Well Intel and AMD have come up with "dual core" processors which will increase the processing capabilities of computers.
I expect over the next 6 months there will be a RUSH to produce programs that take advantage of this speed. Unfortunately, in their rush to get something to market I suspect the programs will be poorly written, try to be everything for everybody and be a real dog to run on non-dual core processors.
Look for a Quickbooks upgrade in 9 months. ; >)
