Yeah seems fine to me. Vantage is such a horrible way to bench a system. If you compare it to other identical systems it is fine or if you want to check performance increases in an overclock or different video cards in the same system it is fine.
As jay is saying dont take much notice of vantage, its an artificial benchmarking tool, as such it has no real bearing on your systems capabilities in real world terms. I use it just as jay is sugesting but i always run a couple of game tests as well to get some real world numbers to compare as well.
