How does Crossfire stack up against Sli in terms of support?

post #1 of 10
Thread Starter 
Hey guys.

I decided to Upgrade my Gpu's to the new generation of cards but i have a choice to go 7970 CFX or 670 SLi and i need to know which ones get better and quicker support.

The worst thing about running two cards is games not supporting them and having one just sit there so i need to know if the Red and Green team are on equal footing when it comes to updates for CF/SLi profiles.

Question is, are they?

SLI generally supports more games / is more optimized than CFX, although both are very good in most instances

What resolution you playing at? I have 2 x 7870 at 1080p so cant speak of sli but a lot of games don't even push my gpu`s to the limit. The games that do utilise it run very well, ie bf3, dirt showdown and the games I play. I suffer no microstutter and the new beta driver is great for me regards performance increase for free although I know some are reporting issues.

That figures then. Well as far as crossfire in my experience I have no issues whatsoever. Maybe list the games you play or hope to utilise crossfire in and check against the existing amd ccc cap profiles or user experiences with the same cards for a better idea. Same with nvidia

I am curious if AMD has a planetside 2 profile out yet??

NV is generally faster with profiles and have had the better anti micro stutter technology. I've heard CF has improved these last two Gens but during my 5870 days I chose my SLI 460's @900 core vs the CF 5870's solely because of profiles and performance generally being faster after game releases. So while the 5870 was still a stronger setup, even with the better scaling on the 460's, I had to wait longer for fixes and had to run with only one card until amd fixed things.

As you can see I only own one 7970 but from my prior experience I would give the slight edge to NV.

Be it sli or crossfire ,be prepared to rage a lot.ya it sound nice in theory but like anything modular for some reason those modular solution aren't as well supported as a non modular(probably why Intel and and never went from 1x p4 to 8xp4 via an adaptor etc

No they don't, my friend says the game is pretty much unplayable on his 7970 while I'm playing it quite happily on my 560 ti tongue.gif

A single 7970 should be fine for 1080p 120hz. A single one nets me excellent framerates at 6048x1200.
