Is 1070 SLI worth it? PSU Upgrade?

[J03Y098]

I managed to obtain a good deal (I think) on a couple of EVGA Geforce GTX 1070's for $300 and I'm trying to figure out if I should keep both or not. I'd normally just keep them but I used to have a single gtx 970 and so I had a EVGA 600W PSU and that was enough back then. The power supply can currently run the 1070's in sli but I know it is really pushing itself so I removed one card for now and I'm trying to figure out whether I should keep both cards and upgrade to possibly a 750W PSU, or just sell one of the 1070's instead for extra cash for myself (possibly to waste on food). If I do upgrade the PSU, what would y'all recommend I get? I was looking around and I'm thinking about the Corsair CX750M or Gigabyte G750H.

this unit has a pretty poor operating temperature, would definitely not do dual GPU

 

also $300 for dual 1070s? you can sell them for over $200 each probs and for that $420 ~ish you could almost afford a 2070 super.

 

If you want the dual GPU solution to work the Corsair CX650 would do it for you.

I probably wouldn't want to upgrade to something like a 2070 considering that I don't really play many heavy games or edit really high quality videos or stuff like that. The 1070 has worked well for my needs so I'm okay with it. Although I'm also not too sure I'd need a second 1070 either. I guess it's just in case I ever need to run something more and also because it looks good in my system.

Really depends on the games you play and how much effort you're willing to put into tinkering with SLI settings.

 

For average users, SLI really isn't worth it. For people who aren't bothered with spending time on system tweaks, and can accept SLI won't always work, no reason not to go with it. This is because many games either aren't SLI compatible from the get-go, or don't require SLI to run effectively. SLI compatibility can easily be expanded with driver tweaks, and older games can benefit from SLI if you super sample and/or use performance heavy ReShade mods, but this isn't the case for most users.
