Crossfire 7870

[Manos]

It has been some years since then amd 7th series came out and my old gpu 7870 is struggling to keep up with the modern titles. I think the best scenarion would be to upgrade my gpu but i lack the money to buy something that will cover for the next 3+years. I am wondering though if its worth to crossfire my 7870 with another. In ebay i have found used card as low as 30euro. Do you think its worth it? Will i see difference on my fps.

i5 4690.  8gb ram. psu 720w

for 30 bucks its hard to go wrong

if your psu has the necessary pcie cables then go for it

Don't really.... 2gb isn't much, and will bottleneck.

 

Crossfire with weak cards was a BAD idea 10 years ago, and this did not change. You might only get +30-40% more performance, maybe +50-60%. 

Plus a ton of problems.

But yea, 30 bucks isn't much, and you should get this back if you resell it, in case it doesn't give you enough boost.

 

 

What Games do you play? Some will require more than 2gb of Vram. so even if you crossfire 20 7870 together, they would not perform well ^^

XFire is your best option then

Have fun with your improved performance

umm i play everything low demand games like lol ksp to high demand like bf1 witcher etc...

 

[Darkseth]

those games might work, they don't need much Vram.

 

Stuff like CoD infinite Warfare should stutter (since it needs Low textures already when you have 4gb :P)

 

But yea, might work. Just try to keep the fps above 60 at all times. The lower the fps, the more microstuttering should be visible ^^

yeah i know it cant share the vram... Would be compatibility issues if the cards isnt the same brand and the clock is the same?

no

even if the clocks are different they will run at the slower one's speed IIRC

no game requires more than 2gb of Vram to run otherwise cards like the gtx 1050 (ti) would barrely sell themselves.

are you OK

 

Some games need over 4GB when textures and other settings are high.

[Darkseth]

You have tried every game there is?

 

Well, enough people think you don't need more than 4gb of Vram to run a Game at LOW texture settinsg without stutter.

And there is CoD Infinite Warfare... Can't even run stutterfree on a Fury X with HBM, because the Vram is not enough for Normal texture settings. Need to set it on LOW ^^

 

Cards like the 1050 are not made for AAA games. And 1050 ti has 4gb^^

 

2gb today is the absolute bare minimum to be playable for most games. However, i would NOT hold my hands in the fire and say there is no game, that requires more than 2.

just because they would use more than 2gb doesnt mean you have to have it. MY brother used to play BF4, BF3, CS:Go on a gtx 560 1GB in 1080p with more than 60fps, so i dont think your point doesnt represent the general rule

The less valid point is yours. I said some games. You tried to generalize and said no game, which is inherently not true.

because the few games that wont run on that are generally so badly omptimized that you couldnt even run them on a average gaming rig

So GTA V and the Witcher III are 'unoptimized' to you?

witcher 3 yes, gta v works fine, my brother played that on a gtx 960 2gb in 1080p so its fine
