Hhmm seems like overwhelmingly, the 270 is more popular.  Have you guys seen the new version of cudaminer, puts out 300-320mh/s, but hhmm you think 480 for the 270?

Would 3 of these running plugged into mobo be a heat issue?  Kind of need it stealthy (size wise, not really noise), so just gonna use a gaming case filled with fans.

I got this mobo, http://www.newegg.com/Product/Product.aspx?Item=N82E16813128594

and already have a 1500w PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E16817256054)

My original plan WAS to go with 270 or 280, then I heard about what the 750ti could now do, so I started re-thinking.
