I just googled "Computer stores in Lincoln Nebraska. You got 10 large ones and around 50 to 60 small repair and retail shops. One of them has to be up to date on clockin and benchin and will maybe let you take your machine into him or her and stuff in the right cpu and load the latest bios. Then stuff your cpu in and check it out maybe do a little benching right there. Maybe make some friends.

I pulled into a small computer store in Portland a few years back. There was a crowd gathered around a computer system. They were trying to overclock for the first time. It a P5N-e SLI with a e6400 chip in it. I got to talking with the group and the next thing you know I was doing the overclocking and showing them around the bios. We got it to around 3650mhz stable.
the store is gone now but we are all still friends. And that system is still in use..

Give it a shot.
