Should I build a new PC? (what is multithreading?)

I'm currently running a 3.0ghz P4 and an FX5900. I mainly use my PC for gaming and maybe some matlab.

Should I get a 7800GTX and an Athlon 4000+? Or should I hold off another year or so until the next big 3d chip and proc come out?


(And what is multithreading? Does that require 2 cores? A A THG article said multithreading will be "everywhere" in a year from now...)

Thanks!

Your still have a pretty good setup there, unless you really feel that youd need more power I wouldnt upgrade, unless money is burning your pockets =).

For games you processor shouldnt hold you back, the Fx5900 has some issues with newer directx 9 tittle, I would upgade it before your cpu.

if you have a 3.0 ghz(or a 3.06) you should have HT. Ht doesnt require two processor, its a technology used by intel to "fool" the OS. It create two virtual processor using the same ressources, it adds some perfomance when running multiple applications.

Dont beleive everything THG says! Altough Dual core(two actual procesor on the same chip) and HT enable processor will probably capture a large part of the market in the next years, its not a must have especially if you dont mutlitask all that much.

Oh and for matLab if you have a gig of ram its probly running quite fast! Altough it would be faster with a 4000+

If a CPU has multithreading it behaves as if it had two processors, one of them virtual. Right now some Intel CPUs have multithreading it's called hyperthreading, but there aren't many applications optimized for it.

Wooohooo scooped you! with a longer post I might add! And some1 second me :wink: .

Good stuff that posted tough I didnt say that Ht = intel's way to multithread..

I hate getting scooped, it happens all the time, especially when I am making linkies.

Multithreading is:
Quote:
The ability of an operating system to execute different parts of a program, called threads, simultaneously. The programmer must carefully design the program in such a way that all the threads can run at the same time without interfering with each other.


Intels 'Hyper threading' simultates a second CPU core to the OS. This sometimes increases perfomance when running multiple Apps or a multithreaded app.

Dual core is an extension of this, instead or a virtual second CPU, there is a physical one.
