Never going back to CrossFire!

post #1 of 8
Thread Starter 
I've just upgraded from a 6850CFX setup to a single 7970. On paper, a pair of 6850's is very similar in specs to a single 7970. Benchmarks I've seen online confirm this. The 7970 should be slightly faster, but not a big difference either way.

I ran some benchmarks on each system before and after. Primarily Heaven and Dirt 3, both in single monitor and Eyefinity mode. I noticed immediately an improvement. Even when the 7970 is running down at 15fps, it looks smoother than the pair of 6850's running at 30 or 40 fps. I noticed this improvement instantly when running the Heaven benchmark in Eyefinity mode.

What I've learned today: Microstutter sucks! And I will not go back to a multi-gpu setup again, until some new hardware is released that eliminates that issue.

always best to go Nvidia in the high end because of superior driver support

ATI in the mid and lower sector all the way.

Well single GPU is always better than using 2 and linking them together. I think the idea behind Crossfire and SLI is that it's a literal bridge so you can run 2 cards until you upgrade both of them to something better. I still want to crossfire because I can't afford a 7970.

Yeah, I always knew a single card is better, if one exists that is better than whichever two you have linked. The main reason I upgraded now is because of my eyefinity setup. If I was still on one monitor, I would have kept my old cards for much longer.

I forgot to mention in my first post: Not only is the single card faster, and even when it's slower it still looks faster. But it's also using less power, and it is SIGNIFICANTLY more quiet. Huge plus on that.
Again, this is all obvious stuff, and everyone knows this. But it's all part of why it's better to have one top end card, than to have two mid end cards.

I downgraded from 6990/6970 trifire to a single 7970 and I was happy as the microstutter was killing it for me. Since switching to a PCIE 3 chip/mb, and adding a second 7970, I don't see any microstutter at all.

Yep no stutter here with 2x7970's thumb.gif

Honestly didn't have any stutter with my old tri-fire except in eyefinity... that was awful!

2x7950 here, can't see/notice any microstutter... Only bad thing is that i see some "lines" sometimes because i don't have v-sync on.

CF and SLI is high end Tech. If you are going to get 30 fps in CF or SLI get ready to ditch it. The stutter is insane @ low fps.
