Im looking at a DELL 17inch laptop, with the WUSXGA+ screen and possibly adding a second LCD onto it. I use my laptop for internet, webdesign, tons of multitasking (lots of windows open at once), trading, and esigna with a few charts open at oncel. I dont play games. Question is: Will the cheaper intel graphics accelerator work just fine or should i plunk down an extea hundred or so for the nvidia or ATI card? will i see any significance in speed with a better graphics card running business apps?
