i own an i5 4690k and a gtx 970 and as of the past year one of the fans has been getting progressively noisier due to a fan bearing, i was considering selling the card on ebay to someone who isnt really bothered by it for maybe like £180 or something and then buying a gtx 1070 but after seeing that the card isnt utilised fully in bf1 with the cpu as the cpu remains around the 90-100% range and the card remains around the 80%-90% mark i can only assume there is a bottleneck, my i5 is oc'd to 4.5 ghz and i was wondering if the improvement would enough in performance in a majority of games to justify purchasing the card. ive seen posts on here with replies saying it doesnt but bottlenecks really annoy me XD (btw gtx 970 is out of warranty date). thankyou for any help guys
