here's a nehalem writeup by anandtech. Note of interest, hyperthreading is much improved compared to the old days.
They compared performance of nehalem without hyper-threading to nehalem with hyper-treading (the closest you get to a gaming benchmark is Vantage, whose performance increased by like 30 or so percent.)
