Why not?

It would mean the game is very threaded with a lot of related data across threads.

HT might fit into certain specialist tasks, or can be used as a "speed up" of sorts in certain cases. But for gaming, I can see gaming migrating towards better utilization of multiple cores - since all makers are using multiple core processors on all but machines not intended for gaming. Multiple cores will always be superior to anything HT can pretend to bring forth.

For the right now - GPU is generally far more important for gaming. Most games do not utilize multiple cores or multile threads, but certainly do use the GPU very heavily, and extras, like PhysX or whatever, may reap further benefits with certain games that use those features - but your mileage may and will vary with those features that are too proprietary or not widely supported.
What do you mean? If a game shows CPU usage of more then 4 cores, and the CPU has HT, the additional threads from HT will work. If Battlefield 3 can use 8 threads, an i7 will out perform an i5 by a good margin if HT is enabled.

I've never run in to a situation where a game that can use more then 2 threads, did utilize the HT on my i3 and give a performance boost. Games that use only 2 threads perform like they would if I had HT disabled.

I believe Windows handles how the threads are utilized. Though a developer could decide if you should have a specific core tied to a specific function(1 just for physics, or something).

I don't really see why they would make games to take advantage of it, since it already happens if necessary..

I wouldn't say "a good margin", it should have some benefit. However if we look at i7 vs i5 scores in 3d mark 11 we can see at least in that test there isn't really much of a difference.

http://3dmark.com/3dm11/1219637


i7-2600k @ 5039MHz

GTX 470 SLI @ 905 core

3DMark ScoreP 11776
Graphics Score 12175
Physics Score 11663
Combined Score 9568
GraphicsTest1 52 FPS
GraphicsTest2 55 FPS
GraphicsTest3 79 FPS
GraphicsTest4 38 FPS
PhysicsTest 37 FPS
CombinedTest44 FPS

If you look at my score with similar clocks with the same cards only an i5-2500k I get this:

http://3dmark.com/3dm11/1306217


3DMark Score P11512
Graphics Score 12055
Physics Score 10414
Combined Score 9762
GraphicsTest1 52 FPS
GraphicsTest2 55 FPS
GraphicsTest3 78 FPS
GraphicsTest4 38 FPS
PhysicsTest 33 FPS
CombinedTest 45 FPS


While in the Physics test the i7-2600k is clearly faster... When push comes to shove, enough though our scores are almost identical in test 1-4 with him being 1 fps faster in test 3.. He's still 1 fps slower in the combined.

Can the i7 be faster than the i5-2500k in gaming? Sure. It will however not be a great difference. The thing to remember is that code needs to be optimized to utilize HT well, otherwise we see things like this where the i5-2500k is faster when it matters. This is true in a lot of games that don't use more than 4 cores, games that use 2 cores seem to perform slightly better on an i5-2500k than they do on the i7-2600k.

With HT off, I cant see how a 2500K can be faster than a 2600K, But anyway with 4.5Ghz it may last us for 3-4yrs in gaming as games usually pummel the GPU more.

With HT off it's an i5-2500k with 2mb more L3 cache.

I disable HT for daily use to lower vcore and temperature. and i enable it for rendering/gaming etc.

Why would you enable it for gaming? In what games do you actually see higher frames with HT on as opposed to off? I honestly can't imagine any.
