No; our experience has shown that any deviation from the recommended computer and video card may cause issues that can be difficult if not impossible to correct. Each simulator is tested extensively before being sent to a customer. Through this rigorous testing phase, we know the combination of hardware, software, graphics drivers, etc. will perform as expected. We cannot make the same statement regarding any other combination of products. Because we want to provide the very best experience for our customers, we package the computer with the simulator.
