Hyperthreading - A quick/basic question

I was going to upgrade my current mobo and processor from a p3 1.0 to get a p4 3.0, and being the Hardware newbie that I am, know the following things about hyperthreading:

1) It exists.

So....do all p4 3.0's come with hyperthreading, or is it something extra you have to ask for? If so, is it at all useful for someone who's just gonna use it for normal computing and gaming?

Sorry for such a silly simple question, but I'm a software guy, and know very little about the other side of the computing spectrum..

Thanks for all your help guys! :)

(By the way, I'm also getting 512 of DDR ram and a new case/power supply. I have a radeon 9500 video card and an SB live sound card, and plenty of HD space, so thats all i'm upgrading.)
 
Sorry, in my ignorance, i didn't realize that hyperthreading is an intel only thing :D. I'll post in the proper forum next time.
 
Yes, all Pentium 4 3.0GHz processors come with HyperThreading. There were 2 versions of the 3.06GHz Pentium 4 (one with HT, one without).

Also, if you're getting 512MB of RAM, make sure you're getting two (at least) PC3200 256MB modules and a motherboard that supports dual-channel DDR (i.e. based on the 865PE or 875P chipset)

Yes. That includes the 3.0C and 3.0E models. You'll need to ensure that HyperThreading is enabled in the BIOS, and that you are running Windows XP Home or Professional Edition. Your chipset must also support HyperThreading, though this is pretty much guaranteed in any motherboard you'll encounter.

It's useful if you're a big multitasker. If you one two or more processor-intensive applications simultaneously, HyperThreading is going to help the performance of all applications where they would otherwise chug. Since you're a software guy, perhaps you're familiar with multithreaded applications? HyperThreading can also improve performance in these programs, though not nearly to the degree of a true multi-processor setup. Games don't benefit from HyperThreading at all; in fact, you may lose a frame or two per second. However, if you're playing a game while another processor-heavy application is running, you will be seeing smoother framerates with HT enabled than if it were disabled.
 
Thanks for the info guys, its very much appreciated. Yea, I am getting a pair of 256 meg chips. At first I questioned why they would send me 2 256mb instead of 1 512mb, but now I understand. Thanks a ton! :)

its so you can do a dual channel setup, you cant do dual channel with just one stick, dual channel improves something :confused: i am really new to that dual channe thing ><
and they send you the 2 together to ensure that you can actually run them in dual channel, theres some info in the memory forum , theres a thread thats got a lot of info in memory matters
