Triple core, wowza, never seen a CPU with 3 cores, I seen 2, 4, 6, 8, 12, 18, and if you wanna talk Xeon Phi, one with 60+. But I've never seen one with an odd number like 3.
Back on topic, the answer is simply no. You will experience no bottlenecks with a card that bad.
If I'm being honest though, you might want to upgrade your graphics card, or downgrade it. Cards in the 70-90 dollar range don't tend to be good at gaming, and cards that can do free games, or are for multi monitor support can be bought cheaper, just consider that since you can buy a 750 Ti for like 50-60 bucks more and get low settings on modern games, or a 750 for 30 bucks more and do low to medium on modern games.
