Calling all multi-GPU owners

crossfired 5750's for over a year in the beginning the support on drivers was bad for the last 8 months ive had no issues at all with them and most games it was scaling around 80-90 percent which is great. But I dont change games often so wouldnt have experienced new release issues if any for the newer games.

Ran crossfired 4870's for a year, and have been running crossfired 5870's for the past year. No huge problems at all. It's a little annoying having to wait a week or so sometimes for latest games to work properly on a dual card setup, but that's been the only issue for me.

I've been lucky in that both motherboards I've run 2 cards on left a slot gap between the cards, so both cards managed to get a decent amount of ventilation. Not sure how much of an impact this had on temperature, noise and stability but it must've helped.

Currently hoping to go to a 7970 (purely for the better Eyefinity performance) but would have no issue crossfiring in future and would do it without a second thought.
 
Had both SLI and now CrossFire, would do it again with either in the future.

The biggest problem is if you are looking for day 1 performance, look elsewhere, single cards need a new driver most of the time never mind 2 of them.

Next problem is you need a decent cpu for the scaling to work properly, [email protected] was choking the life out of my 6950>70's, most of the time only getting about 50-60% scaling, [email protected], 80% and upwards(game dependant) in the same games.

As stated above, if there is a weakness in your setup, or indeed PEBCAK or/and your inability to keep your PC in order, dual cards will find it.
 
Had 9800GTX+ in SLI a while back but upgraded to a GTX480 (this was early last year). Had no real issues running SLI it was just that the cards were showing their age more than anything.

Have had both single and multigpu setups of both nvidia and ati over the years. The only thing I didn't like was the noise as the PSU winds up more in addition to the 2nd gpu.

That said I'd have 2 5850s if I could fit them in my case.
 
Crossfire 6870's here and love it, never had any problems that are banged on about and thrown around here. run most games @ 180p on high settings. thats in BF3, Skyrim, and Saints Row at the moment.

2011 was a rough year for crossfire I would say, quite a few releases took a good few weeks to get the kinks ironed out, but all in all was it worth it? Yes.

This, as long as you've got abit of "tinkering time" then I would say it's worth it.

Quick question for you 5850 CF users, I've also got a CF setup and been playing a lot of Battlefield 3 recently and been having "not great performance"

Running 1080p with "custom settings" most things on high and getting between 40-60fps most of the time.

One of the things I noticed yesterday was that my first GPU was like 60-70% whilst my second was 100% permanently... CPu was like 60-70.

Anyway ever noticed this with crossfire setups, that the second card is working more than the first? its like the performance issues i'm having is because the second card is being overloaded or something?
 
Useful replies guys thank you.

i7 920 @ 3.5ghz
6gb ddr3

1080p gaming

Considering those specs, how well will a couple of 6850's fit in? In terms of scaling, power consumption etc. Games I play are GTA4, MW2, NFS The Run & I'd be tempted to install Crysis just to see how it runs.
 
I ran the following:

280 x 2
8800 x 2
5970 x 2
6970 x 2
295 (dual GPU)
6990 (dual GPU)


Issues: All have screen tearing to some extent and microstutter to some extent. This cannot really be helped by anything i've tried as it is purely random.

When a new game comes out, sometimes it might be a week or a month for support for multi-GPU setup support.

Power and Heat are the biggest issues. If you can live with louder fans and a warmer room, then go for it. FPS is always flawlessly high.
