AM3 mobo that supports a real tri/quadfire setup?

post #1 of 3
Thread Starter 
So I just spent all night installing my new ASRock 890GX EXTREME4, moving all kinds of crap around. Finally done with it, can't wait to toss in a bunch of video cards, except...

The way the board is laid out unless you have some tiny midget GPUs, it's basically impossible to use lanes 2 and 3 (the PC Speaker and case buttons block lane 2, and the SATA connectors block lane 3). So... yeah, awesome, any videocard that's like more than 9" or so is basically worthless. Also even if I could fit the cards in they're basically sandwiched completely together so that there'd be almost no airflow, ugh. In my eyes this board is a piece of garbage.

So, since I'm apparently a terrible judge at picking out what mobos are useful, I'm curious if anyone has any recommendations of AM3 mobos that could fit 3 or 4 normal sized video cards, with a reasonable enough amount of space between them that they wouldn't all shoot to a billion degrees and melt my room the second I started using them.

Any help is appreciated (other than just listing 3 / 4 PCI-E lane boards, since obviously that isn't going to cut it), Thanks!

EDIT: I'm looking at the MSI 790FX-GD70, how is this board? Any good? Any problems that will make me want to smash it with a bat like the ASRock?

it is not an option for motherboard manufacturers to space the pci slots at any distance interval they want. that is the same spacing on every other board on the market.
watercool the gpu's. throw a decent loop on your cpu too

It's not all the same spacing, though admittedly they won't necessarily use the same expansion slots depending on how it's spaced. If I went 3 gpus I could do it with 9 expansion slots, or 4 gpus with 11 expansion slots assuming the MB spacing is 2 bays then a skip. I think the MSI I mentioned is spaced that way, but I'm not 100% sure, which is why I am asking.

I would WC except that the cost of WCing 4 GPUs and a CPU is very prohibitive. I know it sounds like I'm mr. money bags if I'm going to be running 3 or 4 GPUs, but I can't really imagine dropping $700+ on a pita cooling system. I could spend like $100 more on a large high airflow case, which makes more sense to me.
