I7 HT and turbo for gaming

Not at all.

I think bad company 2 would use more than 4 threads and be faster with HT on, however the difference will not be noticeable.

If I had an i7 I would overclock it, turn off turbo but keep HT on.

If you disable HT then you may as well have spent your money on an i5 750:p.
 
Hyperthreading - not really. Current games do seem to use all four cores physical cores, but from what I have seen - the extra virtual cores provided by hyperthreading don't make any difference in current games. However, hopefully future games will be written to make full use of hyperthreading as it is becoming much more common on intel chips - with the new i3 and i5 CPUs replacing the older Core 2s.

Turbo - yes. If a game isn't using all cores then this can speed things up. However, if you are overclocking I would suggest turning Turbo off - so you know exactly what speed you are hitting.

My suggestion if you are getting an i7 is to get a big cooler for it (Titan Fenrir, Megahalems etc.) keep HT on, turn turbo off and overclock it to at least 3.6GHz. Its really easy to do and will give you excellent performance.

thanks for the help guys I gonna shot for 4-4.2ghz on it I have a good cooler so I presume HT should be of for that too to use less volts.

I would go for 4ghz with HT on and turbo off.
You could probably do 4.2ghz but it depends whether you are happy using voltages that Intel say will degrade your chip over time.

My i5 will do 4.2ghz but I personally don't think that the extra 200mhz is worth it.

What voltage would that be?

Cannot remember off the top of my head sorry.

With overclocking there is a region where no voltage increases are required. Then above that there is a region where a small voltage increase is required.
Then beyond that is a region where a large voltage increase is required just for a small speed increase such as 100-200mhz.
 
I'd go with turbo on, but only for the higher multiplier. If you enable it in your bios, it'll force turbo on permanently (confuses a few programs, but works nicely). Definitely leave HT enabled, or like mglover070588 said, you just bought a very expensive i5 750.

What are you running? You don't really need to go over 3.5ghz with an i7, other than for bragging rights.
 
From what I understand there is no real benefit from disabling HT, it won't get you higher clocks.

As for turbo if you aren't overclocking then definitely keep it on as it will help for single threaded games. If you are overclocking, then as mentioned you may as well just set a fast clock all the time (speedstep excluded, obviously).
 
as far as i know disabling HT does lower temperatures but IMHO its not worth the potential performance loss u will suffer in certain applications and/or over-all system performance.
