It depends on what you're doing. For regular day to day tasks like web browsing, email, word processing, etc, it makes no real difference. If there's even a small amount of gaming involved, the actual video card will win hands down every time.
I have an ASUS P8Z77-V LK mobo and am using an ATI Radeon HD 4600 Series video card. Am I better off using the iGPU or the Radeon card? Which is actually easier on the system? I have been using the card, but I always wonder if I would be better off with the iGPU. Thanks in advance for any answers to this question.
