Edit: Seen a guy last page with a 7800gt that got 7200 which I believe is high for not being oced although it may have had higher clocks than yours when he bought it. Most benchmarks I remember got about your score with the 7800GT, although you may wanna make double sure all backround programs such as Anti Virus stuff is shut down, latest drivers downloaded, and your settings is all performance so there is no AA or AF or anything.
