Currently I have 2 GTX480s in SLI with triple monitor occasional use of 3D surround, I'm looking at upgrading... I trying to decide on many things as follows:
-Should I spend a bunch of money no a new card(ie. 780ti/880) and run with 480(Running Physx/3rd monitor)?
-Should I go all out with SLI new cards(lose all money)?
-Should I buy 2 middle-high grade cards in SLI(ie. 760/770SLI)

Should I wait for the 880 it sounds pretty awesome but expensive to with the pros of basically future proof for awhile but con of cost and performance vs SLI7xx Series?

Thanks in Advance:D ,

Rumors are that the first 880s aren't going to be TI and might not be as fast as the 780TIs. Specifically the memory bus might not be quite as wide.

Hi,

1) It's hard to say without knowing your CPU specs. I'd want an i5-4670K or similar to prevent a CPU bottleneck with high-end graphics.

2) Don't use a GTX460 as a dedicated PhysX card. Chances are it will bottleneck things. In general, you need at least 75% of the power of the main card (or cards) or they end up waiting for the PhysX card to finish its calculations. This varies between games and also depends if you choose Low, Medium, or High physics in the same game so i can't give a specific yes/no answer.

3) You don't specify which games you intend to play.

4) You can easily lookup benchmarks for what it takes to run a game at specific resolutions.

5) 3D at 60FPS per eye means 120FPS so if you want to game Crysis 3, at 120FPS, on a 5840x1080 resolution (three 1080p monitors) you're likely out of luck regardless as nothing can do that yet at max quality.

6) GTX880.
It's impossible to comment on a card without knowing the performance, cost, or date of availability.

Summary:
So it's hard to answer your question without more specifics. You'd basically have to specify a BUDGET and tell us exactly what it's for.

780ti all the way! I have seen them on sale from time to time for $650 which I consider a steal for how fast these cards are. I love my PNY 780ti OC, nice stock OC plus my own OC after that and cost should eventually go down when you are ready for a 2nd card for SLI.

1)Yea I was also thinking about CPU bottlenecking as I've seen it at 100% some times, I have an AMD Phenom II X6 1090T @3.4Ghz
Should I focus more on that or both...?

2)Also when you say don't use dedicated PhysX why is that because I have two cards and in a triple monitor configuration(Not 3D Surround) and when in that config it does not support SLI so my second card only runs at 1-2% would this card be faster at PhysX then my CPU under load?

3) Just some examples, BF4, BF3, GTA IV, GTA V(if it comes out), Euro Truck, Grid 2, Crysis also video and photo editing if that matters(Adobe AE, Photoshop CS6)

But another question do you think a 760/770SLI configuration would be better or to move more into the future and run 780ti w/480 for third monitor?

Thanks!

Thanks for your response and yea I have seen some good deals for such a power horse I'm leaning more towards that and saving some money for a CPU. :)

Replies:

1) You will have a bottleneck with your CPU as you've already confirmed yourself, so you really need to build a new system with an i5-4670K based on the amount you seem to be going to spend. Some would argue for an i7-4770K. I wouldn't with a single GTX780Ti but would with two of them.

The i7-4770K would be as high as 30% faster for converting video compared to the i5-4670K if the CPU is the sole bottleneck.

2) PhysX:
If the 2nd card isn't being used you should use it as a dedicated PhysX card. As I said, it needs to be (roughly) at least 75% the speed of the main card. If it's identical then there should be no bottleneck and you'll get higher frame rates than using only the main card for everything.

You can experiment with this yourself though I don't know if you can have it auto-applied per game? I have no option to do that but then I only have a single card.

3) Video Editing:
It's my understanding that none of the programs you mention take advantage of Graphics Cards beyond a certain point (i.e. GT650 is similar to GTX780). You can Google that but I had a link at some point.

The largest bottlenecks would be the CPU or System RAM. Which one it is depends on the program used, how much editing you're doing, and how large the video file is though I'd use 16GB as the minimum. 8GB is optimal if only gaming.

4) Games:
You can look up benchmarks easily yourself. They assume a good Intel CPU usually like the i5-4670K. You can find 5760x1080 benchmarks. Also, just HALVE the framerate for 3D.

GTAIV is an exception. It's coded strangely and runs like crap on even good systems. It gets locked to 44FPS and 52FPS depending on my settings, plus you can't apply anti-aliasing. GTAV however is very well done for PC (read about the development) so will be great when it comes.

5) SLI:
Don't even consider the GTX760 for triple monitor, and make sure you get at least 3GB per graphics card such as the GTX780 has. If you really want triple-monitor and/or 3D you need at least a 2xGTX780 setup with a good Intel CPU.

6) GTX480 for third monitor?

I'm confused, didn't you want triple-monitor gaming? You won't get that if you have one of the monitors on a GTX460 and the others on a different card. Here's how it works: http://www.guru3d.com/articles_pages/geforce_gtx_780_sl...

I'm pretty sure you can use a 1x or 2x setup with three monitors as well but you can look into that. I really wouldn't go above 2x as there are a few issues with 3x.

Anyway, there's no good reason to have a GTX460 sitting in any system just to run a 3rd monitor. Even if you needed another card which is unlikely, you'd be better off with an inexpensive HD6450 512MB or similar just to do basic tasks because otherwise you're dumping more heat and noise into the PC than you really need to.

I'm also confused by the 3rd monitor comment in that are you thinking about gaming on only TWO monitors? If so, that's a bad idea as the gap between two monitors is right in the middle which sucks.

The GTX780 supports four monitors I believe assuming you have monitors that support all the outputs. If you don't have DisplayPort it would likely be 1xDVI, 1xDVI, 1xHDMI (HDMI->DVI adapter if needed).

do you really need immediate upgrade? if not then you might want to wait for maxwell although there is no solid info on release date yet. if you must have it now try looking for 780 6GB (SLI) or upcoming 780Ti 6GB (also SLI)

personally i think whatever coming up to be 880 will be end up faster than 780Ti. GTX680 only have 256 bit memory interface but the card still end up faster than GTX580 which have 384bit memory interface

I would go with 780 SLI. They are just a tad behind 780tis in performance and they've dropped below $500. You would save a lot getting that instead of 780ti (over $700 typically) with minimal gain over regular 780. Over $200 increase for small performance jump to me is an easy choice. Good luck with whatever route you go.
