I currently own a 4992 (SC,blower), and 4995 (SC+,ACX,BP).  I want to add another one, I don't know which but will try to find the best deal.  Can I SLI these three and expect the same performance as say having all three cards "match?"  Although I suppose they do match, just different coolers.  Thanks for the help.
 
Oh also, I have Watercool Heatkiller blocks for them, so aesthetics is no matter, they will all look the same when installed.

    Yes, and the third will most likely be 4995 as well, it is by far the cheapest right now.

    Welcome to the Forums iamwill3292!
     
    You can SLI the 980 Ti's even if the part number does not match. The performance will match whatever the lowest performing model is. It is also important to match the same VRAM capacity but that will not matter with the 980 Ti's since they are all 6GB.
     
    You can read more on Nvidia's SLI FAQ here: http://www.geforce.com/hardware/technology/sli/faq

    It would help if you gave the FULL part numbers AND model names. GTX 950, 960, 970, 980, 980Ti, or Titan?

    I tried looking up those partial part numbers you provided, but EVGA's product page broke for me and I couldn't see more than the first few products. So, I am "???".

    For what it is worth, some cards cannot officially be SLI'ed together accross different part numbers due to SLI revision differences (GTX 970 models).

    Wouldn't recommend, unless you're okay with them both working on the lowest performance rate of the two.
