Is there an overclocking database on these cards? I have a recently bought EVGA 8800GTS and was wondering what typical overclocks were. Currently the drivers I am using don't allow separate overclocking of the shaders so I'm doing core and ram only. I have the core up to 650 so far and it runs at 63C while playing the UT3 demo with 15 bots and no artifacts. I was wondering if this is considered a good OC for these cores? I haven't started the ram OC yet, I expect a lot less headroom there though.
