Help Overclocking a BFG 7800GS AGP

[CaLiGuLa66]

I'm fairly new to over clocking videocards, so i was hoping someone could point me in the right direction. My main questions are:

What's the best utility to overclock? I'm using RivaTuner, but how do i tell if the card is actually overclocked?

What benchmark ap is the best for me to tell the difference between the card at stock settings and then overclocked.

Right now i have it at 450/1325 up from 400/1250 stock. I've seen other ppl w/ this card overclocked much more, but i didn't want to push it as my cpu and system memory are also overclocked a bit.

P4 2.6 running at 2.8 (Presott) 2GB Ram MSI MB (if you could also recommend an ap for detailed system specs, that would be cool)

Any help would be greatly appricated. Thanks!!!

First off, I'm running the 7900GS PCI-E version, but I would assume there's not a huge difference.

I used Nvidia's nTune utility to overclock. You can download it for free from their website: http://www.nvidia.com/object/ntune_5.05.18.00.html It has some very nifty options that it comes with: 1) It lets you monitor temps, 2) It has a built in stress test, 3) It lets you create profiles to run at various times, 4) It's quite simple to use.

Also, it will tell you current clock speeds as well as the temperature. As far as benchmarking goes, I'd just recommend the standard 3dmark06, or any of the in-game stress tests (like CS:S has the Valve stress test).

My card is running at 555MHz core/ 800MHz memory.
