Ok over asked question but I cant find the answer..

At the moment i know hyper-threading isnt used all that much in gaming however in 1+ years time will this change? Is it worth me purchasing an i7 over an i5? In previous builds ive gone for i5s and never needed hyper-threading however in previous builds i never expected games to use 8GB Ram but these days they do...

GPU will be a gtx 970. CPU between i5 and i7 (forgot the current models) - the most popular ones probably.

I wont be going down the DDR4 route

There is a common misconception that more cores always is better. As for gaming today, more than four cores isn’t better. It’s often worse. And that’s because most games won’t make use of the additional cores. Intel’s highest-clocked chips are quad-core, not six- and eight-core. In reality, the difference isn’t enough to actually feel in games. Four cores is usually plenty for gaming.

There are a few titles like BF4 that are designed to use more than 4 cores, however BF4 is bottlenecked by GPU not by the amounts of cores and there are no reports that even on a Titan X card, that more cores will mean meaningful performance increase. However running multiple graphics cards in SLI/CrossFire or Titan Z, may benefit from more than 4 cores...

As long as you have a quadcore CPU, it won´t help. Games usually use max 4 cores, and hyperthreading is thus superflous.

Should you run into a game that uses more cores than your cpu has, then hyperthreading may help.

Alot of games already make use of hyperthreading but it's not like you get 100% more performance, because of twice as much logical cores. The difference is pretty small i don't know how big it is but usually not worth the extra money. However if you got some money to spend without any problems and want the best performance then it's always the i7. If not just go i5 they are very strong for gaming only. As long your CPU doesn't bottleneck your GPU you're fine anyway. Anything above that is just like 1-5 extra fps from the faster CPU.

My guess is that it will take quite some years to really see a big difference in gaming between hyperthreading and non-hyperthreading CPUs.

Hyperthreading isn't useful as of right now, because as others said, most games don't take advantage of it. However, DX12 will make hyperthreading more useful, but I doubt you will see a large performance decrease.

That´s why Sandy Bridge is going so strong, even today.

Four cores are enough for a foreseeable future, Benchmarks of DX12’s new multi-threading show no benefit beyond four cores, sometimes it even performs worse. Surprise surprise.
