4GB or 8GB VRAM for 5400x1920?

[KBuckets]

Hello everyone!

 

I am going to be making a 5 monitor Eyefinity setup with five 1080p monitors (5400x1920), and I am wondering which graphics card setup would be best.

 

 

My options are (but not limited to):

 

Two R9 295X2s in Crossfire, for a total of four 4GB 290Xs across two cards (two card scaling)

 

or

 

Four 8GB R9 290Xs in Crossfire, but it will be across four cards (four card scaling)

 

 

I'm wondering if 4GB will suffice for that resolution, because I don't know how well the scaling will be with four graphics cards.

 

 

Thanks!

Pack on the 8gb, i'd say. 

[Tedster]

Yup, I'd go with 8GB.

[david cassar]

Don't get 4 GPUs. Scaling isn't that great especially after you add more than 3. At that res get two or three 8gb r9 290x.

[TheKDub]

4GB should be fine, though id recommend 8gb to be safe.

[zappian]

8 GB , unlike some people here think the 290x actually can use more than 4 GB of vram properly.

i'd go for 4 cards, only for the fact then you'll have 4 coolers instead of 2 coolers keeping things cold.

The R9 295x2 is infact 2 cards on one board. The only difference between two of those and 4 r9 290x cards is the vram. I would go with three 8gb cards since 4 way scaling is just not what you want.

8. If you run that resolution with 4 and it will probably get maxed out really fast in most modern titles.

I'd wait for the 390X. That resolution will put too much strain on current memory bandwidths.

As i recall 295x2 is two 4 gb 290x for a total of 8 gb of vram. As gpu vram doesnt stack it will still be a 4 gb card in reality. You have fallen victim to marketing

Two 8gb 290x cards would be the better option.

What mainboard chipset do you have? If X79 or X99 with the 40 lanes PCIe 3.0 CPU I´d go for a real 4way CF. If you don´t have that go and buy 2 R9 295x2 otherwise you will bottleneck 4 cards. Even though you won´t need a 4way for 5x1080p. This is just a bit more than 4K to drive and 4way isn´t very beneficial in terms of scaling.

Wait for the 390X to debut

may I ask what you want to do with that setup?

16:9 screens in pivot are kinda akward.

That's not how it works. It doesnt matter how many cards are in your system. What matters is the number of GPU cores, and you still have 4 whether you use four 290xs or two 295x2s

The scaling is the same

[Wadu436]

That are more pixels then 4k so i'd say get 8GB

I've only got Z97 actually

Mostly gaming with this setup and extreme productivity haha

This, crossfire scales the same wether gpus are on the same card or not. For high resolutions, I'd wait for the 300 series from AMD.

[KBuckets]

So sounds like 4-way scaling really isn't great, but I should have 8GB of VRAM.

 

Should I wait for the 390X and then an 8GB version or should I just go with three 8GB 290Xs?

[1-800-Taco]

8gb. 4gb is good for 4k iirc but I'm pretty sure it's not enough for 8k if you're gaming

2x 295X2s would also suffer from 4-way scaling since each 295X2 is a crossfire setup. Go with whatever is cheapest. I think 3x R9 290X would do fine, not many games scale well with a fourth GPU.

[i_build_nanosuits]

good luck running anything more than two R9 290X in the same case buddy
