I'm not sure if I chould buy the gigabyte gtx 750ti or the evga 750ti sc. The evga card has a higher clock speed but has directx 11.2 while the gigabyte card has directx 12 with a lower clock speed. I know a card that fully supports directx 12 with have all the benefits but I want to know which one will preform better. A card that fully supports directx 12 bt has a lower clock speed or a card with a higher clock speed but wont have all the benifets of directx 12.
