I have been looking at replacing my graphics card because that seems to be my main bottleneck. I found a GTX 750 Ti that seemed to have a good price for the performance to add onto my desktop. I currently have a AMD A6 APU processor with onboard graphics, installed in a ASUS F1A75-V Pro. I have another graphics card, a ASUS Radeon HD 6450 1GB installed that the GTX would replace. The GTX would preform better than the onboard graphics and the 6450 working together if I'm not mistaken, but would there be an issue with the GTX not being a compatible card to work with the on board graphics?
