-2% performance actually.

most games don't use hyperthreading, so you'd be better off disabling it and getting more OC from your chip. of course you do get the occasional exceptions like bf3 and crysis 2.

BF3 doesn't "use hyperthreading", it just uses as many cores as the OS sees. This isn't a good thing, because it's seeing virtual cores and treating them as physical cores, which can (and does) reduce performance.

This is true, games are and probably will be for years to come, core dependent. Try looking up the issues people have with choppy BF3 gameplay due to hyperthreading. Chances are this is because with hyperthreading it breaks up a logical thread into 2 virtual threads, that both share the workload capacity of the single logical thread. Now you have 8 threads doing all the work at half the power each logical thread should be. While this splits up the workload for many applications to accelerate them by supplying more "horses" under the hood, it would seem to me it would damper gaming performance as each "horse" is missing 2 legs. For gaming you would want each thread working at full capacity, this is why the i5 2500k beats out the 2600k in gaming benchmarking with its 4 logical threads versues the 2600k's 8 hyperthreads. To make it more understandable in short hyperthreading splits up the workload among 8 threads which work at half the capacity, so when a thread completes it can move onto another task instead of just 4 threads being bogged down with tasks lined up waiting to be executed.
