So what will get highest fps in games? Gtx 770 tri sli or gtx 780 sli? How high psu do I need for 3 gtx 770's?

More about : gtx 770 gtx 780

Here's an article that goes into sclaing on the 700 series GPU's.

For the short read here's the conclusion:

The higher the resolution and the higher the quality settings, the more you will benefit from an SLI configuration. For example, the GTX 700 cards in SLI only scale an average of 55%, but in 5760x1080 with maximum settings the average is between 68% and 75%, depending on the card. A third card doesn't add as much as a second card does, and is typically more prone to compatibility issues than two cards.

A single GPU will always experience less synchronization problems such as micro-stuttering, for obvious reasons. That's why you really shouldn't spend money on two mid-range cards for an SLI configuration, and instead invest in one powerful high-end card with the same level of performance as two mid-range cards. In this case, better to have one GTX 780 than two GTX 760s. However, if you already own a mid-range card, adding a second one will of course boost performance.

While it's expensive, SLI is the most interesting for the high-end cards. It enables you to play with resolutions and settings that are simply impossible to achieve with a single GPU. The benchmark results were clear, a single GTX 780 often isn't enough for gaming in 5760x1080 with maximum settings and anti-aliasing. The second card is what makes the game playable. Considering the price of a GTX 780 or Titan, this is obviously not a hobby for the average gamer.

The chart on the previous page is very useful for finding out exactly what you need in order to be able to play a certain game in a certain resolution, and be guaranteed 60 fps. Should you buy a second mid-range card, or is it better to hold off and invest in that one high-end card?

Well, I'am not that good in english. So can you please explain me with easier words? Which will have highest fps in games? And btw, how high psu do I need for 3 gtx 770's? So how much better will my computer be with a third gtx 770 card? How many precent does it give you? Since the third isnt as powerful the second one.

3 770s would be 10%-20% stronger then 2 780s, that said many games don't support 3 gpus... and 3 gpus tend to have massive heat, power and micro stuttering problems. for pure build quality and play experience i'd get 2 780

What if you have 2 gtx 770's... Should I just sell them and buy 2 gtx 780's?

For three GTX 770's, you'll need 1000W or higher PSU. The 770's would be faster than two 780's in theory. But, I always add the possibility to buy another GTX 780, which would destroy the three 770's. If you need the best results right now, go with three 770's, if you want to have somehow more "future-proof" PC, go with two GTX 780, with the option to buy one or two more GTX 780's in the future.

i'm not sure the improvement is worth spending the cash frankly. if you've already got 2 770s i'd say you're pretty much set.

I agree with ingtar33. Now your new question sparks a new question. What is the reason for wanting more performance? What game(s) are not performing well enough, and what is the rest of your system?

Just answer this. Is Corsair 850w enough for 3 gtx 770?

No, it is not. But seriously, if you have 770 SLI now, what resolution are you playing at that makes it not work well enough? I'm trying to determine if you'll gain a benefit from another 770 or not. You may be limited by the 2gb of the cards, or be limited by your CPU or RAM. You may also have unrealistic expectations from a game or a system issue.

For most setups, 770 SLI is enough for near max settings with all games. I have 680 SLI and it is enough for 3D Vision, and if you are wanting better 3D Vision performance, 3-way SLI does not help it at all.

Okay. I didn't know. But heres it is

CM storm stryker
Corsair TX 850W PSU
Intel Core i5-4670K
MSI Z87-G45 Gaming, Socket-1150
Cooler Master Seidon 120M
Crucial DDR3 BallistiX Sport 16GB KIT
Gigabyte GeForce GTX 770 2GB PhysX CUDA
Gigabyte GeForce GTX 770 2GB PhysX CUDA
Kingston SSDNow V300 120GB
WD Desktop Blue 1TB SATA

1080p. But I was thinking to get the last card in about a half year and then I will have 1600p or 1440p

At 1080p, any of these upgrades are going to rarely help you. Most the time you'll limited by your monitors refresh rate and CPU. I would not upgrade. If you are having issues with a game, perhaps we can help you with that game. Perhaps you have something not working correctly.

EDIT: If you are planning to upgrade your monitor in half a year, then make your upgrade then. Most people consider 770 SLI overkill for 1080p, and more designed for 1600p. You may not have a reason to upgrade even then.

Make your upgrade first, then assess the situation. 770 SLI is considered high end for 1600p/1440p and in half a year, prices will change for the better, and we may have new cards to consider. Don't throw money at a problem until there is one. You'll save yourself a lot of poor choices.
