Not necessarily; but you may see an improvement using a better DVI cable - price is not an indicator of improved quality.
Lindy offer two (maybe three) grades of DVI cable so they obviously believe there are differences.
I tend to favour 'oversized' DVI cables built to higher tolerances - see
http://www.bettercables.com; though others argue all Digital cables will produce the same results.
Best to organise a 'Home Loan' if you can - saves making an expensive mistake.
