Hi Jeff,
Thanks for that info about the Gateway computer. It seems good with its graphic card slot however the article suggested there may be not many graphic cards capable of being fitted.
Not many replies so far to the posting so I guess it may not be possible to upgrade our HP's.
There appears to be a market for this type of add-on/peripheral to laptops. I like working on a laptop for ease of taking to clients, plugging things in, desk real estate, etc. I think however they should be more flexible with the ability to upgrade. It may be back to a PC for the next machine. Some of the graphics cards are getting sophisticated with their own memory and quick application.
