I would, since you don't have that much to loose, and the driver model didn't change between Vista and Win7.
You can also try and identify the manufacturer of every key bit of hardware in the system, and see if maybe they have Win7 drivers. At least worth a shot.
I am about to buy a new Windows 7 computer. I have to decide whether I want a 64 bit or 32 bit o/s. I will run Office, Photoshop and some not very demanding games along with Media Player. What is the difference? I gather that 64 bit will run faster and according to a post on this Forum dated August 2007 there will be endless problems with drivers. Is that still the case? Any advice would be appreciated.
