In that case, would you recommend waiting until I can afford the whole build? Monitor should be good on my current gpu if I decide to get that first right?

I'm looking to upgrade my system soon and due to needing to save a little more for the other parts (RAM pricing amirite?) I can probably afford to upgrade my GPU and monitor right now. I'm hoping to get either a 1080p Ultrawide from LG or a 1440p IPS, I can get either for around the £250-350 mark, my question is would something like a 1060 6GB or an RX 580 4/8GB be enough for gaming at either resolution at close to max @ 60fps, games I play include the witcher 3, gta v and F1 2017. Current specs are: FX 6300, Asus M5A97 R2.0, R9 270X, 8GB RAM, RM850 (Side question, how much of a bottleneck would the FX 6300 be for the newer cards?)

I have a similar spec pc and the same question. Specs are 6300 on m5a97 r2, r9 270x, rm850 psu. I'm looking to step up to 1080p ultrawide or 1440p for gaming with the new build so would I be best served with graphics upgrade first or get the r5 1600 first?
