1. Tell your boss the project is in trouble because the Dell does not
have the requisite performance capabilities that is required.
2. If you are the person who specified the Dell prepare your resume.

You are using low end graphics chipsets which share the memory with
the host processor and are less capable than stand-a-lone plugin in
cards.  Why would you expect decent performance when you increased the
amount of data by a factor of four?
