I've currently got a GA-Z97X-Gaming 5 motherboard and was wondering what my best option is for a gpu upgrade. I'm rocking the gigabyte gtx 970 but I'm itching to upgrade to a new card that will work well with my old motherboard. I'm no expert on building computers so I figured I would just go with the most powerful card I could afford until a friend of mine stated that paying for a card that is too powerful for my mobo would be a waste. Basically, I'd appreciate if you could inform me on what the best choice for an upgrade would be based on my motherboard. Thanks.
