You have a fantastic monitor. I know because I have it as well. In some titles, you will see a benefit from SLI. Good scaling will be about 30% improvement, giving you around a 20fps bump. But that is when scaling is good and when SLI works. More often than not, SLI will give you zero performance gains or hurt performance. Here is a really good read on SLI. It is dated 2014, but it is updated regularly and will explain everything.

As far as your system is concerned, the 4790 should not have any issues supporting SLI. I don't know what board you have, but most midrange boards that support the...

good luck finding cards at a decent price - currently not much in stock other than +300 over MSRP. you can find deals but you have to be vigilant. use a site like nowinstock.net and be ready to pull the trigger when something becomes available.

Honestly, I wouldn't buy the second card. You'll probably get very little bang for the buck if you go with SLI

EDIT: Since you've got that Acer Predator 34, and it has GSync, the adaptive refresh will probably be what gives you a smooth experience, instead of trying to constantly stay at 100Hz refresh. My only experience with anything similar is with AMD FreeSync combined with the Chill feature (and at a notably lower refresh rate).

I'd say try it all out with a single card, see how you like it. Worst case, you can always go for the second card in the future.

true sucks i have to replace ram/mobo just to buy a high end cpu but hey ill just try it.. if i upgrade to ddr4 ram/new mobo/8700k cpu i might just get what i want in my fps who knows. might not need to buy another gpu after we will see.

Many times it is the CPU holding back performance, but it is often from a single setting or 2. The same goes for GPU settings. Often times a setting which might make a 1-5% differences in visual quality can make a huge difference in GPU or CPU usage. Don't get married to "maxed out". It is not worth it much of the time.

If you gonna do SLI, the founder's edition cards are better suited because they will push the air out of the case and not heat the other cards up.

You could also just add a hybrid cooler to your current 1080ti. My 1080ti's have this hybrid cooler and my temps never go above 50C and they can overclock without hitting the thermal wall.
