Hello folks, I recently picked a bundle of a 8320 and an Asrock extreme 3 970 mobo and my question is the following ; right now I have a 7870 core edition XFX card, it runs most of my games at highest settings with no problemes however I'm curious to know if I'm better off with a more powerful single card or to just buy another 7870? The motherboad run on 16x/4x I belive.

Thanks!

Well that decision is then on you. :)

Unfortunately there will always be people on here that argue about even the most basic stuff.

Just the fact that X8 / x8 exists and that VERY few people suggest going Xfire on x4 should be a nice indication.

A simple Google search can tell you exactly how many people made the mistake of doing just that.

No problem with it. almost the same now with my asrock z77 extreme 4 (x8 and x8)

First off, the HD7790 is a mid range mainstream card that I would not even Xfire in the first place.
Not really comparable, or what?

Third almost and tried are very unspecific? WHAT was the difference? Because frame latency would have been high, lowest recorded FPS would have been lower than with a single card. Highest would be higher but average would look worse.

Soooo...

I get your point Novuake, but I'm seeing it that way; either route can be a hit and miss because crossfire 16x4x doesn't seems so bad however there is in fact a performance loss, but on the other hand is spending 300$ for maybe a 10 fps increase is a better idea? I'm not used to running multiple monitora but that is something I would like to do in the future.

A simple Google search brings a mixed bag of results. Would you say that a 780/780TI would beat Crossfire R9 280x on 16x/4x even with performance reduction?

I would take a situation where even the 2nd card is at 75%, if it outperforms the single GPU solution of a 780 or even 780TI then I would do it.

I'm sorry for sounding stubborn as fuck, but I really don't want to swap out my motherboard

Lol... you lose like 5% performance max on 4x lane.. what you just said is insanely wrong

Get the G1 970, much better option than adding a second 7870..
