Fantastic news! I think the multicore and SLI support will solve 99.9% of the performance complaining on these forums. At least it should! Then you'll have to deal with FM/DM complaints from all of the 90 year old BOB vets on these forums, but I'm sure you're used to that.
I'm not sure if the process for fixing SLI support will also necessarily fix AMD eyefinity / NVIDIA Surround support, but I think quite of few of us have sim computers built with multi-monitors, so support for them is key.
Thanks!
