Which motherboard for my needs?

Greetings, I've decided to scrap the entire previous idea of mine to go with a CF setup.

I need advice on the whole SLI option...First off how does Dual PCI-Express work? 2 identical SLI or CF cards? where as an SLI needs one SLI card? Please clear this up for me..

Now, I don't plan on purchasing a second GPU for atleast 1-2 years. That being said, should I even bother with a SLI - or dual PCI Express board? I want my PC to last me upwards to 4 years before building a new one.

I will most likely buy one of the following, BFG 8800 640mb or the 768mb GPU.

My main problem is with the MOBO for the Intel Core Duo 6400 I will get.

I've read numerous reviews, and can't make up my mind.

Here is what I need from my MOBO, Firewire, good features, good overclocking potential. I don't plan on doing maximal overclocking as I am new to it, but I would like to do some, maybe 70% of its full OC potential.

If you recommend I toss the SLI idea out then a single PCI Express card is fine.

Here are mobo's I've looked at in depth.

1) ASUS P5N32-SLI Deluxe, reported to have strange overclocking results, otherwise has all features I am looking for. $240

2) ASUS P5B-Deluxe WiFi, still need to do more reading on this, but has all features I want, Dual PCI Express--> as stated above, I need clarification on this feature. $230

3) ASUS P5B-E, Amazing on overclocking, but only 1 PCI express slot...again if you feel I should steer away from dual GPU support, this might very well be my choice. $180

4) ASUS P5N-E SLI, excellent overclocker, not as many bells and whistles on this board. $160

5) Gigabyte GA-965G-DS3, good choice but no firewire or dual PCI Express. But I know this board is really good.

So please help me, I've been trying to build this system for almost a half a year, it is getting rather frustrating. Feel free to recommend other boards I have not mentioned.

As far as the rest of my system,

GPU- BFG 8800 640mb or 768mb, probably the cheaper one.
Intel Core Duo 6400
Corsair 6400c4 2gb ram 800mhz or maybe G-skill or Team, but Corsair is tested on most of these boards, hence why it is my choice.
I already own a OCZ 700W GXS PSU (bought yesterday got a good deal)
and I am leaning towards a Lian-Li PC-A16B, although I am not sure yet...feel free to recommend a Case for me as well.

thanks very much for all your help in this thread and my previous ones.

I like the P5B-Deluxe. Both SLI and Crossfire are a waste of money. That 8800 is going to be oodles of gpu power. If you do want SLI then you need an i680 mb. If you want crossfire, go with the P5W-DH. If you decide to run a single video card, you just cant beat the P5B-D.

hi, I am assuming you are referring to the WiFi version of the P5B-Deluxe?

There is another P5B- Deluxe. Anyway, thanks, I will hopefully get more responses

As far as I know, the only difference between P5B-D and P5B-D WiFi is the WiFi. Someone can correct me if I am mistaken.

you said CF & SLI is a waste of money......so why do you like the Deluxe over the E version of the P5B? The deluxe is CF ready according to what I read on ASUS....thanks again.....the P5B-E also overclocks better...

I have 4 monitors, thus I still need two video cards.

Oh and please be careful with the ASUS P5B Deluxe it does have 2 PCI-Express Slots one running at 16x but the other ONE ONLY running at 4x or 2x what ever you choose

If your only thinking of running one card, 8800 GT would be a very nice choice/combo with the ASUS P5B - Deluxe, plus it has great overclocking capabilities.

And Intel is not AMD which places this thread is a rather amusing context.
