@OP, wow I just bought one of these PB328Q too! I absolutely freakin love it. I pushing it with two 970s at the moment. Your sentiments about it are exactly mine. I just cant wrap my head/eyes around the curvy screens and they are only 1080 anyway. I love the big screen.
You can get a EVGA GTX1070 for about 377 right now. That's not bad man. Good Luck with your final decision.
