Ok thanks for advice. Thought that was my situation with other hardware slowing it down. Will be looking into new motherboard and CPU.
Depending on your budget you can go low budget with an AMD dualcore or go high with AMD quadcore/DDR3 RAM. Personally, I'd go with AMD for the value. But if I had to go Intel, an OC'd E8400 and a P45 chipset mobo could max out what your GPU is capable of.
