Two GTX460s are comparable to the 5970. Your 3.8GHz CPU will be weaker than the OCed E8400 @ 4.4GHz due to the 600MHz difference and 3mb less cache. So if there are bottlenecks for the OCed E8400 + 5970, there will be greater bottlenecks for your system.
So my CPU will definetely be bottlenecking my cards. In this case would it be worth it to upgrade my processor? I am kind of limited in my upgrade path since i am using a socket 775 mb and upgrading it is out of the question.
Well the games i mostly play now are WOW, SC2, and BFBC2 so i dont know how my e7400 would perform in those games with the 2 gtx460s. I don't live near a microcenter, but i will look on ebay and amazon and see what i can find in terms of quad cpus.
