    Hi,

    I'm buying a new computer with Vista home premium (32 bit), and I can't decide whether I should get a 2.4 quad core or a faster dual core (since it's cheaper).

    I've searched about this but all the results I've got were from 2007, so I'm not sure if things changed much now.

    So what do you think? will I benefit from the additional cores? or shall I go with faster dual cores?


    appreciate your help :)

    Of course the 2.4 Quad, you get 2.4's, more like 2.3's cause they get a bit slower the more you have, so 4 x 2.3 or 2 x 2.8? Of course the quad core.

    The speed of calculation isn't too important, 2.3 is more than enough even for heavy applications. The main thing you need is multiple cores to handle multiple programs for multitasking and handling applications that use multiple threads as they run. Also your CPU usage will be much lower on a quad. Allowing you to run tons of programs at the same time.

    1GHz is 1 Billion Calculations per second, so 4 x 2.4, 9.6 Billion Calculations per second is alot more than 2 x 2.8, which is 5.6 Billion Calculations per second.

    And Also, A big role in processor speed is the Cache, so get the largest you can, if it cache all the info it's processing, it's limited, so get the largest cache you can for the price.

    Thanks Classified95 :)

    The thing is I read in a plenty of site's online that the advantages of quad core only shows in the few applications that actually utilize this kind of power.

    So, are you saying that the operating system (Vista here) will split the load between cores so things work faster whether the applications use multiple threads or not?

    Well, I'm not too sure about quad cores, I've used dual cores of 3 different computers and I notice multitasking is much easier, and I can do a lot more of it cause it's like 2 single cores in 1. If you look in task manager when your doing a lot, on the task manager performance tab you can see all your CPU's. For me it shows both seperated, and they're both about equal when under a lot of load, they're both at about 40 to 50%, when one spikes up the other spikes up too most of the time. I'm assuming the same thing happens with quad cores. Most programs now are multi threaded so they can be used by all the cores. Whatever you do it's up to you, but I'd get the quad. Much more multitasking capibility.

    Look at these pictures for example:
