Hyperthreading, does it help gaming now?

If you already have the knowledge, then why ask eh?  

Yup that seems to be the case, games are starting to use more cores, although more slowly. That's the reason why modern dual cored Intel chips got knocked out by the ancient Athlon and Phenom II x4 chips in the $100 and below CPU segment (Toms hardware, Best gaming CPU's review, Feb 2013), because modern games like more cores  

I also read that an FX 8350 performs slightly better than an i7-3770k in the latest Crysis3 game!!!

Now that both the PS4 and Xbox will have 8 weak cores, game developers will be forced to spread out across more cores, no matter how difficult that maybe. End result; significant advantage to AMD cpu's 2-3 years down the road.  

I don't know if my knowledge is correct thats why I ask and untill recently I thought HT had no impact on games at all.

For the most part you won't find many games that will get anything from hyper-threading. While there are few that may get a performance boost out of it in most cases they are going to be heavy multi-threading applications that would do better with a full core to run over the hyper-threading.

I think Hyperthreading mostly helps the dual core chips since more modern games can take advantage of 3-4 cores now and the i3's are 2 core, 4 thread chips. The benefit isn't there for the i7's because they already have 4 cores to begin with.

No.

But benchmarks done over the past several years have shown that when Hyper Threading is enabled, it generally causes an average drop of 2% in game performance.

Recent benchmarks, however have shown that hyperthreading does help the core i3. Hence why the Athlon II X4 and Phenom II X4 are back on the list for best gaming CPU's for the money and the Pentium G's are off the list and the i3's remain.

it depends on the game but in most cases it reduces cpu performance per thread by anything from 2-25% which basically means an 8 threaded cpu will give the same gaming performance as a 6 core cpu that doesnt hyper thread.
on some games hyperthreading can decrease performance of the game if its badly optimized, as it will use 1 core and 2 threads instead of using 2 cores with 1 thread each.
running 2 threads off a single core means the cpu resources are shared and every time you share something you get less of it. but the amount will vary depending on what threading needs to be done. a well optimized engine will gain form threading while a badly written 1 wont.

crysis 3 likes hyperthreading cpu's it has been well optimized so will give good performance with the minimum of threading overheads.

next year we may see a step change in gaming where hyperthreaded cpu's will become beneficial in a way they previously werent. pretty much to the way console games will be programmed.
because the console cpu's will be running so slow (1.8ghz) they will have to use threading more effectively to get the higher workloads done so in theory the new ports will hopefully implement well optimized threading on the pc versions. as pc cpu's are genrally faster the likely hood will be we may not need an 8 core to get comparable or better performance. we should still be able to use a 4 core and still get more grunt than the consoles offer.

Thanks for the answers guys, anyone else have anything to add?

let buy i7, i want to add that, xDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD
