I've got a serious problem with the performance of my graphics card, in benchmarks its scoring around 50% of what it should get (based on other users with almost identical setup) I've tweaked everything I can find to tweak and only managed marginal performance increases.
My PSU is only 400w but I cant imaging that thats all it is.

I assume you have an AGP video card. What is the AGP speed (e.g. 2X, 4X, 8X) that your motherboard can support? Perhaps your card can run up to 8X but your mobo only supports 4X.

We'd really need complete specs plus your benchmark scores to help.

Running at AGP 8x

Tried aperture at 128 and 256, marginal difference between the two.

Is your 7900GT an eVGA-brand by any chance? They shipped a batch out with underclocked BIOS.

I would try using a utility, such as PowerStrip (http://www.entechtaiwan.com/util/ps.shtm) to help tweak some settings...

You may just have additional overhead on your system as well -- how many icons are in your system tray?? ;)

Its a 7800GS not a 7900 GT ;) and its BFG brand, identical to my boyfriends card (well almost, mine's the overclocked version) and his gets scores double mine.

4, avg, msn, volume control and nVidia settings
Its a clean install of windows, only got a handful of programs installed.

The card probably requires an extra power connector to be plugged into it. You got that plugged in right?
