I was thinking about going with a 790i ultra, but after reading more comments about it, I'm gonna be getting a 780i. I've read that the memory standard is ddr2 800, but supports up to 1200 with epp. Would that mean that, assuming the ram has epp, I'll be okay with a set of DDR21066?

If it makes a difference I'm looking at the XFX 780i and the Corsair Dominator DDR1066.
 
Which CPU are you going with? Q9300? Q9450? or Q6600? Anything with a high multiplier (Q6600 has a 9x multi) won't need anything faster than DDR2-800, simply because the intel platform doesn't really take advantage of such high RAM speeds alone. It performs best in a 1:1 ratio. If you're going for a Q9300, what are your OC'ing goals?
 
I was looking at the e8400 because of the ease of oc'ing with it, but I'm still open to changes. I'm not going to be doing huge overclocking, maybe just something like .6 increase. I've never oc'd with anything but a single core, is it roughly the same for a dual/quad core? Also, What exactly do you mean by 1:1 ratio.

As for the mobo, is there really an advantage to going with the P7N? I'm not to fond of the colors of the board. Sorry if that's what the link was for, it's not loading for me at the moment.

Sorry for the noob questions. Last time I did a build was back when dual core was pretty new so I'm a bit behind with this new stuff.

Formulas for Intel platform @ 1:1 settings: (base FSB speed is SDR, or single data rate)
c × [Base FSB speed] = CPU Clock speed (c = CPU Multiplier)
2 × [Base FSB speed] = RAM speed (DDR: double data rate)
4 × [Base FSB speed] = Effective FSB speed (QDR: quad data rate)

On Intel platforms, running the RAM higher than a 1:1 ratio with the CPU is, for the most part, useless, so don't bother trying to do so. If the BIOS/EPP does it for you, just let it. All you need is a 1:1 config, though. Here's some possible clock speeds (as always with OC'ing, your results will vary):

E8400: 9 × 333 = 3.0Ghz, DDR2-667 << STOCK
E8400: 9 × 400 = 3.6Ghz, DDR2-800 << Nice OC
E8400: 9 × 445 = 4.0Ghz, DDR2-890 << Good OC
E8400: 9 × 500 = 4.5Ghz, DDR2-1000 << Great OC
E8400: 9 × 533 = 4.8Ghz, DDR2-1066 << Nearly Impossible?

Haha, I laughed when I read this. I don't blame you on the colors. I really don't like the fact that the memory slots are orange and green. It makes the board look more of a toy.

I see I see. Just to be sure with what you mean by this
E8400: 9 × 333 = 3.0Ghz, DDR2-667 << STOCK
E8400: 9 × 400 = 3.6Ghz, DDR2-800 << Nice OC
I would oc my cpu to match the ram speed, correct? Meaning no oc'ing the ram?
 
Alright then, looks like you guys have saved me a bit of money. Thank you very much :D
 
FYI, those E8400 chips can reach 4Ghz and higher, with good air cooling. ;)
