Dual and Quad Core Cpu's

A dual core processor has 2 physical cores, a quad core processor has 4 physical cores.

I know,whats difference in performance is dual core good for gaming?

If both the quad core and dual core are designed on the same processor architecture, and the only difference is the number of cores, than theoretically the quad core is nearly twice as powerful. The thing is most software can't use all 4 cores, so the performance difference isn't that great between a dual core and quad core for most tasks. Since you mention gaming I'll bring the discussion that way.

Easiest answer is that a high end dual core processor is still more than enough for gaming. Reason for this is until recently, most games couldn't use the extra 2 cores on the quad core processor, so there is minimal difference in a game when both dual core and quad core are at the same clock speed. The problem, is a growing number of games are being released that support more than 2 cores, and do run noticably better on a quad core. These games still run on dual core, but the max frames per second will be lower and the cpu will bottleneck the gpu in some games.

I'd personally recommend a quad if you can afford it, it'll last longer into the future for being able to run new games than the current dual cores will. But, this is only the case if you have a high end video card. If you have a low end video card, it'll bottleneck and limit your performance regardless of what cpu you have.

For gaming clock speed is still more important than the number of cores at least for most titles. Saying that assumes a dual core/ quad core debate.....single cores are pretty much obsolete.

That being said more and more titles are making use of multiple threads and making use of quads. I am happy with my dual core E8400 for right now at least but I am more of a casual gamer.

If I was building a new machine I would not have less than a quad. Windows 7 also works well with more cores. With new 6 core chips from both Intel and AMD recently released it is only a matter of time before even a quad is not enough. For now a quad is pretty future proof.

I have a Intel Core 2 Quad Q8200 Core Speed is 2.33 GHz FSB 1333.3 HHz and L2 Cache 4 MB should I change my CPU to Intel Core 2 Duo E8500 Wolfdale 3.16GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor

With the way games are going (multi-threaded) you're fine with what you have.

Are you unhappy with your current performance?

What graphics card(s) are you using?

Have you tried/thought about overclocking?

No, do not go from a quad core to a dual core. Just overclock your Q8200. It's not a great overclocker, but at least 500MHz to 2.8GHz should be doable.

A well oced Q8200 would then be superior to the E8500 (which is vastly overpriced anyways) in multi-threaded games such as FarCry2, GTA4, etc

If I knew how to overclock

Google. http://lmgtfy.com/?q=overclock+q8200

My GTA4 is lagging so hard my video card is sapphire ATI HD4350 512mb 64 bit Core 600 MHz and Memory 500 MHz thats my video card shity one  

And i dint find any overclocking features in my motherboard :|

GTA4 is a poorly optimized game for the PC...actually its optimization is pure crap.

You need a quad core CPU and a GTS250 or better just to get the damn thing running at a decent performance level. I'm shocked its not a complete slide show on your ATI 4350.

LIke I said my motherboard doesn't have any overclocking features in BIOS

  Are u thnik im a idiot who doesn't know how to overclock this cpu !

IDK but my pc from Acer (GATEWAY) thats why i dont have anything in my bios

Well, you said "If I knew how to overclock" which sounds like you saying "I'd overclock if I knew how to overclock." You made no mention
of your computer being a Gateway and lacking overclocking functions earlier.

You can either buy a new mobo, ATX case, and a few other parts so you can OC or a used 775 CPU. If you live next to a microcenter, they have Q8300s for $120, Q9400s for $140, and Q9550s for $180.

Or do another AMD build and sell your current system...

Why i bought acer :| its a shity like a DELL

Guys can u help me build a gaming pc $1400 from www.newegg.ca?

AMD or Intel?

AmD with DDR3 memory support, 1 or 2 pci-e and with good overclocking fetures

your choice bluescreen i kinda doesnt like amd ,motherboards are ***,but if u will find good one tell me

Wait can i overclock with software not bios?

http://www.newegg.ca/Product/Product.aspx?Item=N82E1681... my choice mmmmm  

Aye no problem.  

For the mobo, the ones hipped recently are PIIx6 compatible, but I read there are a few of them out there which still needs BIOS updates or it won't support x6's out of the box.

Others to consider:

Nice case. It has excellent cooling

Btw, if you want to reuse some of your components, you can reuse your DVD drive and hard drive. You can reuse your PSU, but I suggest getting the new one I listed above since prebuilt PCs usually have weak PSUs.

You can reuse your DDR2 if you pick out an AM3 motherboard that supports DDR2, which will save you another hundred dollars or so.

Of course, you can also just sell your DDR2 and other parts on ebay, etc

I calculated how much power i need.It was 360 watts but Acer put 300 watt

are you sure it's supporting x6 amd cpu?

I picked this one http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

It should be compatible.

But there are a few with non-updated BIOS out there...

I knew I need to update my bios so I decided go withAMD Phenom II X4 955 or just upgrade my old pc.
