hyperthreading useless in gaming?
meaning, buying a pentium is no difference from i3 if put in gaming situations?

Yea pretty much unless the game can actually take advantage of the HT feature take a look at this graph:

You can see the pentium is right near the i3 in GW2.

Totally depends on how many threads the game is designed to use.

Anything that is single threaded will see 0 difference.. 2 threads MAY see some slight improvements as you will have other processes running at the same time etc etc.
Anything that can use 2+ threads will see a difference (depending also on how cpu intensive it is)

Depends on the game and how it is designed to run. Generally speaking you are right that hyped threading does very little in games. However, I am sure there are some games designed to run 4 threads that would run better on i3 than pentium. Generally games are not optimized for more than 4 threads.

HT between the G850 and i3 can help in some games:
Intel Pentium G850, Pentium G840 and Pentium G620 Review. Page 4 - X-bit labs

When you start thinking i5 vs i7 however the difference is much less (to the point where 100MHz of overclock would be more noticeable), but with dual cores the difference is there. If I was in the market for a low-end gaming machine I'd probably go for this or wait for AMD's Piledriver CPUs to hit the desktop:

HT may help or hurt, depending on thread affinity. So, case by case bases, but generally there is a trend in compilers to increase thread affinity.

My fathers computer is a Asus P5Q with a P4 3.0 and and an 8600 GPU. passive cooled

Its Its hypertheaded more by acadent than design at the time.

It also has XP 32

Works fine fore him. He does Photos and Email and document printing mostly

What he does could all be done on laptop, and wants to Buy one

Only problem is he wants USB 3, BluRay, and a Nvidia graphics card

But he doesn't want to spend lots of money.

So my point is if you want a laptop ...

Hyperthreading increases temperatures, but does turning it off actually increase stability as well, ignoring temps as a variable for the sake of argument.

As a game ever taken advantage of hyperthreading?

There's been alot of talk lately about why Dying Light runs so differently on everyone's systems. Techland asked people to send them their game log files and a dxdiag report. When I sent mine in I noticed this line about HT: Disabled, here's the top of the log file:


{03:21:09.263} INFO: [Game] > System locale is 'En'

When I check CPU usage on Afterburner when I quit the game, one core is usually 100% while the other 3 are anywhere from 50-80%. It's an i5 3570k. Can someone explain if this is a game limitation or should hyperthreading be turned on for modern games?

HT is much more utilized in game development these days.

Do essentially a bench pick a section of the game to run through HT off then HT on.

Many game now days can benefit from more threads.
