Could be, but that score is an awesome score, SLI systems with FX-57 CPU's only get like 12,000 so you're score is fine.
Plus don't worry about benchmarks, seriously if you spend all your time worrying that you scored x number of points below someone else's 'similar' system then you'll never really appreciate your computer. My computer is a heap of junk compared to some systems, but I don't worry about that, I'm just glad I have it.
