All this talk about max/min/avg fps is really no use, imho, if the parameters are not clear and probably different for each person posting here. So, in order to really compare fps, I'd suggest to follow the link given by Moonclaw a few posts up, run it on your machine and upload it to the LFS Benchmark site. Than you can compare fairly well how your system compares to other similar systems.
Just my 2p.
