Hi Douglas, It's best to contact Duxbury direct where confirmation of pricing is required. Although prices are on the web page. However, looking at the URL you supplied, I'd say any of the Windows 7 Pro systems will be OK, though it would be wise to upgrade DBT. DBT does not put a major strain on processor or memory, although the faster processors are obviously generally better, and a minimum of 4 MB memory is good, which would be the maximum with a 32 bit processor. DBT will also run on 64 bit systems where you can also have more than 4 Mb of memory too. George.

Please advise the cost for this update if necessary, as well as the hard drive size, memory, microprocessing speed and number of bits required for DBT.
