I currently have two 760 2gb and they arent that great (playing on max settings). I am looking to upgrade and I'm not sure which setup would be better for how much money I would be spending. I'm either going to go with two 770's(4gb) or a single 780ti?

More about : gtx 770 4gb single 780ti

If you ever plan on adding a second 780 Ti, I would go for a single 780 Ti currently; given that your PSU will support it.

But if you don't ever plan on using two 780 Tis, I would go with SLI 770s as they should out perform a single 780 Ti.

Well, the two 770s would be stronger than the single 780 Ti, and would cost 'almost' the same.

What's your display's resolution?

Going with a single GTX 780 Ti gives you a better upgrade path later on, two GTX 770's will give you better performance though but will cost almost $100 more. Personally I like to get a single high end card rather than 2 mid-high end cards. I'd go with the GTX 780 Ti or rather i did go with the gtx 780 ti.

2 770's would be stronger than 1 780ti but remember not all games support sli.

SLI will also use a good amount more power (=more $ over time) as well as produce more heat. I assume you have at least decent airflow in your case though. What resolution do you play at?

If I got the 780ti and then later bought a second one, would a 750 watt PSU support the two of them?

I currently play at 1080p but plan on upgrading to 1440p later.

Yes, as long as you don't have some major overclocking on your cpu/gpus a good quality 750w psu should be plenty for sli GTX 780 ti's.

No 750w is not enough got gtx 780ti sli. my system can get up to use over 500w when playing high end games and the gtx 780 uses 250w so 2 of them would not be very good with only 750w

No 750w is not enough got gtx 780ti sli


Umm but it is... The power draw from a gtx 780 Ti is a max of 250w, most test will show a power draw FROM the wall around 450-500w for total system meaning max from wall would be around 750w with 2 GTX 780 TI's... say you have an 80% efficiency PSU... 750w from the wall means your PSU is supplying your computer with 750x.8 or 600w... Meaning he would still have an overhead of 150w with full system at 100% load.

Im not sure that you calculated that right so if i was the guy, i would be safe and get a 850w

Really? you are not sure i calculated that right? What do you think I did wrong exactly? lol... You don't know what you are talking about so you recommend more than is needed... Don't force him to upgrade when he has no need of one.

how do you know what you are talking about? you just look plug a watt calculator into the wall and see how much it pulls. You dont know how much which game pulls more out of what card so you can't really say that it only uses 450w to 500w. What if there comes a game out in 2 months that really pushes the 780ti in sli to the limit and it really needs to run on full load and the 750w not delivers enough power to the card. What do you think will happend? Im pretty sure you havent tested it correctly mr ''i know it all and everybody is wrong besides me''

These values are taken from benchmarks that push the cards far harder than any games will... I'm not saying everyone is wrong and I am right... I'm saying if you are going to call someone out and say what they said was wrong you should really back it with some kind of proof.. not just you have a feeling it won't work.

He asked a question and I answered him and the you came back and said "no it isn't" with nothing to back it.

I would still get a bigger psu because you get more bang for the buck, because in 1-2 years you might have to replace your gpu and you want to sli 2 gpu's that pulls over 250w and then you can actually do it. Psu's will last a long time and if you can use the psu you use now, in 2 year then you actually saved money instead of having to go out and buy a new one

What?!?! He already has the 750w PSU how would him buying a new one (that he in no way needs) save him money in the long run?
here is a review showing SLI gtx 780 ti's pulling a full system load of 652W from the wall ( so PSU is supplying about 530w to the computer )

You have got to be kidding me... Lets look at this for a second... He has a complete computer and he is running two gtx 760s on this computer. He is upgrading his video cards, asks if 750w is enough to handle the new cards... Do you really honestly think he is talking about some PSU other than the one in his current system?

you are so stupid. Don't you think everybody wants to save money? I imagine him seeing a 750w psu and thought like ''hey! i can save money by buying this instead of 850w and it might still work'' and it would be stupid otherwise just going and buying a bigger psu for no reason. Then he went on toms hardware and asked for advices. You know nothing about this guy. you don't know if he has or does not have a 750w psu. You do not know if gtx 780ti sli runs at maximum 450w-500w. you dont know anything about this topic.

Umm, I a bit confused with your math. Can you explain it a little bit further please?

From the link you gave the "Load Power Consumption - Crysis 3" for sli gtx 780 ti is 556W and FurMark test shows it at 652W. Lets say that 652W is the maximum peak wattage the system would pull, a 80% 750W PSU would offer 600W at the least. Now I realize that current games probably wont force it to pull that much wattage but who knows if maybe in the future games might do that.

Sorry, English is not my first language.

A 750 w 80% efficency Psu can pull just over 900 w from the wall to supply the computer with 750 w of power. Not the other way around.

That all you have? just call bullshit and say i disrespected you? ( even though you are the one calling me names ) Then ignore all proof i have given showing SLI GTX 780 Ti power consumption? Avoiding giving any proof... i guess you are admitting you are wrong...

LOL. ok this thread gave me a good laugh.

It's a pretty safe assumption that if he has a full system already with sli 760, looking to upgrade and is asking if 750W is enough that he is talking about his current PSU. No wild leaps there =). Thanks for the informative links Derza but you should not entertain such stupidity from other people for so long :p 

evgalover, for the sake of all other users who enjoy this forum please don't argue with conviction but no fact, it's just foolish and it misguides people. Provide something tangible at least =)
