(*&@#%&* forum software lost my walkthrough. Now to type it again.
The easiest thing to do, really, is to use aquamark/3d01/3d03/3d05/Heaven/spi1m/spi32m/wp32m/wp1024m/pifast for your ten benches and skip vantage and 3d06 entirely, or buy 3d06 (It's $5 or something along those lines) and dump aquamark from that list.
Beyond that, here's the procedure for submitting, with flavors for benchmarks that show the score and benchmarks that don't.
1) Run the benchmark.
2) Get the score, if possible make sure the main benchmark program window is showing, with the resolution and such. Move the result window so it doesn't obscure the resolution/etc. Hit the "details" button if there is one, and put that window somewhere, again not obscuring the important stuff. In the case of Vantage, the web page is your details window and you'll need the score and the link to be visible.
3) Open CPUz, then open CPUz again and select the "memory" tab on the second one. Arrange the windows somewhere.
4) Open GPUz, put that window somewhere too.
5) Do a general window reshuffling so that everything can be seen, this can be tricky at low resolution.
6) Hit printscreen, save the screenshot.
7) Fire up HWBot.org, hit Submit Result (right side, orange box). If you don't have an account, create one and select overclockers.com as your team.
8) Select 3DMark Vantage from the poorly designed list.
9) Start filling in boxes, the CPU/clocks and GPU/clocks are mandatory, as is the score box. The other stuff is optional, I like to put the memory and the motherboard in there at least.
10) Towards the bottom of that page is a Validation section. Feed it your screenshot in the screenshot section, and then copy the link from the Vantage webpage ("Link to your result" box) into the link for orb validations or validation link or whatever it is.
11) Hit Submit and throw a party!
It looks complicated in text, but with a bit of practice it becomes quite quick and easy. Once you have a submitted result there's a button that fills all the cpu/gpu/mobo/memory/etc. data in to your current submittion from a prior result. Very handy.
