Threads and cores becomes confusing, there is no reason to talk about threads at all really. All that matters is how many cores a game can use.

If a game only supports 2 cores it will only use 2 cores. Windows will attempt to even out the load showing usage on all 4 cores, however max total usage for that game will be seen at 50% max total core usage on a x4, less on a x6, more on a x3, 100% on a x2.

Likewise, windows doesn't view HT as 4 cores 8 threads, it only sees 8 cores. If you have an x4 with HT and the game uses only 2 cores you will only see 25% max cpu usage. If a game supports 4 cores, on that same chip you'll see a max usage of 50%.

A core 2 duo will perform nearly the same as a core 2 quad in a game that supports only 2 cores. If the game supports 4 cores then the core 2 quad will be much faster than a core 2 duo. Having extra cores than a game can use only helps in providing additional power to run other system tasks while gaming, its a small difference.


Edit: When he says they don't use four cores because it's using 2 cores 4 threads @ 40% usage he's wrong. It's using 4 cores, 40% usage denotes that he's approaching a point where his cpu will begin to bottleneck the gpus in that game.
Thank you, that's what I was going for.
The first part was interesting though, didn't know.
