Asus P5Q Deluxe vs Asus Rampage Formula

Hello, i'm new here, i'm from Brazil. My english is not perfect, sorry.
I would like to say, in Brazil, don't have Maximus II formula to sell yet, then i can't buy it.
I'm buying a new computer...

New Config (I already bought all)

CPU: Quad 2 Core Q9450
Mem: 4GB Corsair XMS2 DDR2 800mhz (Cas Latency 4 @ 1.8v)
VGA: Sapphire HD4850 512MB
HD: 500GB Seagate 7200.11RPM 32mb Buffer (NCQ)
DVD-R: Asus 2014L1T
Zalman 460w
_____________________________________
I wanna make a cool overclock, to make it perfect.
The Q9450 only have 8 of multiplicator, then ill need a higher FSB.
Ill make something like this: FSB 425 x 8 (Total: 3.4ghz) or, FSB 400 x 8 (Total: 3.2ghz)

[b]I dont will make a crossfire[b]
The computer is for general use, like 30% Games, 30% Multimedia, 40% internet/programs.
And ill let the computer on a lot of time, like 18/hours per day.
Then i wanna a balanced motherboard, to use daily.

At least, but not least:
The new motherboards P45 are on 65nm right? And the X38/X48 are 90nm?

EDIT:
Anyone know a review of P5Q Deluxe vs Rampage Formula?
And a review of Biostar Tpower I45?

Sugestions please?

if you won't crossfire, than i say the p5q is your best bet

sorry i don;t have any prior knowledge to a link that might compare those three boards =/

Rampage Formula

It is geared more for gaming and overclocking.
-X48 Chipset ----> 2 x PCIe 2.0 x16 , support at full x16, x16 speed
=better Crossfire performance at high resolutions

-includes SupremeFX II Audio Card

-More MOBO fan connector ports

-more "fluff" to overclock

P5Q


-Intel® P45 chipset -----> only one PCIe 2.0 x16
=a little less Crossfire performance at high resolution.

P5E Deluxe might be also good choice. It is basically a Rampage with slightly less extra stuff (less money) It is X48 Chipset based like Rampage MOBO.

From your description where you are doing NO Crossfire......Rampage might be waste of money for you.
