Fit, off topic a bit, but I know you had GTX260's in SLi and Tri SLi, I have been offered a very good deal on 2 brand new Gainward 216SP 260GTX Golden Samples with factory fitted aftermarket coolers that my contact guarentees will do 770mhz, what I really want to know is how well you found they scaled? The reviews at stock I have read show they just pip the GTX295 in most things and I can get the 2 of them for the price of a 285.
My Thermaltake Toughpower 750W should take them with a bit to spare, from what I have read, in systems with an i7 at 4gig and cards on max overclock the load is around 600-650W.
