Upgrade to solidworks 2007 software

Hi guys,
I am currently using SolidWorks 2005 which is working fine, but I would like to upgrade to a newer version with more updated features that can aid me to become a better designer.
Will a newer version require me to upgrade my graphics card for a better experience?
Will it have features such as the ability to access SolidWorks explorer functions from windows explorer and the new expert tools?
Please assist.
If you can please tell me how I can acquire a more recent version of this software preferably Solidworks 2007.
