I mainly play on xbox but I want a pc that can run games on a 144hz monitor if I wish too as well as generally being fast. Games I'm thinking of playing are GTA 5 (doesn't have to reach 144hz, 60 would be fine on here) as well as games I wish to play in the future that I can't get on xbox/playstation. I also play RS3 and OSRS but they're less demanding so wouldn't need anything specifically for that. I don't have a set budget but I'd want something that would last and be useful for a number of years to come if possible. I'm currently running a gtx 970 which is now over 5 years old.
