Use Google's DoubleClick for Publishers http://www.google.com/support/dfp_sb/bin/static.py?hl=en&page=guide.cs&guide=27854&from=27854&rd=1 along with Adsense to maximise your revenue. Also, place the ads according to Google Adsense Heat Map http://www.google.com/adsense/support/bin/answer.py?answer=43868.
You can make a lot more if you use CPA ads than adsense . There will be no problem about more PV per user though , for sure.... Is it the same forum you are referring to which is in your signature ?
