I just built an SLI rig with the following:
Asus P5N-D (750i)
Q9450
2 x BFG 8800GT OC2s (675mHz)

I'm probably just obsessing over this, but I want someone to tell me that I am obsessing or maybe that I should change this up.

I was going to go with an EVGA NF78-A1 SLI board (780i), but the store that did the install steered me away from this board towards the P5N-D, but I didn't have time to research the P5N-D.

I have not had any issues as of yet, but have now read and been advised by other people that this P5N-D is a lousy board.

I'm considering swapping it out with something better (I don't want to upgrade for a while, although not ready for DDR3 yet).
I did my math and it would only cost me about $100 more than I have already spent to sell the P5N-D, two 8800GTs and buy a P5E and 4870.

With the new ATIs coming out, I'm just considering not going SLI at all and just getting a ATI 4870 when it comes out in a single GPU configuration for better stability.

Again, I've really put a lot of money into this build and just want the best system I can afford, and the whole P5N-D "post-buy research" I'm doing is really leaving a foul taste in my mouth.

It should also be mentioned that I do want to game at 1900x1200 at 24".

What do you recommend I do? Be happy with what I have or swap just the board out or swap out the GPUs as well.

Personally I would get rid of the P5N-D, and stay away from any SLI config, the recent nVidia chipset motherboards have a number of issues, notably when you are doing any overclocking you are likely to encounter data corruption problems.
The P5E is a much better choice if you want to stick with Asus, specially for its 2X PCI-E 2.0 x16 slots. The new 4870 would work nicely, or a pair of 4850s in Crossfire would also play nice.

Well if its running and it works, you should be happy. Next time do your research before hand.

Your one of those people that go to McDonalds and sit in the drive thru 10 minutes trying to decide what you want. They have Hamburgers, and chicken. Decide what you want on the way there. No matter what you decide you will never be happy.

Completely agree! 4850 beats 8800GT in about every test possible and is priced at $199.

That is the motherboard I have rgasaunders, but you can get by with the P45 based P5Q Pro for $149.

What have you tried with your board yet? Or are you just nervous because people are telling you the board sucks and Nvidia chipsets have problems?

If you already bought it , give it a shot. People give SLi a bad rep, when in fact 90% of those giving that advice have never done SLi before.

Asus have just released a new BIOS update which fixes a few things, including the evil video corruption bug. version 0601 (I think you'll have to input your motherboard into the site)
Also, how is your Northbridge? I'm considering buying this board but I've heard it gets quite hot?

I'm gonna stick with it. An 8800GT might be beat by a 4850, but not in SLI vs CF in most games (other than COD, etc.).

Thanks for all the advice.

I haven't had any issues yet...

And by the way, I already know what I want when I get to McDonalds as I order the same thing every time.
