In other games, I find that although a I may drop down to 500mhz on the core in menus(3D low), I'm right back up to 591(3D high-OC'ed) when I go back into the game. HL2 tosses me from 3D high to 2D low while playing the game! Time to look for another patch. ;(
I'm running on an older system so no BIOS upgrades left for me, but I suggest you hunt for a BIOS update for your mobo, from what I've read around the net a BIOS update for the 78xx series seems to fix a lot of problems. Chipset updates are also high on the list.
Depending on who made your vidcard, there may also be a BIOS update for it, I know eVGA has Bios updates for some of their 78xx series cards.
As for opening up the hidden settings on your card, I use NVTweak: http://downloads.gur...oad.php?det=911 for those, and overclocking, and RivaTuner: http://downloads.gur...oad.php?det=163 for monitoring. Only use one utility to overclock, not both at the same time. It's fine to OC with RivaTuner, provided you aren't OC'ing with NVTweak at the same time. I use NVTweak for the OC as the GUI is a lot more friendly, RivaTuner takes a bit to get used to.
Tons of drivers at guru3d.com too, pick a flavour. Also, after uninstalling drivers, reboot into safe mode and clean up the garbage left behind with Driver Cleaner Pro: http://majorgeeks.co...onal_d3214.html reboot, then install the new drivers.
Hope that helps a bit.

A quote from a mod in the eVGA forums, about a 7800GT CO with your prob: "Also, chech to make sure that Your Graphics Card is on its own IRQ and not sharing an IRQ with another Componant. Also, what Main Board are you using? If it is ASUS then set Your PEG Link Mode to Fast, or Fastest, and then set the PCIe Frequency to 125.MGz."
Hope that helps, thread can be found here: http://evga.com/comm...?TOPIC_ID=10268
***EDIT*** BTW, I agree, your card should be kickin butt without OC'ing it, mine is a wee babe compared to yours, I have to OC.

If you can't find it, let us know what the exact model of your mobo is, we'll hunt that info down for you.

For the PCI-E frequency, select "Jumper free configuration/PCI Express clock", and then set it to 125.

The fix? Asus A8N motherboards are still coming with the 1008 bios. Update to the 1009 bios (if you're really feeling brave you can try the beta, but I would wait). All I can say is this is what made a big difference for me. Damn smooth now. I'm not finished messing with this thing though. I think there's alot to be found yet but I want everything to be running smooth and stable at "stock" settings before I start messing 'inside' the bios or with the graphics card (still looking for the VGA bios). So far I'm not that impressed with the nvidia NF4 chipset but I have hope.
Use the Asus Update tool. Download the appropriate motherboard bios to a folder and direct the update tool to there to flash. Don't bother trying to get the tool to download the bios itself. Other than that it's fool proof. Don't be intimidated by it.
Once again, I think it's very important that you have all the latest drivers from Asus or nVidia (chipset, graphics etc...) and an updated bios before you start messing with anything else. You shouldn't have to be resorting to tweaks to get HL2, definitely HL2, to run smooth at it's default settings. Now a game like F.E.A.R. is antoher matter, that could bog down the best of rigs.
