Processor

It depends on what you are looking for and what platform you want to build on.
Here is a good chip: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If you give a little more detail I can guide you better.

motherboard supports intel processors

What socket is it and what do you have in it?
Is it a store bought pc or home built?
If it is store bought what is the model?

Which motherboard model are you using?

There are many intel processors that run on many different motherboards.

socket 775
mb gigabyte ga 945gzm-s2

You could get either of these:

But what do you have in it right now? If you have something close to this it may show little to no difference.

8600gt
1gb 667 + 2gb 667

i dont have

Which processor do you currently have in your motherboard..??

Is this a new build? And have you already bought the mb?

I mean what chip do you have in it right now. I’m guessing that you are just upgrading an older pc.

builded

I’m sorry I don’t know what you mean.

I think he means its already built he just wants to get a processor for it.

I would say your best bet is to go on ebay and look for either an E8400 or a Q8200 both will work and should be able to find one around $100 on eBay.

I guess; I hate telling people to look on ebay, but it is his best option.

Yea meto but for older parts you can find some good deals.
