So I have a i7-930, 10 GB DDR3 ram, and sapphire dual-x radeon hd 6970. Whats the bottle neck? I develop mods and stuff for minecraft and I sometimes get as low as 10 fps for a decent amount of time. What could my problem be? I think my power supply is fine, its a 650 watt, and a good quality one. My motherboard is Asus P6T WS Pro, I just cant find the problem. It just seems to lag.
