As we know, Core i7 processors may prepare quite a few surprises in games for us. The major one is not very high performance of Nehalem based processors. However, the increased clock speeds help improve the situation here. At least, Core 2 Extreme QX9770 is no longer the fastest gaming CPU out there, Core i7-975 XE has every chance to contend for this title. Especially, since we know that disabling Hyper-Threading technology should boost the gaming performance of Core i7 platforms additionally.
It is a great example how a new technology, which Intel introduced as a major advantage of their new microarchitecture, may actually have a negative impact on the performance. Luckily, there are only a few gaming titles where Hyper-Threading causes serious performance drop.
