I have a Dell Dimension 4700 with an added Sapphire Radeon 6450 video card that is successfully running Windows 7, SP1, Home Premium, 32-bit.  Do I dare try to uprade to Windows 10?

I also have a laptop, Dell Inspiron 14R, with 64-bit Windows 7, Home Premium (much newer that the desktop).  Same question - can I upgrade to Windows 10?
