Can you SLI two different video cards?

[Germz]

Is this feasible or do the cards need to be same class aka two 680's. Even further, does manufacturer have to be the same as well (EVGA, ASUS, etc.)

Realistically it would make sense that they could be different classes as long as the GPU (in my instance GK104 GPU) architecture is the same the hardware would basically be bottlenecked to the slowest card.

Is this or is this not the case?

[Brianguy]

I don't know about these newer cards but I had a superclocked and regular 260 (diff manuf) paired and they ran at the slower cards clock. there was a chart somewhere to see what cards you could pair. have you tried nvidias website?

[Germz]

on a work computer that only allows IE7. not compatible with nvidia's website

you can SLI the same "number" series from different manufacturers. and yes, as Brian said if you have a 260 Overclocked paired with a standard 260 it will run both at the lower speed.

680 EVGA with a 680 ASUS will work.

SLI is really buggy and not really worth it. You often get micro-stutter, poor driver support with new games that just come out, etc.

With the power of single GPU cards these days, you are much better off just shelling out the cash for a single GPU card.

I played the SLI game for a couple generations ( GTX 8800, 9800 GX2, GTX 280s) and found I was much happier with single GPU cards.

I definitely agree. Most companies have a hard time optimizing SLI'ed cards.

I personally found it better just to get a higher end, newer released card that has the same capabilities of a SLI'ed lower end cards.

I have personally been using the Geforce GTX680 and I have a hard time finding stuff it can't handle.

well I have a 680 right now. But i don't feel like trashing it just to upgrade for another single :/

What are you running that is causing you to requires so much VRAM?

are you running some crazy high resolution while gaming that just doesn't feel smooth enough?

feel free to add another card, but a 680 is pretty beefy for anything at 1080p resolution these days.

Hell, I'm running 512 MB ATI 4870's from 2008 right now in my desktop, and with the exception of the DX11 eye candy, that's plenty of horsepower for most things I do at 1080p. Crossfiring them does improve things, but not by that much.

I was actually met with some resistance trying to run Metro Last Light on Max'ed out settings. I built my rig back in Aug 2012, it being almost a year (assuming the law of 6 months in technology is still valid) I figured it would be more than warranted to upgrade.

Here is my impression of SLI...


"UHHH!, get OUT." (very similar to the one night stand from Diceman routine)


I first made an SLI mode back in 1996ish or whenever the Monster 3D had their TWELVE MEG versions of the OPENGL cards that they came out with. I used it on Quake 2 and for LAN deathmatches. I had the cards in there for about 1 month before I decided it was time to upgrade to a single card and not worth the trouble with SLI.

SLI = benchmarking only. OR, if you are some rich snob that HAS to have the absolute fastest setup they can get, but in about another 6 or so months a new card will come out and blow any SLI you have away so why waste the money?

SLI on the downlow by getting two very affordable cards and making them be SLI if you MUST.

Else, believe me, SLI is NOT like pizza or sex. Pizza and sex are pretty good no matter what and bring a smile to my face, but SLI was rather sad and I REALLY had a lot better expectations. Heh, maybe SLI would have been cooler back in the 8088 days or the 386 days if you had two VLB cards, but now a days, can you tell the difference between 196FPS and 224FPS? How about the difference between 8quadbillion triangles and 8.1 quadbillion triangles?

Yeah exactly... Go do your SLI setup , then take it off and say that you been there done that and it has made you a single card player...

I am running on a $100 570 EVGA with 1.28GB of DDR5? Or whatever it is. Seems to work FINE for solitare...

I really can stilly, I really can....lol. you make a good point. and I think will take all of your guys (or gals...not sure) advice and just do a single gpu upgrade.

Planning on selling your 680? if so, how much we talkin?

you can't probably SEE the difference, but yeah i know what you're saying in that there is a noticeable difference in how the game runs.

hell, in older games like CoD4, you could only make certain jumps with 255 FPS where you couldn't with 125 FPS because the engine is running faster than intended.

this was the same in even older games like Quake3. Which is why punkbuster limits the FPS to 255 (i think) in many CoD type games.
