I put in my CPU, an i5-4690K, 4 Core and started looking for compatible GPUs. Does this look right so far? If so, what do you think I should go for?

I suppose what I'm asking is, do I:
A. Push my current motherboard and CPU to their limit with the best GPU I can get for it, or
B. Sell my rig, put that money towards something brand new. 

I'm new to the hardware world and worried that I'd fuck up majorly, which is the main reason why I've kept the same specs for all these years.
