Hi. I'm looking to upgrade my computers graphics card but dont want one so powerful its being held back by other components. My motherboard is a ASUS Z97-A and my CPU is a Core i5-4690k and I have 8GB of DDR3 ram running at ~950MHz. My current Graphics card is an EVGA GTX 960 2GB. Would a 1650 or 1660 be too powerful for this build? Many thanks in advance.
