PCI Express 2.0 vs 2.1 vs 3.0

[Pablo 54]

Big deal or not? I am considering moving my two 470's to my dedicated folding machine and replacing them with one 6870 or, if i can swing it, a 7870. The card would be for my system in my Sig below (x58 MOBO with a 950 chip). I am assuming I am nowhere near bottlenecking my system.

3.0 8x would be around 2.0 16x. Anything 2.0 8x or 16x would be fine for any of those cards.

I would think going from 2 470's to a 6870 would be a downgrade. I would go the 6950 route much better card. Plus you could mine on the 6950 at 400MHash/s... Just food for thought.

[PP Mguire]

2 470s is in the 580 range. I think a 6950 would still be a pretty big downgrade.

The heat the 470's are kicking off is starting to get to me a bit. Just looking for a cost effective alternative to two jet engines parked next to me a good part of the day. I always assumed ATI/AMD were better on heat then the Fermi's?

the gelid ICY vision coolers work well on the 400 series with the added bounus that afterawards the card is already set up to use a universal waterblock.
