Altcoin Network Hashrate Comparison - anyone know a good website?

[AltCoinSpeculation]

I'm wondering if there's a site or chart which logs and compares crypto coin hashrates

this one has a piechart: http://www.coinchoose.com/charts.php
which lists the top coins as:
1) Bitcoin  2) Litecoin  3) Dogecoin  4) Quark  5) Peercoin  6) Primecoin  7) Feathercoin

but i'm not sure how updated or accurate it is...

thanks if you can help,

ps if there is no website with this info, but you know of a new coin with a large network hashrate of miners, please shout it out
