Recently built a new PC with a ROG STRIX-GTX1070-O8G-GAMING graphics card. Ever since I built it games that run with UE4 have kept on crashing. Tower Unite and PUBG being some of them.
Should I be worried if i have got a dodgy GPU? or is it UE4 playing up?
Hmm, do you get those crashes just with UE4 games? (have you tested others)
Take a look at the log files from the games, probably you can get some useful information from there + report those crashes on the game specific forums
