Oh dear... unsure of mobo choice for new build now...

After finding reviews for the motherboard I would be getting with my CPU (via combo deal from Newegg), I was put off by some of the things apparently going against it -- bad PCI placement/spacing, questionable BIOS, questionable performance overall (despite being the "World Record OC King"). So I got to looking for different boards that would fit my needs (Dualfire, preferably x16/16, able to comfortably fit twin 5870s). And because Newegg reviews are pretty bad overall, I figured I'd ask you guys: Which mobo looks best out of these? Or rather, could I get a rated list of best to worst?

ECS Black Series A890GXM-A $254.98 Unsure, x8?

MSI 790GX-G65 $259.98 x8

GIGABYTE GA-890GPA-UD3H $274.98 x8

GIGABYTE GA-790XTA-UD4 $299.98 x8

MSI 790FX-GD70 $302.98 x16

GIGABYTE GA-890FXA-UD5 $314.98 Unknown, x16?

MSI 890FXA-GD70 $329.98 x16

Now, my current choice (the Biostar TA890FXE) does support x16/x16 Crossfiring... and the next priciest motherboard (that comes with my CPU) that does so is the MSI 790FX, more than $30 costlier. Now, first of all, is the Biostar a bad mobo? Or are things just getting blown out of proportion? From these prices, it seems to be the cheapest x16/x16 mobo by a large margin, and while I'm not naive enough to think that higher cost = higher performance, I can't help but feel a bit worried.

Would my build suffer considerably from downgrading $20 to an X4 945 to afford a better mobo? Is the Biostar one competent and I'm worried over nothing? Does the gain of x16/x16 Crossfiring over x8/x8 trump my CPU performance? Can anyone suggest a better mobo/CPU combination (bearing in mind that I want some sort of quad-core AMD CPU and ability to Crossfire 5870s at x16/x16)? Yes, I am nearly at my budget limit with the $269.98 for the combo I chose at first (and yes, any new selection must fall close to this limit BEFORE rebates).

Thoughts on the matter?

theres only a 4% difference between a 8x/8x and 16/16 crossfire in performance so I would buy a much cheaper 8/8 mobo.

Also if you want to spend that much on a mobo anyway why not just get a i750 for 199$ and OC it to 3.6+ and get much better performance. That is what i would do.

If I end up overclocking, it will only be mild OCing. For the most part, I want a computer with good baseline performance. And I figured the x16 CFX wouldn't be worth an extra 50 bucks.



Okay, so if you had to choose between the GA-790 and the GA-890, which would you pick?
