Can you SLI with different clock speeds? I didn't think you could -- it just makes both the lower of the two.

 

With two 970s anything below 4k is a bit wasted, unless you're actively going after 120-144 fps. Alternatively you could lay on the AA or DSR, I guess.

 

Nope. SLI has to run the same clocks. And OP, 4K is what you're looking for... with 2x 970s anything less (unless you have a whole lot of stuff going on) is wasted.

I will buy i second 970 tommorow it will be a Gigabyte G1 Gaiming cause i heard that this card is the best for overclocking  when i overclock those card my first 970 will obvisously perform different than my other one they will also booth overclock different like one 970 will reach 1500 mhz boost and the other one just 1450 mhz will the first card that is overclocked at 1500 mhz throttle down to the core clock of the other 970 or will they just seperate themselve and perform like they are clocked. 

 

My second question is: 

Should i go for 1440p with that type of sli setup i will overclock my cards booth as high as they can or should i go for 1080p, you should know that im playing very demanding games like Metro redux or Far cry 4 will they run above 60 fps with high or ultra setting and a little bit of Antialiasing ?

The projects never end in my line of work.

yes you can. i have done it.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

But it doesn't actually. It downclocks the higher card.

i have had different shader, core, and memory clocks before within SLI. i've done it.

VRAM usage is always synced though.
