I'd go with the Blizzard 060, the difference in performance is like night and day in comparison to an 030. I already have one of these and it preforms even better than my Blizzard 060/PPC board...

And at that price I'm seriously considering purchasing one myself thats a bargain price compared to the prices on ebay that these boards go for...

It's also safe to upgrade the Blizzard to 60Mhz for even better performance...
