Geuss The website uses the Intel Ghz.
If the choice of CPU is still open, (Brung???), Its simple get the one that is the fastest on a single core application. I know AMD is not the first choice when it becomes to single core applications overall, but in your case if wanting a 6 core AMD I would go one step higher and get the 1600X (3,6Ghz).
Here in my country we do not have the 1500 6core 3,2ghz only the 3,2ghz 1600 nonX version, so if it will run Woff I can not do any judgement.
When building a AMD rig, do your search on RAM, because the whole new AMD range seems to be very difficult when it becomes to type of RAM.
edit: welcome to Woff, always nice to see an RB veteran.
