[Closed] Noddy New Laptop Question

Sorry our friendly local computer expert has been inconsiderate enough to go on holiday 2 days before our laptop gave up the ghost.

We need a new family laptop which needs to be good enough for basic CAD work (AutoCad) and which will meet the increasing gaming demands of growing kids (We're not looking for a full on gaming set up but as we are unlikely to replace the laptop in the next 6-7 years its worth planning ahead).

So the noddy question: Is it best to go for a laptop with the best processor you can afford (i7) but with integrated graphics or a slightly cheaper processor with a dedicated graphics card?

Thanks
