Alright, I'm building a new system. I know everything I want except the memory.

Now, is it better for me to buy DDR2 800 with 4-4-4-12 timings

or DDR2 1066 with 5-5-5-12 timings?

If i'm not going to overclock and my board is rated for DDR2 800 memory, does that make any difference?

Alright, so you're going to get an Extreme processor.
And you're not going to overclock... :?:
Well, do whatever you want, your parts, right? :)

If you're not overclocking, you just need RAM that runs at the supported FSB of the processor. Core 2 Duos use FSB 1066Mhz, which translates into DDR2-533Mhz. So that's the minimum you need.

However, buying anything higher than 533Mhz allows you to overclock. You can buy RAM that is DDR2-800Mhz and run it at 533Mhz speeds.
If you plan on overclocking later, get the high speed RAM.
If you never want to overclock, get the cheapest RAM that is at least 533Mhz.

For the 5-5-5-12 1066Mhz RAM, it can probably run DDR2-800Mhz at 4-4-4 as well, but you might want to double check on that. It depends on how much you want to spend, etc.

I have heard bad things about Corsairs quality control. Ive bought from Kingston twice though and with no problems. I plan on buying this 2gb kit:
http://www.newegg.com/Product/Product.asp?item=N82E16820134046&Local=y

It isnt fancy or very overclockable, but it does have a lifetime warranty.

If you want a good deal on overclockable RAM try this one:http://www.newegg.com/Product/Product.asp?Item=N82E16820609026
Super talent with fancy timings.

Have fun with your PC and be sure to update windows and install protection programs before connecting to the internet at all.

Seeing as you have the $$$, you have many choices:
Overclocking: As someone else said, get the highest mhz ram that you can.
Non-Overclocking: Get the lowest cas latency you can, with a frequency from DDR2-667 on.

BTW, what PSU have you picked? My motto, especially for such a highend beast as yours:
"DON'T SKIMP ON THE PSU"
Secondly, if you want to overclock this thing like there's no tommorow, let's talk cooling (Feel free to PM me. I'll be glad to help). 8)

Keep the ddr2 800 memory as its tighter timings will give slightly better performance at stock speed.However the 1066 mem.will give you a lot more headroom for oc'ing.

Yeah, I've heard good things. They don't carry it at my local shop. I hope Newegg has in stock, otherwise, I won't know where to pick it up.
