NV is currently "giving away" the card for $640. Yes, the kit is meant for scientific polymer-folding problems for which an "extreme" gamers-box is little better than a 6502.
Yep, *nix is not for everyone ... tho my current amd5400+/DDrake_6.06 system has performed effortlessly and without issue for 2-y. OO handels my lectures, GCC my code and U-Tube ... well, I can watch "muski" fishing videos just fine.
I agree...its for a specific segment of users. Its like reading all those forums of people finding the msot expensive cards and yelling "I'm getting one of these to play Quake 3 with!!" ...buddy, that's a Quadro/FireGL card...not meant to game with...
So, yes, I agree, it has specific purposes...just dang expensive, but I'm sure worth the cost for those using it. Good luck...get it while the 'sale' is on.
