Which processor should i go for?

Specs: Windows XP
Hello members, this is my first post here. I am a new member and i am from India. So please neglect any errors i make in the language.

I just bought a new mobo namely MSI G41M-P26. Also i have the 2 GBs of DDR3 RAM (single module).
Now i want to buy a processor for this mobo, i've sorted out from core-2-duo and core-2-quad processors. I've chosen C2D E8400 & C2Q Q8300, Q8400.

Now my Big Q, about which i am confused is that which one is better in computing-power, C2D or C2Q? And which one shall i get out of the above mentioned CPUs and why? I will also upgrade my RAM to an additional 4 GBs.

And one more thing, you might think that why i bought this obsolete technology's mobo then i will say that that's the another painful story!! And, also, these are the only C2D and C2Q processors available still in indian market, so please suggest me out of the above.

One more thing, FSB for mobo is 800/1033/1333 and RAM is also having 1333 MHz frequency.

So friends, it will be of great help for me if you wise people suggest me wisely. All your help will be greatly appreciated.

I'm curious why you went with an old LGA775 setup rather than going with the a Core-i3/5/7 CPU & board? Here's your motherboard specs:


I'm also curious why you bought 2GB RAM? The board you chose only has 2 memory slots so to be able to run dual channel mode, you will have to add another matching 2GB stick. What you should have done was buy an 8GB (2 x 4GB) dual channel kit.

"One more thing, FSB for mobo is 800/1033/1333 and RAM is also having 1333 MHz frequency"

None of those are frequencies, they are QDR & DDR speeds. 1333MHz FSB CPUs run at 333MHz frequency. DDR3-1333 RAM runs at 667MHz frequency. Whether you get a dual-core or quad-core CPU is up to you. It depends on what your primary use will be & how much you're willing to spend. You certainly don't need a quad if all you're going to do is surf the internet & send emails. And if you plan on playing games, you'll need to add a PCI-e video card because the integrated GMA X4500 isn't going to cut it. Here's the CPU support list:


Whatever you do, make sure you invest in a decent brand name power supply (Antec, Corsair, Seasonic, etc), not a crappy VIP, iBall, or no-name generic unit. Do you plan on overclocking or will you just be running everything at it's default settings?

Thanks riider for your concern towards my problem.

As you said that 1333 is not the frequency for DDR3 RAM, so, let it be. But just tell me whether the 3 CPUs which are available here will get in correct configuration with existing RAM and mobo? You know, i am not a computer or hardware expert to have such deep and vast knowledge about all these. And as long as the RAM is concerned , as i said earlier, i am gonna upgrade it 2 Dual-Channel 8 GBs. So, please suggest me about that also and also tell me, if, possibly not, i dont change or upgrade RAM, then will it cause any prob?? Is the current RAM's rating is below the mobo and the CPUs i shortlisted?

Once again thanks for the help, looking forward again for the expert views, opinions and suggestions.

I asked a few questions that you didn't answer. What are you going to use this system for? If it's only for email & the internet, you'd be wasting your money on a quad-core CPU, in fact, you could probably get by with a cheap Pentium Dual-Core. However, if you plan on gaming, you probably should get a quad.

Do you plan on overclocking or not? If you do, you can get a cheaper CPU & simply reconfigure the settings to run it at the same speed as a more expensive CPU.

Dual channel mode is a function of the motherboard, not the RAM. But to enable
dual channel, you need a matched pair of RAM sticks.

"as i said earlier, i am gonna upgrade it 2 Dual-Channel 8 GBs"

No, you mentioned a 2GB stick then adding 4GB later. That will give you 6GB but it will run in single channel mode, not dual channel, which means you'll lose 50% of the potential memory bandwidth. And you can't run two 8GB sticks because your board only supports a max of 4GB per slot (8GB max).

All of those CPU's are 1333FSB so there will be no OC'ing on that board which is fine if you do not plan on overclocking. If you do plan on overclocking then choose a 1066FSB CPU like the E7xxx or Q6xxx for less money and when you bring it back up to 1333FSB you will be running at a significantly higher speed. (an E7500 could in theory run at up to 3.66GHz at 1333FSB (Freq.333MHz) which is significantly better than the E8400's 3.0GHz).

As riider said, dual or quad depends on your usage and your funding. Getting a more expensive quad but 'cheaping out' on the power supply and the graphics card in order to be able to afford it does not make a good machine. Getting a fast dual core with a better power supply and a better graphics card does make a good machine. The system needs to be balanced and your selections need to be targeted to your needs today and in the future.

Note, selling the board for what ever you can get for it and going with an Intel i3 or i5 and suitable board would be even smarter if you can swing it. A socket 1155 board with a second generation i-series CPU being optimal and preferable.

You have to be a little bit crazy to keep you from going insane.
