You won't have issues.Its a false statement that amd CPUs perform better with amd GPUs.Just keep the card.No need to change.
100% Agree. That's all I've ever run for years. Now there's always a learning curve associated with any new tech toy, but that's what Forums are for. You won't be disappointed, its a great combo together...and get a 660 GTX or better if you can afford it, that's where the screaming begins.
