That isn't the point, any modern game that will fill up you're ram over 3.5gb will cause stuttering esp in sli.
"The GTX 970 is a 3.5gb card. It will perform horribly once 3.5gb of Vram is used and is a deal breaker to many high resolution enthusiasts.
However, if you don't run into the Vram cap (1080p, not a AAA fan), then the card is a very strong performer. Extremely well optimized games like Battlefield 4 will run like butter, but I don't see this card holding its value with texture modded games such as Skyrim, Grand Theft Auto, etc.
Overall, I think the 970 still makes sense for 1080p 144hz users and casual 1440p gamers. As for it being an enthusiast class GPU.. well, I guess it will depend on the game. Since you can't see what future games will bring, I wouldn't pick this card up if I were looking for longevity above 1080p. "
