GTX 780 SLI question

Hey guys

Just a quick question regarding GTX 780.
My buddy just got a GTX 780 about two months ago.
He wants to know if he can get a GTX 780 ti and "SLI" it with the regular GTX 780.

My response was that, you can but will under perform the 780 ti. Assuming that SLI will force the 780 ti to match his regular 780.
My buddy games with Qnix at 1440p resolution. He was telling me his regular 780 was struggling to have all the setting in BF4 on ultra with respectable frame rates.

Is it worth getting a 780 ti or another regular 780 and SLI it?

He wanted the Titan. But from the side by side. 780 ti is faster over all.
 
Ohhhh. What do think its better way? For him to get another gtx780 or sell his current 780 and pick up a new 780 ti? I already advise him against the Titan. But the memory is tempting. Does the memory make a difference ion 780 ti? I noticed that even at 3gb, its a faster ram.

Basically, yea. The Ti has 2880 cores, the 780 has 2304. They may be the same architecture, but they're still entirely different cards.

I suspect it would be possible for Nvidia to code drivers that would make such a thing possible, but it's not really in their interest to do so. :(

If your buddy is set on SLI, he'll need to do up another 780. No reason to be bummed about that, though. 780s in SLI will most assuredly nuke a single 780Ti's performance in anything that supports SLI reasonably well. :D

Two 780's. Assuming the rest of his system is set up for it.

oshia makes a valid point on the system. Reference 780s in SLI are (relatively speaking) pretty low power consumption but, he's going to want to make sure he's got the juice to support that configuration.

Its because it would be pointless to do that. Might as well just 780 sli them
 
Yea i told him that. Since the price of regular 780 dropped considerable its more bang for you buck.

On a unrelated question from my buddy issue...
I just got AOC 29 inch ultrawide monitor from newegg (got it at $380 sale). I have 580 classified ultra running on my rig. I noticed my graphics quality dropping since i am gaming at higher then 1080p resolution. What will be good card? I am thinking 780 ti for my situation.

Wait and see what the non-reference R9-290x cards have to offer.

You are gaming at 1080p unless AOC produced a new 29". I know what you mean though. Upgrade 780 ti if you want to burn some cash, unless you can wait it out for a few months for the price to hopefully drop.

No his rig is fairly new... its only 2 month old (I think). He has i7 Haswell CPU and Z87 Mobo from Gigabyte with 1200Watt PSU, I think he has 16 gb of DDR3 Memory

The GTX 780 Ti has more CUDA cores, faster memory clocks, and different memory modules. The Ti cards also use different firmware than the older 780 cards. Because they'll show up as different cards you won't be able to SLI them.
