Help wanted (searching for new mobo).

So here's the deal, I've decided to buy a second Radeon HD 5770 for my rig, but my current mobo only comes with one PCI-E 2.0 x16 slot, hence the need for a new mobo.

So, I'm looking for a CrossFire ready mobo (that can get the most out of 2 5770s) that uses DDR2 RAM (I really don't feel like buying new RAM).

This is the only one I've come across with so far:

Newegg.com - MSI 790XT-G45 AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard

Would that board be able to get the most out of 2 5770s?

Hiya pal

From personal experience I would say no ....
I was in the same boat, but I had the advantage of running 2 x 5770's in crossfire and because of my job I happened to be able to test a single 5850 aswell, from personal benchmarks I found that a single 5850 out performed 2x 5770's in crossfire quite considerably.

So personally I would advise that you leave you MB as is and purchase a single (larger than you have card) you could always sell your 5770 and recoup some of your cash towards your new 1 ;)

I don't know man.

Lately I've seen some very strong raw numbers from 2 5770s crossfired.

In fact, look at what Steven Walton from Techspot had to say about the performance of two 5770s crossfired (when discussing 480 SLI vs 5870 CrossFire):

For the lower-end cards we find it harder to go past a pair of Radeon HD 5770 Crossfire graphics cards as they outpace contenders such as the GeForce GTX 470 and Radeon HD 5850.

That seems pretty good to me =).

But getting back to the topic... Would that board get the job done? (crossfireing 2 5770s).
