Hi guys
please tell me if the SLI/Crossfire of GPUs in (x8 x8) PCIe3.0 slots can handle (7680x1440)
Because most of today's z87 motherboards' SLI/Crossfire are in x8 x8
I know it is because of The CPU lines , but could it handle it ?
 
Solution
At this point in technology GPUs only currently need 8x/8x lanes in SLI/Crossfire, having both lanes as 16x/16x is paying extra money for maybe 5% increase in performance.

Now what your actual question is, it depends on the GPUs you have, not the lanes.

If you're running SLI 7850s you could run that resolution, but you couldn't run any games.

You never stated the usage of your PC. So if you're using that resolution to program or something not graphically intense, your GPUs don't need to be that beefy.

But if you're looking to game at that resolution with 60+ fps on ultra, you're going to need quite a few 290xs or 780 Tis

8x is currently completely acceptable and will handle anything you throw at it, given you have right GPU(s) to support what you're trying to do.

lp231 recommended the WS motherboard because it has the ability to run quad SLI as 8x/8/8x/8x. Most consumer motherboards will only support either a single card at 16x, or dual cards at 8x. There are a few boards that can support three way 8x PCI-E lanes, but most other boards only support 16x/8x/4x, or 16x/4x/4x. So having the workstation motherboard gives you enough 8x lanes to support your resolution.

Splendid


When a motherboard is label as "Workstation" it doesn't mean it can't be used for gaming. If that is true, does motherboard without the word "gaming" on it can't be used for a gaming as well? No. That board is label as workstation because it got extra features, users in a professional environment may find useful like the internal USB plug for dongle keys. Overall almost all current Asus boards are similar to one another.
You had a concern about will dual graphic cards be capable running at that resolution at x8/x8, and the answer for that is yes, it's able to. But like some of us here, there are those who wish that Z87 can run dual cards at x16/x16 instead of being cut by half to x8/x8.
So this is when the Asus Z87 WS comes in, It's one of the Z87 boards that is capable of running two video cards at full x16/x16.
It's a suggested board for you and others who passed by to check out, and that not all Z87 boards cuts down dual video cards setups to x8/x8.
Want to grab it or not it's your choice
