Oh OK. The any 8800 will run Lost Coast fine; I can run it well with my 8600GTS. You should be all set, just ignore the warning Steam gives you. I think I actually got that warning too (except it was telling me my CPU didn't meet the recommended speed requirement of 3GHz or something like that). I am actually thinking those requirements/recommendations were made when the Pentium 4 and the speed race was going on. The Core 2 and Athlon 64 processors feature improved architecture rather than improved clock speed.
