post #1 of 11
Thread Starter 
Hi Guys.

i am about to pull the trigger on a single evga 780 gpu or 2 X evga 770's


what are your thoughts... and no i am not going to do AMD gpu's so keep that out of the picture please.

EDIT:

thanx for the help guys.


i have gone with the 770's, i ahve gone for the 04G-P4-3776-KR i will be ordering a second one from the local shops.


now to get an idea of the performance difference between the 670 and the 770 and sli 770, what tests do you want to see?


let me know and i will pot it up but this is while i have the 670.

i also got a spare evga 550ti i can bench and see how much of a difference it will be.

SLI 770s will provide you more performance, but the 780 gives you room to upgrade. I'd personally go with the 780 because if you don't game @ 120hz you will have to use v-sync in order to avoid screen tearing.

thing is if i go 780 i will not go SLI later down the road.

it will stay like that for the next 2 years unless they really come down in price. like at the 200 pound ark MAX

also my current monitor set-up is 2 x 24" 1080 monitors... so i have no tearing for the moment... i do know the 670 does struggle with the 2 monitors at this res.

Then the second monitor is negligible even for the 670. However, you most likely would experience screen tearing at 60hz with dual 770s. So, it really depends if you want to have all that performance and not be able to utilize it all. You might be better off just getting a single 770 now and if you feel the need for more power, sli then.

SLI 770s would be such a beast, go for it. Newer games like witcher 3 or cyberpunk 2077 will really benefit from a multi gpu setup. Or you could add another ftw for much less, my sli 670 ftws are still holding up really well, not going to bother with an upgrade til the 8xx series. I could buy a 780 ti sli setup tomorrow if I wanted, but the performance gains do not justify the money for me. In all honesty though, I would upgrade to intel, and I am not a fanboy at all. I started with a 965 be, went to a 1090t, and now a 4930k. The difference between the 1090t and 4930k is light and day, I get a lot more gpu usage in sli than I did with the 1090t, (around 20% more usage) so take that into consideration. Yes I know the 1090t is older than your 8350, but multi gpu setups play a lot nicer on intel, just some food for thought.

If you were upgrading "down the road", i would have said single 780, but you won't, so SLI 770 no doubt. thumb.gif

This is an example of the performance increase you should expect going with 770 SLI. Both setups are on air.

770 SLI @ 1384Mhz (core), 1978Mhz (mem)
Warning: Spoiler! (Click to show)

780 @ 1398Mhz (core), 1877Mhz (mem)
Warning: Spoiler! (Click to show)

26% performance increase, and it can go as high as 40% in some cases.

I always go with the just under flagship in sli ie x70 gpus in sli instead of an x80 gpu and get great performance, plus with overclocking I get the quality of two x80 gpus.
