I would like to ask if the shaders mod would run smoothly on my minecraft if I bought a video/graphics card called NVIDIA GeForce GT630 4GB? Now with optifine I am running minecraft at approx. 30-45 FPS and without approx. 15-25 FPS. My goal is to keep the FPS above 60.

MY SPECS:

CPU: AMD Athlon(tm) II X4 645 Processor
RAM: 3.8
OS: Microsoft Windows 7 Home Premium Edition Service Pack 1 (build 7601), 64-bit
VIDEO CARD: ATI Radeon 3000 Graphics
