Help me choose which GFX card to get

post #1 of 5
Thread Starter 
Okay, I have two GTX 760's in SLI which scale great and perform amazingly... but I also want to go to triple monitor gaming in the future and I am going to be playing BF4 which has recommendation of 3GB of VRAM (my 760's only have 2GB)

Right now I can get a used EVGA SuperClocked GTX Titan 6GB (originally $1,069) for $820 OR can I just get a third 760 since they seem to be performing so well? I'd feel kind of stupid buying the Titan for twice the price and less performance. GTX 760 SLI has been outperforming Titans in a lot of games. But would three 2GB 760's be able to play triple monitor gaming & BF4 and future demanding games? What should I do?

Maybe just get a third 760 and do the real upgrade next year when Maxwell comes out?

Would it be possible to keep my two 2GB 760's and then get a third 4GB 760 and then use the VRAM from that card as my primary card or something? From what I've heard if you have 2 cards both with 2GB VRAM they dont double over to 4GB correct?

If thats true can I trisli two 2GB 760's and one 4GB 760?

Can you quad sli four GTX 770's?

I wouldn't put too much faith in the 3GB recommended VRAM limit for BF4. I also wouldn't do anything right now -- not until you can actually buy BF4 and run it on your current rig with two 760 in SLI and see how it performs. If you want more horsepower, and your motherboard supports Tri-SLI, then adding a third 760 for that third monitor seems like it would make the best sense given your current investment.

If you Tri-SLI two 2GB and one 4GB card together, you will be limited to 2GB usable VRAM. The VRAM is mirrored on all cards in SLI, so the least common denominator sets how much you get to use.

Greg

p.s. You're probably going to need a new PSU to run Tri-SLI. Your X79 is definitely ready to go!

As a triple screen gamer also, you have to consider the VRAM and GPU grunt together. If we take Crysis 3 for instance, With all the bells and whistles on, I noted 4.8GB of VRAM being used at 5960x1080 but of course at that res and on SLI Titans, it was far from playable with an average of 25fps.

Titans are great cards but if you can't justify the price, I would stay away as they are expensive for what they are. The 780's can be clocked passed a stock Titan with little effort and can save a few bucks. As for the 760's, they will work great in SLI over 3 screens if you don't mind notching down the settings a little (maybe lose some AA). Also, I am not sure if the 760 can do Tri-SLI but will look to confirm and in honesty, it would have been better to have 670 4GB before considering Tri_SLI.

AMD are just about to release their new GPU's (statement being made on the 25th of this month), so best to wait it out. I loathe AMD biggrin.gif but they have improved massively over the past few months, so depending on price, it could pay to go that way.

My thoughts anyway smile.gif

Edit:

You can do Tri-SLI smile.gif

Yeah I was thinking sell my two 760's and then buy three 4GB 760's until Maxwell comes out next year... I don't really know anything about AMD products and I'd rather stick with nvidia tbh. But if you guys think I can get away with 2GB VRAM then it would be so much easier to buy a third 760 like the ones I have. What kind of wattage would I be needing for three 760's along with the rest of my rig? 750W has been doing me just fine for the two cards currently. I'd also like to eventually tri-sli maxwell flagship cards (possibly even quad) probably by summer next year. So maybe future proofing the PSU wouldn't be a bad idea.

A good 850W PSU should be enough to cope but I would be inclined to go for a 1000W. I run an XFX 1050W black edition and it is a Seasonic build (top quality). If you are looking for quad cards in the future, go all out on the PSU and look for a 1500W quality brand. It is better to have more power if needed over just enough (who knows what we will be doing in a couple of years?)

The 2GB is fine but again, this comes down to your own personal settings and if you are happy to notch them down for some AAA games (Crysis 3/BF4 etc), then stick with those. If you want the best settings available, I feel 3GB is a must as a minimum and even then, touch and go across 3 screens.

It would probably be best to see how your 2 760's cope with 3 screens and then decide from there. It will only be the odd newer game that needs settings toned down and even then, frantic games like BF3 you wouldn't notice (if you was looking at the scenary, you would be dead) biggrin.gif

Good luck and thanks for the rep. Just need a bit more for selling smile.gif
