Hi, I was looking to buy a new computer. I wanted a quad core because of the speed, but i heard that daul core is faster with most of todays games and apps. I heard that Daul core uses "threading" which means that the 2 cores work together to give you the speed. So a daul core of 2.4 ghz is actually 4.8 ghz. Ok.. But quad core dont work like that is what i heard. Quad core uses the core seprately. So if you have a 2.4 ghz quad core, the most you will get out of it is 2.4 unless you "over clock" but even then you would only get about 3 ghz. I also heard that nearly all of todays games and apps dont even use the quad core technology. They just lay there and go to waste. I assume what i have said is basicly true, but i am not 100 percent sure. I would like to get a couple years out of my new pc and be able to handle newer games for some time. I got 5 years out of my P4 2.8 ghz. So, that all being said, which is better daul or quad?

i have a intel quad core processor i have windows xp running on it . i want to know is it possible to install mac using any virtualization software. if so how

Hi.
I want to do some virtualization using either Sun’s Virtualbox or Vmware. I will use Ubuntu as host operating system and I want to run about 8 installs of XP concurrently as guests. All of these XP guests will simultaneously do stuff on the web.

I need to buy a monster machine to handle this. My money can either buy me an i7 cpu with a little DDR3 ram (4-8gb) or a Quad Core (q9400) with about 16 gb of DDR2 ram.

It seems like the cpu is powerful enough in both cases, but I believe the extra 8gb or ram will come in real handy when it comes to virtualization. I believe the bottlenecks in virtualization would be located elsewhere, such as I/O. Please tell me what you feel would be my best choice.
4 answers in about 10 minutes… wow ! Are you guys on standby waiting for these questions ? Anyways, thanks for the good answers so far. I will wait a while until I award the winner to see if some more geeks respond. Please keep ‘em coming people.
I respect the opinion that the i7 is the fastest cpu and is good with virtualization, but I think i will go with quad core, cause I believe I need as much extra ram as my budget will buy. Honorary prices to all that suggested that Quad Core is the way to go, Quad Core is what I will choose. I will vote for user "Divot" as the winner though, because of his valued opinions about cache and DDR3. Thank you all that responded.

Intel Quad vs AMD Phenom x4 for Virtualization , I will use software like Vmware and virtual pc, and will not heat up also
