Memories!

Sorry, this memory thing is just confusing..
What I do understand is this (hope I got it right)
There's almost no difference between DDR2 and DDR3- There's not much difference between 800mhz and 1066mhz, the power saving is negligable, and at this time both memories preform the same. I've also heared that in the future DDR3 will become better.
I need to know this:
1) Does the future preformance of DDR3 depend solely on the increase in speed (1600mhz preforms better than 800, while 1066 vs 800 is negligable), or does it have something to do with the DDR3 itself (meaning that in two years will there still be no difference between DDR2 at 800, and DDR3 at 1066?)?
2) I know you can't put DDR3 in a DDR2 slot, but can you put DDR2 in a DDR3 slot? Meaning, if I get a laptop with a montevina, capable of DDR3, but put DDR2 in it, can I upgrade it to DDR3 later when higher speeds come out?
3) Is it even worth upgrading? Does the FSB of the processor have effect on the memory speed? The ones coming out today have only 1066, so when higher clocked memories come out, such as DDR3 at 1600mhz (Or whatever), will they work well with 1066 FSB?
4) And while we're on the subject, what is exectly the big deal about the 1066 FSB? How much better is the montevina than santa rosa? Why should I want to get it? I know it also consumes less power, how importent is that?

Thanks in advance, and sorry about all these, it's just so obscure and vague, I'm not sure it's worth the extra $$$..
This comes after reading the "how it works" articals, that I think should be stickied here, since they are very relevent to laptop buyers. And are also awesome

 

1. I'm moving this to the hardware forum.

2. We were discussing DDR2/DDR3 a few days ago. See this thread.

I won't be making DDR3 RAM a key requirement for my next notebook.

Unless they release DDR3-L for notebooks

 

1. No but it does play the biggest part
2. No
3. Up to you, IMHO No, and no i dont think DDR3 1600 will work in DDR3 1066
4. Higher bandwidth = more data faster. Not much. Who says you should want to? That depends on you; how much battery life do you need?

At the moment, no it really isnt worth it, but in about a year or so, DDR3 will become the standard.

OT - Yes flipfire i am following you

 

That sucks.. So if I get DDR3 @ 1066 now, I may never be able to upgrade it to DDR3 @ higher speeds if needs be?
Also I'm still fuzzy on this- when will DDR3 be better than DDR2 (in ways you can actually notice), and why (I'm guessing it's the higher speeds, if so at what speed should there be an actual difference)?
Oh, and thanks for the answers so far, this is very helpful.

I've read it already, that artical is what brought up all those questions in the first place and it doesn't answer them, so please, anyone..

 

DDR3 is better than DDR2 at the moment; read Powerpack's math and compound the data using higher file sizes. The thing is, at the moment, the Price for performance of DDR3 in comparison with DDR2 is not worth the money.

 

DDR3 is better than DDR2, but it's not noticeable at the moment, I'm wondering when will it be noticable, at what speeds, and how long will it take for that to happen?
Also according to you DDR3 @ 1600 wouldn't work in a computer that has 1066 FSB, so if that's true then I may never be able to use DDR3's full potential..
So are you sure about that?

 

Yea, your chipset wont support it.

 

Blah.. Thanks
