    Hi all,

    I have 2 PC one for MOvies and Full HD games and one stronger better PC that plays games at 2500x1600. one is all ASUS (ROG) the other MSI

    the MSI one had one GTX 760 and i was not satisfied with its performance while the other one had an ASUS gtx 780 DC II which could handle everything i threw at it.

    I decided to get another MSI gtx 760 in SLI since most reviews i read supported 2 GTX 760 in SLI beat a GTX 780.

    yesterday i made the switch I put the GTX 780 in the FULL HD computer and the results were amazing.
    unfortunately when i tried the GTX 760 the results were exactly the same as with one GTX 780.

    for example

    UNIGINE 4.0 EXTREME PRESET 2500x1600
    GTX 760 sli 34.3 FPS
    GTX 780 (Oced) 36.8


    what am i doing wrong???

    Going to need the rest of your system specifications. Also, at that resolution the 760's are going to struggle more with less vram.

    so i should put the GTX 780 as the main card at 2500 x1600? the systems are the same only difference is brand. both have z87 motherboards i7 4770T and 16 gb of ram.

    Hi, i just checked, 4770T clock is only 2,5 GHZ. I think its too low and what you observe is cpu bottleneck. I dont know if 4770t overlocks or have turbo. But if there is any option, just raise the clock 3.5-4.0 and you should see 760 in the lead.
    now you dont have enough cpu power to feed 2 cards, thats why they are slower than one 780.

    edit. 4770T has a turbo clock of 3.7 GHZ, if its possible set turbo on all cores 3.7Ghz. And you should see the difference.

    I would leave the 780 in your gaming machine because a single card solution is always more stable and reliable than an SLI solution when it comes to games. As far as 2 760's being "better", it's really a toss up. You're looking at two cards with less vram being shared between the both of them (Assuming you have the 2GB version), and less memory bandwidth. Stack that together with higher heat output from the two being close together and in my opinion, you don't really have a more viable solution than just your 780. While you could call the 760 SLI'd cards "better", you're only looking at a +10-15 fps increase with less overall stability. Not to mention not all games support SLI very well, and a lot of the ones that do are not ideally optimized, so in some cases having SLI can actually hurt more than it helps.

    If it were me, I would have the 780 in my gaming machine without question.

    2 GTX 760 2GB SLI smokes even a 6GB Titan Black! I know because I've benched my 2 GTX 760 2GB against 1 and the difference was anywhere from 30% to 60% faster.

    Your problem is the test. Unigine is the the only thing that showed my 780 beating my old 660 Ti sli setup. Try a game. In Crysis 3 I lost 9 FPS going to a 780.
