Yeah finally i changed my mind about 550 and got 720.
I didn't want to go with a dual core in case of non unlocking..
I purchased a used 720 for 100$ and if everything goes bad ( i hope not ) i will have a tricore..
I don't know what would be the best mobo?
Asrock 770 series or the Gigabyte 770?

The Gigabyte. A better quality board. To unlock it on the Gigabyte set the ACC in the bios to Hybird and set all cores to auto or all.

Doesnt matter...20 lanes is 20 lanes no matter how you split it up(Whether it be x16, x4 or x8,x8,x4)Plus if you are going crossfire you wouldnt want to go with a 785 chipset in the first place(its more or less just a 770 chipset with integrated graphics anyhow)

Also, ASrock is the low end sector of asus, Asus wouldn't use their low end sector to compete against themselves.

The asus board you linked too had one 16x and one 4x. With crossfire it would only be 4x/4x. The ASRock I linked too had 16x/8x/4x, thats 28 lanes VS 20. Crossfire is 8x/8x. The Asus board only has 2 slots.

The highest end ASRock is way better than the lowest end Asus. It's not competing, just increasing sales for those who don't know.

Your wrong on both accounts.

A 785 chipset only allows 16 PCIe lanes for Graphics.

The Asrock puts a Switch board for Switching 8 lanes to the second slot. If you have the switch board turned to 16 lanes for the main slot the second slot is dead. Which gives it CrossfireX support. But not Tri C/F. The third slot gets its 4 lanes from the southbridge and cant be used as a third slot for Tri C/F.

Lastly it’s down to expansion slots and the additional chipsets the board uses. Thanks to the 785G's CrossFireX support, ASRock has taken advantage of this and included a total of three PCIe x16 slots. 785G only has 16 lanes for graphics, so you either have a single x16 slot or 2 x8 slots for CrossFireX mode. (The last x16 slot is simply an x4 slot running off the Southbridge).
ASRock has been given a black mark also on its implementation of CrossFireX switching. Many other companies use digital switches to switch the PCI Express lanes, ASRock has gone and used a switch over paddle card, similar to the ones used when SLI was first released. This makes setting up CrossFireX a bit more of an effort if you already have one card installed. You have to take this video card out, switch the paddle around, reinstall that video card and then install the second video card... annoying to say the least.

The Asus has a main X16 slot. It doesnt need a old switch board, it electronically switches 8 lanes to the second slot if its occupied.

2 x PCIe 2.0 x16 , support ATI CrossFireX™ technology (at one x16 or dual x8 link)

http://usa.asus.com/product.aspx?P_ID=vk9Pqxby9MjO0WHm

In CrossfireX both boards run in 8X/8X.

It says right on ASrock's site that the board does 3 way crossfire.


You also linked to a different and more expensive board than he did. It's even a 790x chipset not 785g.

http://usa.asus.com/product.aspx?P_I...rnR&templete=2

Here's the one he linked too. Crossfire on that board is 4x/4x.

Here's a like priced ASrock board ($5 cheaper actually)

The boards I linked to in my first post had nothing to do with C/F. It was the quality of the boards.

Somebody else brought up a link to the other Asus board.

http://www.tomshardware.com/reviews/...rd,2441-3.html
This Review does say the Asrock can be run in Tri C/F at 8x/8x/4x. But who in their right mind would pay for three cards to run in 8/8/4. its a gimmick.

I,m talking about the quality of the boards, not the little extra bells/flashing lights.

Which do you think would be better? To add a X4 slot or put a better 10 phase power setup on the board. I wonder which one is cheaper to do, Hum!

Would you rather have a ash tray that played music when opened and a air freshener on your rear view mirror. Or a better engine in your car?

I know, but the topic of posting was about comparing the best 785g board both asus and ASrock had to offer. In post 51 I quoted the board you linked too, not even being a 785g board.
BTW, I can't overclock any CPU I have better on my gigabyte board that I did with my $55 asrock board. They both hit walls at the same clocks.

Then you say all this crap about the third 16x slot on the ASRock and how I'm wrong that it's not for 3 way, when it says 3 way Xfire right on asrocks website. So whatever.

I was talking about the two boards I linked to in post 33. In post 36 you said wrong because of the crossfire of the Asrock board. My point didnt having anything to do with if a board could do C/F or not, its the build quality of the boards.

In post 37 g25racer gave a link to the 790 asus board.

In post 49 you said the Asrock was 16/8/4.(28) lanes. In C/F the board would run 8/8/4 (20) lanes. The first two slots share lanes, the 3rd. slot gets 4 lanes from the southbridge.

The Asus has a Stand alone X16 slot. The second slot get 4 lanes from the southbridge just like the 3rd. slot on the Asrock. In C/F the Asus is 16/4 for a total of (20) lanes.

In post 53 I said I found another review that said the Asrock could do Tri C/F.

My point in all this has nothing to do with if a board can do C/F or not, which seems to be pulled that way to distract from the point. I would not buy either board for the C/F.

My point is the quality of the boards. Asrock uses lower quality PCBs and components .
