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.

Gigabyte has the best customer support VS Biostars which barely exists.

Beware of lesser brands.
They might be cheaper but you'll wish you paid more when your board dies 6 months from now.


use newegg's compare feature to narrow down exactly what you want.

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?
