7990/ 7970 trifire replacement for 3 monitor set up 5760x1200

[dcdave78]

I max out my cards for GPU memory when gaming even in BF4. 7990 / 7970 in trifire

I would assume I need more GPU Ram. So my thoughts were based around this for future upgrades.

What would be the best solution. Btw i have a custom water loop where video cards are watercooled as well. So I want to stay with that set up moving forward.

R9 290x 8gb x 2 (Have a line on two cards with waterblocks installed)

titan z ( same I have a connection on ebay with waterblock installed but only has 6gb per core)

titan x ( has the most ram but expensive as heck)

Is their any options i may have missed? is there a sweet spot for this resolution 5760x1200

BTW all system specs listed below

i7 4930K @ 4.6 GHZ
Asus Rampage Black edition iV
16 GB Dominator DDR 3 ram 9-9-9-24 (1600mhz)
Samsung 840 EVO 500 GB
XSPC Water cooling loop with three 360 rads with Rasa Copper edition CPU block
7990 / 7970 trifire
Corsair 900 D case
1200i Corsair power supply

I would go with the 290x's as a titan x (for the price) is a bit overkill

 

[dcdave78]

I just found four R9 290x 4GB with waterblocks but is this enough ram for 5760x1200?

 

[Kevern_11]

I would say so, 290x's are a good card and have enough vram for several monitors.

 

[dcdave78]

do you think my power supply would be up to it?

 

[Kevern_11]

I don't think. 290x's Are Pretty Power Hungry, But Im Not The Best With PSU's.

 

[jerdle]

Why not use 2 R9 390s or R9 390Xs?

 

[dcdave78]

390 is the same card as the 290 really

 

[jerdle]

The 390 generally outperforms the 290X

 

[dcdave78]

by what percentage 5% at best?

If you haven't already, go for whichever you can get for the lowest price, 8GB 290Xs, 390s(there are dual boards available if that's your thing), 390Xs, or if you want, 980s, though their RAM feels like it might be a problem in the future.
