Here are my specs:
Intel I5 6600K (Stock Speed 3.5ghz)
ASUS Z170a
16 gbs of Memory (Kingston Fury Black)
GTX 980TI (Haven't started SLI yet)
750 Watt EVGA G2 PSU
Lots of fans with 30 watt fan controller (3x200mm, 2x140mm, 3x120mm).
Phanteks Air Cooler (Latest one, don't feel like looking it up).
Gigabyte WLAN Card
1xSSD, 1x7200HD, 1x5400HD

So here's my multiple questions that I have for this future upgraded build with another gtx 980ti and 1000 watt EVGA G2 PSU replacing 750watt, maybe extra 16gb of same ram in future.

1. How much will it affect the electricity bill? I live in the parent's house, so I don't really know, because they just generalize the electricity bill being same (too much; typical Asian family with the word "So Expensive")?

2. Would my 2160 joules surge protector from triplite able to keep up?

3. Would SLI bottleneck my cpu? If so, would overclocking change it, since its unlocked CPU.

4. I have 1080p monitor locked at 60hertz, Weird that I have beast of a machine with weak monitor right? Should I upgrade the monitor?

PS I live in Arizona.

1) the wattage of your psu does not directly impact your average pull from the wall. its how much it CAN supply to the computer, not how much its always supplying. if anything they tend to draw a little less as higher end models are usually more efficient. 80+ rating improvements and all. so you will really only be drawing more power with the new setup than you do now when you're putting both gpus under load.

2) um...idk the math off the top of my head, but im sure you can easily google a calculator.

3) honestly i think your cpu will be fine. you're not adding a ton more load to it with sli.

4) 980ti's are already overkill for a 1080p display, let alone in sli. but personally i would upgrade the gpu's now, then the monitor...

Drop the idea of SLI, keep the same power supply. Just upgrade the card and the screen.

If SLI scaled perfectly, I would recommend it, but it doesn't, so don't.

If you want to SLI, you'll most likely need a new power supply and to bump up the clocks a bit on that i5.

The joule rating of your surge protector, how many joules/msec can it handle?
