I want to get a GTX 970 so that i won't have to upgrade my GPU for a few years, but i have an FX 4300 and i'm certain it will bottleneck my GTX 970, i almost have enough for a better CPU(along with the GTX 970). If i get the GTX 970, i can save and soon get a better CPU, but i was wondering if i underclocked the GTX 970, would it bottleneck as much? I've asked a few people and they said i could do that but i'm not sure if it would work, or if it would cause any other problems.
