GTX 780Ti SLI as second GPU set for the larfs?

[WFMG]

Hello! I've seen an ad for two used 780Tis fairly close by, for a, what I think is a decent price. The equivalent of $225 for the pair, including the bridge. Now, I'm happy with my R9 390 and its 8 gigs of VRAM, and I run a 4K monitor, but if I were to get these cards and a better PSU (850w for all three?), would the 780Tis perform better at 1080p and 1440p than the single 390? Would you think it worth it? Is it better to just save up for a new, better GPU, or should I dick around with this for a while? The value of the GPUs can only go down. What wattage would you think I'd need for a decently efficient PSU?

[WoodenMarker]

Yes, they would perform better. If you have the money to blow, then go ahead. Otherwise, going to 780 Ti's would be mean more power consumption, heat, noise, and sli problems. 

A good 750w would be fine, If you're doing bios unlocking and pushing for higher oc's, then look at an 850w.

grab the 780ti if you want higher performance but would gain power usage and heat. I would pull the r8 390 out.

Don't buy the 780ti sli. Sli doesn't work in 40% of the games, and you may sometimes experience stuttering on games.

true but for 225$ that is a steel. even if games will only work with one http://gpu.userbenchmark.com/Compare/Nvidia-GTX-780-Ti-vs-AMD-R9-390/2165vs3481

225$ is a good price; But the main problem is that he/she will experience extreme stuttering in games.

then disable SLI for that game. 

[Hunter259]

I'd buy them just to resell them on Ebay or Reddit tbh. That 3GB of Vram is going to kill you.

That makes no sense at all.

the card by it self is faster so if a game is studding with SLI turn it off in the control panel. you can select what games you want to use sli or not

Ehhh. They are more equal at 1080p and the 390 is better as the resolution scales.

 that is a single card for games that work with sli it isn't a fair fight

I understand that but SLI is extremely finicky and the extremely low Vram is going to cause problems to actually use the power of those chips. I'd still buy them but only to sell them and the 390 to buy like a 1080.

A 1080 is about 7000 SEK. I'd get perhaps, at best, 3000 SEK for the 780Tis, after a decent wait. Then, maybe 2000 SEK for the 390, which is even further ahead now, with ReLive. So I'd still have to spend extra just to get a 1080, which won't last me that long with my 4K monitor. I don't know. It just looks like such a low price to me that it'd be pretty cool to have these cards that were so amazing not long ago. It's just that I don't have a high income, as a minor without a job, and I'm saving up for an upgrade. (Though I did blow 4500 SEK on a gaming laptop, but I don't really regret that. I'll be glad I have it when we have the next school LAN party, or when I need to do stuff remotely.)

 

Honestly, though, my R9 390 handles 4K quite well. The 3GB thing is what bothers me the most. Both 1080p and 1440p don't look nice on my 4K monitor, and I have no interest on gaming on my secondary (1080p) monitor. So I could spend that money on the 780Tis, and just dick around with it, since a card that will max out 4K without trouble with contemporary games will probably not come this year, but with Volta, or whatever the 2018 nVidia ones are called, so I'd be able to afford them, anyhow. I don't really have a reason to buy the 780Tis, but I could have them for a while, benchmark them, and flip them, but I'd just get attached to them.

 

What would it take to power all three GPUs? I know only two would be used at a time, but they'd all be connected, and even the unused one(s) would be sipping some power at idle. Currently, I only have a 650w PSU. One of those hated ones. The Fractal Design Integra M.

All that matters is that it works in the games that OP plays IF he/she/it decides to go that route.

Hey, I recognise you.

 

Anyway, well, I saw a video of someone with two of these maxing out GTA V at DCI 4K (4096x2160) with two of these, and I'm wondering if it's legit, as the game saw it as 6 gigs of VRAM, not 3.

GTA V is just silly when it comes to multiple GPUs. If you had 3 Titans, it would see 36GB VRAM, even though that's not how it works. 

 

It is legit. It's just the memory usage allocation is a bit off. It used to say 4GB when i had two 2GB 660s.

So it gets that performance at max settings, even with that little amount of VRAM? Honestly, 2000 SEK plus shipping isn't that much to me, but I'd need a much better PSU, as well. That's another 1000 SEK at the least. Maybe 1500. A fair chunk of money, and I don't quite have that ATM. I guess I could flip the cards, but I could suffer bad luck with that.

 

I've e-mailed the seller, saying I'm only interested in both, asking for a picture of both (since the only picture is a picture of one of them), asking about 4K, and, if the seller has played at 4K, how it runs.

 

If it gets this close to a 1080 for this price (the price of one used 390 or less than a new 480), then it's amazing in price to performance, but I don't know if I'd be satisfied with the performance.

 

I'd still keep the 390.

I wouldn't really bother introducing the 780Ti's to your current rig. Drivers might be finicky with each other and it's just easier to save for something better than the 390 if you decide to upgrade down the road. 

 

Seems like an absolute steal but just doesn't really seem worth the effort unless you're really stuck.

Yeah, I don't know. I don't need it, but god damn! I'd like a card that does 4K well enough that it makes sense for me to upgrade from my 390, which I've only had for about 6 months. I want one where 4K doesn't seem so crippling, and it's more like 1080p and 1440p feel low res and easy to run. With some games, this is the case with my 390, but a lot of them really don't like to let me raise my settings much at 4K. I also really want to record at 4K.

 

I also want other things, like maybe some music production stuff.

 

Either way, I guess I could flip it, even with shipping, but goddamn it, I don't think it's a good idea, even though I really, really want to.

[jjohnthedon1]

Buy them 

just one is darn close too ur 390 on performance so 2 would be double the raw performance ?

SLI is in no way "extremely finicky" and the VRAM isn't really gonna be an issue. The 780Tis are a good choice for him, more power for the high resolution gaming he does, the games that don't support SLI the performance of one 780Ti is almost on par with a single 390 so two of them in SLI enabled games will be much more powerful. He won't notice any performance loss in non sli games and he'll see a big jump in games that do support it.

vram's going to be your main issue when it comes to 4K with the 780 Ti SLI. You're better off getting another 390. It'll be absolutely fine for 1080p, but at the same time so will the single 390.

[Mick Naughty]

Id go 780's. AS they are very similar to my titan blacks and I love the cards. Single 1080, triple 1080 or 1440. Best card Ive ever owned.
Zero issues with sli. It more of a misconception then an issue if people complain about it.
