the update.  The fact that Dell has an older version of the driver means very little; Dell will release newer versions of a driver for as long as the computer they are used on is in production.  The updates generally stop when the driver revisions cease to provide a positive improvement (especially in laptops since these are rarely upgraded once delivered), or when a newer model replaces the computer in question.

In practice, the most common reason for releasing new versions of the driver is to provide support for newer versions of the hardware.  If you have a desktop and replace the video card, it would be silly to not use the latest version of the driver.  It could also be irritating since the driver you have may not support all the capability in the card.  With a laptop this is unlikely since the video cards are practically hand made specifically for a given laptop.  Your only choices are from the cards that Dell decides to offer with the computer, and Dell almost never issues an upgraded video card after a computer enters production.

In deciding whether or not you need a new driver, keep in mind that drivers are software.  They can also introduce problems as well as cure them.  That is why Windows has a driver "rollback" capability.

Thank you "JackShack" for your reply. I was indeed still looking for an answer.
