Im Currently looking into buying a gtx 980 ti but i dont know what is the best one i am running it on a 1080p monitor at 144 hz. I am currently running with a evga 970 ssc and i love using evga precision x and i use k boost, if i get a different manufacturer can i still use the k boost option. Thank you. And also i have a 750 watt PSU would that suffice with a 980 TI
