I just recently exchanged my gtx 680 for a mars 760. It was on sale on newegg for one day for 569, and it normally is 649. However, for 700 dollars I can pick up the 780ti. I am planning on buying another card very soon. Sadly, when I play I've noticed random black flashes on my screen while playing. Brand new card too :/

So my real question is I know SLI scaling is odd but I'm wondering if the black flashes (if its a faulty card) should I return the card for another mars 760 and go SLI or just return it for the 780ti and then in a few weeks just buy another one of the cards I've just purchased to run SLI

I really am not too happy about the black screens, also seeings I have 4 monitors and only play on 1 atm. ( It seems I have to disable SLI to use all monitors. unless I install my 680 for the other 3.) I use to play on 3 nvidia surround with all 3 in mw3 and bf3 on my 680gtx; had very little issues.

1. Is my card faulty or is it a driver issue?
2. If I should have to return my card to replace it for a new one or the 780ti. Which setup should be better. (taking into consideration that I have been told mars 760 sli would not scale correctly)


I have noticed on a lot of tests Mars 760 out performs 780ti is almost all games except bf4. (I do believe waiting for the titan black edition would be ridiculous it being over $1000 for one card.)

Could someone give me an honest opinion with facts?

For the black screen flashes, its really only during call of duty: Ghosts which I play after working all day for an hour or so. If I ALT+Tab it goes away for a few games then happens once. When I first used my card I played for 2-3 matches and my screen flashed black about every 30 seconds for 10 minutes until I tabbed in and out.


Thanks everyone!

My answer above was pretty long.

If you can't SWAP to a different card my advice is just return your current card and keep it. It's a nice card.

If for whatever reason you decide you must get a GTX780Ti, then THIS is the one I recommend ($730): http://pcpartpicker.com/part/evga-video-card-03gp42884kr

Another option is to get TWO of the EVGA GTX780 967MHz models. They are $490 (USD) each which comes to $980. Expensive sure, but a much better value than two 780Ti's IMO ($500 more) which might be overkill anyway but that's your call looking at SLI benchmarks for the games you wish to play (at the resolution of a triple monitor setup which I'm guessing is 5860x1080.

Hi,
1) It sounds like a faulty card.

2) A GTX780Ti is more than enough for a SINGLE monitor.

3) You SHOULD be able to run three monitors as a "single" high-res screen.

4) You do NOT want to run FOUR monitors anyway because it puts the GAP between monitors right in the middle. However you should be able to add the fourth as extended if you can use all of the video cards outputs.

5) *Can you even SWAP for a different card?

6) I generally prefer the best SINGLE graphics card. Single GPU setups tend to game SMOOTHER (less stutter) though some modern games have good SLI profiles.

7) How much VRAM does the MARS760 have. If it has a total of 4GB, then that is 2GB per GPU. The GTX780Ti has 3GB. In SLI the VRAM is the same on both cards so 4GB on a dual-GPU card is still just 2GB.

You'll want to invest in 3GB per GPU with a triple monitor setup.

Summary:
What you do depends mainly on if you can even return the card or decide to sell the returned one. My advice is get a quality GTX780Ti (read reviews carefully) possibly an Asus model. It's more than enough for a single monitor, but again you should be able to handle THREE anyway so not sure what you've done wrong there.

For gaming on TRIPLE monitors (not four) you'll likely want a 2xGTX780Ti setup depending on the game.

I don't always have 3 monitors going at one time. I could easily with a 30 day money back through new egg. I literally installed it Wednesday. I could just mail it back and not worry about it. and then wait for a credit and order the 780ti.

I did notice more stutter and It might be faulty card. But I can run a few other games without issue. I booted up the old WOW, assassin's creed, and bf3, mw2 with no black flashes and such. Maybe its the game or the amount of stress on the card causing the fault to take place.

I FurMarked my card and was running 75-80 fps but the card got loud as heck and 80c one gpu and 71 the other. but it was stable with no issues.

The super clocked evga 780ti is a beast...I would only choose the mars for a small form factor build that I never planned on going ski with...also the 780 is enough by far for a single 1080 monitor.the to is going to be the difference of 100fps to 90fps on the normal 780.
