Selecting GPUs for a 7680x1080/7680x1440 build

post #1 of 4

Hi all smile.gif

So I'm on the cusp of my first full computer build. I will be using this for heavy video editing, rendering, as well as game design and gaming. I love multitasking across an array of screens, and so this lead to a 3-monitor setup plan. Since this PC is being built with powerful components I decided that I shouldn't leave it by half measures, and go with a large size of screen. This lead me to 27" 2560x1440 and 29" 2560x1080 monitors. I actually have a slight preference for the 1080p monitors as they lend themselves well to multitasking, albeit coming at the cost of a premium price. I've also used both sizes on friends' machines and this has pushed me towards the 1080p. I desire good colouring as well as a monitor that can overclock to 96Hz and even 120Hz, just to fit my graphical nitpicks.

Before I go further, I'll show you my planned build. The higher prices are the unfortunate side-effect of living in Australia. Well, that and the constant assault of deadly creatures:
CPU: Intel Core i7-4930K - $674
Motherboard: MSI X79A-GD65 (8D) - $331
Memory: G.Skill TridentX 32GB (CAS 7, 1600MHz) - $401
Storage (SSDs): 2 x Samsung 840 Evo 250GB - $376 (Raid 0 initially)
Storage (HDDs): 2 x WD Caviar Black 1TB - $190 (Raid 0 initially)
Case: NZXT H630 or NZXT Switch 810 - $179 or $199
PSU: SilverStone Strider Gold Evolution 1200W - $275
Sound Card: ASUS Xonar Essence STX - $167

Current Total: $2593 or $2613

To further explain, I will be creating and installing a custom loop on this build, and it is the vanity vs. sound deadening that is splitting me between the H630 and the Switch 810, although I am open to alternatives should anybody have any suggestions smile.gif But onto the main point. The screens I plan to get are the Yamakasi 290IPS Panorama screens. They retail for about $525 on E-Bay (again, AUD) and the three of them set me back approx. $1600 if we factor in purchasing good cables and maybe lucky deals/bargaining. These would make for a 7680x1080 display. My other alternative is the QNIX QX2710, but to be honest my heart is set on the Yamakasi, and I have brand faith after seeing and using a Catleap for some time.

Total Outlay so far (incl. expected cost for WC loop of $1000): approx. $5200

SO, with this in mind, I'm looking at my options for graphics card. I know I've already thrown the budget into a black hole for this build, but I suppose I want to spend effectively on the graphics cards. So, my question to you all is what GPUs should I get. I've been looking into a 3-SLI setup of EVGA 770 Classifieds, but if it would be possible to push that with two 780s or the like, I'm open to it. My brand preference is EVGA, but that won't mean anything in the wash. In the end, my hopes for the cards are as follows:
  • Preferably 2 DVI Dual-Link outputs, but one is fine (to explain, these monitors only take dual-link DVI for my purposes, and converters from DisplayPort are active and may reduce quality, single means 3 of the card)
  • Ability to run my setup at a minimum of 60Hz
  • Can convert card with a waterblock to add to a powerful custom loop

So my questions to you lovely people is what your thoughts are as to what GPUs I should choose? Should I make changes to some parts of my build? And any other comments you have. I'm open to criticism, and I would love some help as I had been recommended to ask here and what I've read promotes you all as very knowledgable smile.gif This beast will soon be mine and I want it to be brilliant biggrin.gif

Regards,

Koios

Hello from Brisbane too!

What are you willing to spend on the GPU?
Did you pick your hardware yet?

I face the same question at the moment.

I am deciding between

2 x GTX 780 in SLI
2 x R9 290X in Crossfire

Unfortunately I cant afford 2 Titan's in SLI at the moment and the R9 290x stock coolers are terrible.

Hi,

I'm willing to spend up to $1200 on the GPUs, but I want to avoid overspending. I haven't been able to pick up the hardware because I forgot about christmas presents and some bills. So a little while longer before I bring this beauty into the world.

Personally, I'd suggest waiting for the custom coolers to launch for the 290x series, as in many cases they kick even the titans out of the park

I advise you the same but I doubt I can tell you anything you don't already know smile.gif

2 x R9 290X for about $1299 at Umart.

What are your other options for intensive graphic manipulation at 7680x1440 for $1200.

3 x Nvidia GTX 770 4GB $1330
2 x Nvidia GTX 780 3GB $1258
3 x AMD R9 290 4GB (potentially unlockable to x) $1425
2 x AMD R9 290X 4GB $1298
2 x AMD 7970 VAPOR-X 6GB $1330

The above are current Umart prices.

Many people waiting out for the R9 290X with aftermarket cooling.
The drivers will only get better from here on in........also there is mantle optimization to look forward to.
I have not had the opportunity to use this card yet but there are plenty of owners complaining about heat, noise and black screens.

The only reason I am still leaning toward Nvidia 780 is Skyrim optimization but the 3GB Limit is frightening smile.gif

Let us know what you decide!
