3xhd5870 is best config. (you get near same as 2x hd5970)
if you take 2xhd5870 instead of 1 hd5970 you havent so mutch temp problems, you can run it with 850 mhz arround the clock..
we have many many died hd5970 but no hd5870.
you get more power and mutch more stable system with that hd5870 cards.
but isnt it a bit too late to start sl3 unlocking? |
