SLI or Crossfire?

[Ramdomico]

I don´t know if i choose:

Crossfire -> MSI R9 290X Lightining

or

SLI -> EVGA GTX 780 Ti Superclocked ACX

Or even if i pick a single EVGA GTX Titan Black or Sapphire R9 295x2... I think ill be playing most on 1080p, 4K is for the future lol
And i also would like to know if a Asus Sabetooth Z97 is good for a Crossfire or SLI.
Thanks guys for any help xD

Nothing to see here folks.

What types of games are you going to play? and what screen do you have or plan to get?

 

[GforceD]

Crossfire easier to use allows different AMD/ATI Card to be paired up witrh each other and crossfire boards are cheaper.


SLI probably better proformance wise and more stable in 3-way SLI configurations.

But as this CHART shows one Nvidia 780Ti is much more cost effective than 2 x ATI R9 295



Z97 Board Review


As you can see with motherboards profomance is almost a non issue among boards of the same chipset so the best you can do is choose one that fits your needs and price range.

I think all boards support both Crossfire and SLI these days.
It more boils down to what you want to spend on graphics cards, and their use

With the amount of money you're willing to spend. 2x780Ti's would be less hassle for a bit more dough. SLi in your case.

No! Most boards with with dual pcix support crossfire, SLI supported boards are a little more pricey.

On that note most SLI or Crossfire have PCIx x 16 slot and PCIx x 8 slot thats why the newest 97chipset are better
since they can support 1 PCIx x 16 and 2 PCIx x 8 so you get the most out of 3 cards.

Single card ftw.
SLi/crossfire will always be a pain. Its not as bad as it used to be but it still gives hassles in some games.

Well I doubt he is looking at R1000 boards, hence the gaming board and cards he is looking at.


I still would like to know what he is going to play and what screen he has/planned. As this will influence what would be optimal

Honestly I'm disappointed in crossfire/SLI.
For some reason I don't see that big a performance increase in using crossfire (anything from zero improvement to at most 30%-ish).

Is it that developers just don't give a hoot about x-fire/SLI? Is it a limitation in directx? Could the ram on the graphic cards be the limiting factor?

It depends on the game, if it is supported. 30% seems too low tho
For instance Battlefield 4 one 290x gave me 90fps average. With two I get 160fps average, sometimes see 200 where it caps

on the other hand watchdogs runs worse in Crossfire than with a single card so need to disable it.

Then you're perhaps just playing badly optimized games!

Like with my 2x GTX460's I get around 80% performance increase in the games that I play: BF3, BF4, DOTA2

Unfortunately SLI/Crossfire setups doesn't increase your total VRAM, so you may run into VRAM issues when you wanted to go for SLI/Crossfire to run a higher resolution like 4K. Like my 2x GTX460 1GB cards are struggling in some games to run at 2560x1600, because the game only has 1GB of VRAM between the 2 cards and not 2GB

Running 2x GTX780Ti / R9 290X is absurd for a 1080p setup, unless you're gaming on a competitive level where every extra FPS counts.

I guess its the resolution that I'm running (2560x1440 @ 110Hz) thats affecting the frames.

Or if you have a 120Hz screen or higher and need the power for that..

A single EVGA GTX 780 Ti Superclocked ACX is perfect for 1080P gaming.

In fact i was watching this yesterday.

PS:it was a regular 780ti, not SC.
