Seems a very reasonably chip still
Lets face it, its going to be very unusual workloads that will tax 4 cores, let alone take advantage of the 8 cores you get with hyperthreading. (Database servers, Well loaded Web Server - the only desktop task i can think of would be video rendering)
It seems these are likely to be dual rather than triple channel DDR3 - guess we'll have to wait for benchmarks to see the performance impact there.
If its a bit cheaper than the I7, it could well be a winner. I've been holding off on upgrading (Lets face it, core2duo / quad have been looking like old designs for a while now - how long have AMD been free of the front side bus?)
