Any card that is the same height of your current card will sli perfectly with any rigid sli bridge. Any cards that are taller will need to be sli'd with ribbon style sli bridges.

Yeah what he said the difference would be location of the sli bridge. I am on the same boat with you right now. I have 3930k system it is still working great for me beside 1 stick of ram just die on me few months ago

No problem. As long as it's a 1080 ti you're good. =)

 
Thanks, guys, for those responses.
 
So, I'll try to finish off this thread by organizing my thoughts a little bit, as well as by giving a little more detail on my upgrade plans.
 
Regarding the upgrade, for the first time I am going all-in with AMD (well, nearly all-in): X399 motherboard w/1920X Threadripper.  Primarily, this was done to maximize the PCIe<->CPU bandwidth (64 lanes), so that nothing of consequence would have to go through the chipset.  And, again, this upgrade is being undertaken because my current 8-year-old X58 + Core i7-960 is struggling to keep up with my new wireless VR setup (CPU usage goes through the roof).  I don't think that the GTX-1080 Ti is, in any way, a bottleneck to the VR goal, so that's why I'm not considering it in the upgrade (apart from the possibility of adding another).
 
So, given that, I'm now trying to choose between the following GPU options (the same sort of dumb question that folks like me, who only really pay attention to the progress of PC performance during those times when they're considering an upgrade, ask):

1. Keep the single GTX-1080 Ti that I have until it can't keep up (probably foregoing high-quality 4K), and then upgrade to whatever is current at that time.  For all I know this could be all I'll need for many years to come, especially if I don't make the move to 4K (obviously, ray-tracing will eventually take us to new heights, regardless of resolution, but how long will it take?)
2. Add a second SLI-ed GTX-1080 Ti by taking advantage of the current market in used GPUs.  This would probably enable the 4K option (?) and extend the interval before a generational or technological change would be required.  However, is there a risk that raster-based GPUs will be completely superseded within the next 5 years?  This option will probably cost somewhere in the neighborhood of $500-$600 (GPU + waterblock).
3. Move to RTX now, and drop $1200-$1500 on the latest and greatest (I would probably go with an integrated waterblock).

 
I'm not averse to spending money on something, when the return (in terms of system longevity) is going to be high.
 
Any thoughts?
 
Thanks, again, guys.  The main question about compatibility appears to have been answered.
 
Cheers,

I would go with single 1080TI for now. It is easy to get sec one if you think it needed right. I would not jump on the 2080ti at all. I find it not a significant upgrade over the 1080ti. Technology change all the time compute get faster everyday. The net gen Ryzen coming out in couple months too. Save the cash for future use
