I'm looking to get 2 x gtx 980ti. I've never had an sli rig before. What's your experience with sli is it worth it or a complete hassle. Do most games work ok or will I spend most time tweaking
I had 780ti's in SLI and for the most part it worked really well. On every major release I had SLI support either on day 1 or at least within a week of release. I have just ordered a single 980Ti and i'm more than open to the idea of getting another one down the line.
The only bad thing for me was really the heat 2 video cards knocked out into my room made gaming a little uncomfortable. I didn’t like the fact that every time I downloaded the latest drivers I had to re-enable SLI, that got a little annoying. The biggest issue I guess is you are totally reliant on the games being coded well for SLI. Obviously the disaster that is the latest Batman game is a good example, SLI is not supported at all, though the game is a mess regardless.
My advice would be to buy a single card if you think it's more than likey enough power to play the games you want to play at the settings you want, if/when it starts to stuggle you can either buy another card to go SLI or perhaps, by then the next flagship card will be out and could be a better option.
