Dual Core question ????????? HELP

post #1 of 14
Thread Starter 
Hey guys quick question i have the 570 p4 775 (3.8 1mb L2 cache) i was wondering i was goin to buy the new p4 dual core cpu it was running at 2.88
2mb ls cache do uguys think i would see a performance increase or a decrease if i was to purchase it i game a lot so it kinda important i spent a ton on my rig and i pretty much have it maxed out and im looking for anything that will get me a little faster thank a ton fellas

Right now, you may not see any performance increases until games begin to utilize both cores. The only problem with dual-cores right now is that they are very warm, and adequate cooling is required.

i have a liquid cooloing systems that i just got not to long ago so cooling isnt a question but i figured since they are dual cores they would be running hot but do you think that it will out perform my cpu now ???

I wouldn't pay extra money for a dual core right now.
Almost no game makes use of dual core today.
If you want to get additional performance then get a Pentium 4 6xx series along with a good overclocking mobo (Abit, Asus, MSI, etc...) and DDR2 Ram rated 500MHz at least so you would still have headroom to increase the FSB.

**Edit: From what I notice, you're already running a well overclocked system.

The only good thing dual core CPU's are good for is multitasking and DVD encoding and decoding. You will not see a performance increase unless you run two games at once, and set the first game to CPU affinity 1, and the second game to CPU affinity 0 (in the Windows task Mgr.). But your current CPU will outperform the dual core runing at 2.9GHz in every current program/game.

There is very little point in using a dual core system at this moment in time. The reason behind this is because very few applications are able to make use of a second core becuase they are not written for multithreaded or dual core CPU's. If the code can not make use of it then there is little point of having it as it will sit there doing nothing. As mentioned before the only reasons would be if you intend to play a game while encoding/decoding a DVD or something like that as then you will see a huge boost. This is because you can set one of the CPU's to do the encoding/decoding and use the other one to run the game, thus they both work at good speeds. For gaming currently you will notice a decrease in frames if you switch as there are no games that can fully use two processors. Also the dual core CPU has a lower clock speed this will also help to reduce frame rates.

In the future you will be able to use them, like in Unreal Tournament 2007
As for their overclocking ability it can be good or bad depending on the system configuration. If you have good components and decent cooling then I would expect a fair overclock, but not as high as a single core system due to their huge thermal output.

However on a side note NVIDIA's new drivers are able to work better with multiple CPU's, namely two. So NVIDIA fans will notice a boost whereas ATI's new drivers still have no enhanced support for multiple CPU's that I am aware of

Dear all,

Reading your posts,e very day I learn a few with yours. I didn´t know that you can aim every task to every core...do you know how I can do this?

Many very thanks in anticipating

mobutu16,
You just do like Some_idiot2 said in his post above.
You press Ctrl-Alt-Del to make the "Task Manager" window appear.
Then you go to the 2nd tab which says "Processes" and you right click on the process and you set it to use CPU affinity 0 or CPU affinity 1.

You will not see an increase in your gaming mainly because of the difference in the different speeds of the two processors. That being said if the two processors were rated at the same speed you should see an increase in preformance because one core could take over operating system duty while the other runs the game. That being said the whole notion that 1 core would go to waste is somewhat misleading. I fold so both of my cores are being used at all times, but even if I did not fold I could be running a encoding application or something else while I game and experiance no preformance loss.
