Re: Are you going to buy Fermi?
No chance. Right now my GTX 285 is just about hanging in there, but the cost of the 4xx range, combined with the power requirements and sheer heat produced makes them very unattractive.
It's possible nvidia will refresh the parts in the next 6-9 months or so, reducing power usage and maybe increasing performance a little, but by then I'd imagine the 58xx refresh to be out to counter that.
When I find my GTX 285 doesn't cut it any more, I'll more than likely be buying a 5850 or 5870.
I'd also been considering a second GTX 285 instead, but would require a stronger PSU as well as the card, so whilst it might be a little faster than the 5870, it'd cost just as much total and use more power, thus producing more heat.
