I am ready to order very soon a Dell M6500 Laptop for work with Quad core, 6GIGS Ram… the video card is an issue . The primary software that we use does not like the pro or cad friendly video cards. The software we use is for viewing surveillance software of multiple streams of H.264 video. All of the decoding is done at the client station( Laptop ). Dell does not offer gaming cards for this system I need at least 1GB of video memory. The Purchasing department at my company is going to complain if we purchase a Alienware Laptop and I do not want to raise those types of red flags. We are only allowed to purchase from Dell. I can however purchase a separate video card and upgrade the unit after the fact . Is there way to upgrade this unit????
