I am the man in charge of the LFS Benchmark site. The site is down due to some system upgrades. Will be back up shortly; sorry.
And yes, I will add the 7800 GT for sure (if it's not already there). If you need to contact me, I can be reached at admkirkSPAMSTOP.at.SPAMSTOPgmail.com.
There should just be an "LFS Benchmark" thread. I searched the forums, and this thread is all I can find that actually has the address to the site. It should probably be stickied too.
