If you're seeing screen tearing, you're probably not actually running 144hz. While the monitor supports 144hz, your connect to the monitor must support and be configured for 144hz.
Don't confuse the guy. It doesn't matter what your refresh rate is, without v-sync, games tear.
I wish I had a 144hz monitor to try out with, just stuck with a standar 60hz LCD, but back when I had a CRT, going from 60hz to 75hz dramatically reduced perceived tearing, then alter going to 85hz made it very very minor. I can only assume 144hz makes it near imperceivable, but I could easily be wrong.
Unfortunately, I really need to upgrade my memory, which requires upgrading my motherboard, so I might as well get a new CPU.. no money for a new monitor right now.
