SLI/GPU NEED HELP

[MCCOPRA]

hi,

 

First and stupidest question Can i SLI a 1080 with 1070 ?

 

also is it better to sell my 1070 and get a 1080 or just get another 1070 for 4k gaming.

 

Thanks5

No. The 1080 must be paired with another 1080(and the vRAM amount must be the same), and vice versa with the 1070. As far as I'm concerned, you will get more value by using two 1070s versus a single 1080.

Above is correct. But overall single card solution is prefered, since SLI has drawbacks and can cause a worse experience despite having more fps output (think frametimes, gamesupport, related hickups). So it will depend much on the games you play. 4k is a scenario where it makes sense, however would personally still go single 1080 and dial back some settings if and when needed. Depending on settings you can also do several games nicely on a 1070, but you will overall talk medium or lower settings range for more demanding games. But some are also still high etc.

I strongly disagree with Godlygamer23; a 1070 SLI might have the possibility of providing better value than a 1080, but, and this is a big but, only when the game or application you are running supports mult-gpu setups. It's not automatic and must be implemented manually by the developers of the game for each title. Often for smaller game titles or poorly coded applications this will not be the case and your second 1070 will be utterly wasted. 

If you sold your 1070 you'd need to take into account the lost monetary value of trading the card for a 1080. If you upgraded to the 1080, though, you would then have the possibility of moving to SLI if you really need the extra horsepower, however if you moved to a 1070 SLI and realized you can't get enough gpu power you'd have to upgrade the 1080 (or whatever's higher) anyways.

 

EDIT: Mist-understood the question asked, changed to make sense

He is not incorrect in what he says, and he answers to what the OP asked.

 

That there are more things to consider for the OP with regards to multi GPU setups with gaming is a different story though I also strongly recommend single card solution. But guess thats made clear for him in our posts

What you're saying is true, but even in the situation of not being able to run SLI, the value goes towards the 1070 setup. If the user is going for raw performance and cost is not an issue, then by all means, go for the 1080 setup. At this point, the 1070 that they currently have will be sold at a loss, and something they will need to deal with. And for what? A little bit better performance when they could just add another 1070 and be largely done with it? Even in the situation where the second card is hardly utilized, the poor utilization may result in still superior performance over a single 1080.

 

The performance difference between the 1070 and 1080 is about 17-20%, while the cost difference is closer to 40%(using Newegg as my source, and USD as my currency).

Thank you all for your posts did the calculations and getting another msi gaming x 1070 to run sli setup.
