I have a gaming PC I built a while back.. considering one of the new RTX4070 or RTX4080 when they come out. Would like to know if my PC will be a bottleneck ... it is Watercooled i7-8700k, ASUS ROG z370 chipset, 32 GB 2644 ram. 750 watt power supply. Just retired and can't afford a total rebuild. ... Currently have a Zotac 1080i Amp Extreme 11gb. Will it be overkill to buy one of the new GPU's? Will performance be reduced in any way?
