Hi all - I am currently running one Gigabyte 1070 G1 gaming that I bought shortly after their launch about two years ago. I am upgrading to a better motherboard and chip soon(x399 setup as opposed to my current z170 setup). I do not game much but would like to upgrade my graphics a little during this upgrade. Currently, I can pick up a new 1070 at a great price. My questions:

Would you recommend I upgrade to the twin 1070s or just save and buy the new card?

I got my current G1 gaming card over two years ago - would a similar model work well with this or does it have to be 100% the same card? (It will still be the G1 gaming from gigabytes, might just be that it has received some upgrades over the past 2 years. . .

Many thanks,

for SLI it doesn't need to be the same card in regards to AIBP.

But it does need to be the same GPU (i.e. 1070 with 1070 or 1080 with 1080 not 1070 with 1080)

When running SLI, the weakest card determines the performance of the other, so let's say your G1 can overclock to 2050Mhz on the core and 6000Mhz on the memory (12000Mhz due to double density)

But the new 1070 can only overclock up to 1950Mhz on the core and just for the sake of it let's say the same speeds for the memory.

Because the new 1070 runs slower, so will the other card so that their speeds are matched when running in SLI.

As for saving up for 20 series cards, don't bother unless you really want to try taking advantage of RTX in literally the 1 or 2 games that...

As for saving up for 20 series cards, don't bother unless you really want to try taking advantage of RTX in literally the 1 or 2 games that support it and at the cost of FPS. When it comes to standard rendering techniques, the 20 series is not any better than the 10 series with the exception being the 2080ti (which is really the titan of the 20 series not to be likened to how the 1080ti is a TI version of a 1080 while there's still a Titan that was made) and even then, the performance increase of the 2080ti is not worth the price.

If you have an appropriate PSU and motherboard spacing for running dual 1070's then sure, you can do that. not very many games scale well with SLI these days though since SLI is kind of thing of the past and wasn't really supported well on pascal.

If it were me, I'd just bide my time and save up a little bit and just upgrade to a 1080ti instead and call it a day.
