Infiniband will be a suitable bus for the next 30 years - Intel
The chap had the same problems with the drivers and the stability of the Quad SLI, two 7950 GX 2 cards and it took him some time to place a water cooler on the card. Now it works quite well.
The card overclocked on Conroe platform shows a great potential, and could potentially win all the benchmarks against the competition. We still wait to see the final numbers of the two 7950 GX2 cards in Quad SLI. We managed to make it work in the lab and will hopefully provide some numbers shortly.
You can take a look what the chap did here. µ
