Set up my miners to mine Whirlcoin. Working great i must say.
Getting around 130Mh/s on my 280x's and just over 100Mh/s on my 290's..
Although that this isn't very optimal yet, cards are freezing, i had to lower the fans to keep them hot..
So in other words, these can go at least double as fast..
Edit: Getting 150M/s on my 280's now and also 150 on my 290's

Oh yeah,
I can switch between algo's just fine.
I used Wolf his 64bit linux version (source).
