Crossfire or Single card upgrade?

post #1 of 20
Thread Starter 
I currently have a Radeon 6850, and I was wondering what would be the best option - sell it and buy a high end card (GTX 580 or something), or buy another 6850? What would be best bang for the buck? I've never done crossfire before, are there any major downsides vs one awesome single card?

Yes, there are downsides. Choppiness, screen tearing on some games. Some others just plain don't work. Also, your top card is almost guaranteed to overheat.

Go with a single card IMO

Dual cards=more heat, requires more power, micro-stuttering and screen tearing in some games= more hassle.

I agree with ronnin,
there are downsides of multi gpu setup,I'm a believer of single gpu setup.
Go for evga gtx570 classified(822mhz core clock),its much cheaper than a gtx580 yet its performence is better than a stock gtx580.

I have a CF setup. I don't recommend it. There is a lot of driver issues. If you do get a CF setup then I recommend you download RadeonPro (http://www.radeonpro.info/en-US/) it gives you more control over how CF works wit a specific game.

If anyone tells you "Yes! Go CF!", shove both cards down his or her throat... or up...

Get a single, better performing card for multiple reasons:
1) Less heat and power consumption
2) Less driver issues
3) No micro-stuttering, lack of CF support in a game, etc.
4) Allows room for CF/SLI setup in the future with the release of a newer generation since prices will most likely drop and the price/performance ratio would easily not warrant getting one of the next gen cards as opposed to the multi-card setup.
5) Did I mention less heat and driver issues?

i thought the latest 6xxx series cards are rather cf friendly, i could be wrong, i don't own a cf setup, but from what i've read in reviews, they're generally pretty good.

if money is not a problem, by all means get a 580 or 6970, 1 card is for sure less buggy. but in terms of best bang for the buck, cf your 6850 is the winner in my opinion.

EDIT: seems to be a bit of a conflict there, or not?

I went CF (HD 5770 & HD 5750). Quickly sold them and went for a single card.

Scaling is good but as others have said some games don't utilize it, you have to wait for new drivers for some new games, higher temps and your overclock will need to be dropped quite a bit.

In benchmarks my old setup beat a 6870 (my current card) but in games the 6870 ALWAYS wins, not to mention lower temps, higher OC, less power required.

If you can save a nice amount of money then go for it, but only if its quite a bit cheaper than selling your current card and upgrading.

You could also wait for the next-gen of graphics card, they shouldn't be long now...

AFR rendering doesn't actually boost _minimum_ framerates very much at all. Some will argue that they don't notice the low minimums, but if you don't notice low framerates, why do would you want to spend the extra money on dual cards in the first place?
