Is it still worth useing the old version? Also is there a realse date?
You can use the old version, Vantage is still used heavily, just not DX11.
It looks like you want a nice scoring benchmark that everyone will you use at certain presets, and if thats the case you will probably have to wait for 3DMark 11.
If not you can use the settings that most people use for Heaven and compare, as that seems to be most used, and the most popular.
