Dual r9 390's vs gtx 980

[Lekingmoonya]

If I X-Fire 2 AMD R9 390 GPU's, will I get the same performance as a gtx 980? I am going to buy the 390 so in the future I was wondering If I should X-fire?

Yes, 2 390 should be significantly better than 980. You will also have to deal with incompatibly issues, power cosumption, heat output. With that being, gtx 980 is a poor buy performance per dollar wise. Gtx 970 is good card at that price point as it should outperform 390 when overclocked and will waste significantly less power. 390 does have 4.5 gb of vram more than gtx 970.

Dual 390s will destroy a single 980 in the vast majority of games.

It will perform much better in the games that support crossfire well. However that list of games actually rather poor.

 

[Azn Cracker]

Yea performance will be much better.

Crossfire scales pretty well on supported games, but drivers come out several weeks after initial release and usually only the big titles get good support.

Also you will be consuming 3x the power of 1 980.

recently the r9 290x have been going for $260 which make it a much better buy than a 390

Yeah the R9 390 8GB isn't really better than the 290X 4GB. The 8GB RAM number on the R9 390 is BS in my opinion.

However I can't see R9 290X's going for less than 310 dollars?

I dont think its BS. For a single card having 8gb of ram is useless very few games will go over 4gb of vram and if you did you probably wouldn't have the gpu horsepower to push it, however in crossfire it could be useful at higher resolutions there are a lot of games that will push past 4gb of VRAM at 1440p or beyond and in those games I bet it would be nice to have 8gb running through a 512bit bus especially since games seem to be using more and more VRAM.

I cant find a decent 290x that cheap either.

It was on newegg yesterday after a $30 rebate I checked again and the prices went back up. You could have also combined that with the $10 Amex promo to get it for $240.

In addition there is a $25 off $200 coupon, but that had to be applied through the phone if you are lucky.

So you had the potential of getting it for $215? I didn't jump on the deal because I already have a r9 290, but man that was a crazy good deal.

If it was 512 bit on Nvidia's Maxwell architecture I would believe it could. However on AMD's GCN I'm not sure. I don't think so.

But I do not believe in graphics cards, when they are originally sold for half the VRAM (in this case 4GB), they are made to support that amount of VRAM and not higher. This is just me and the research I've made I guess.

 

[Lekingmoonya]

So.... What should I buy..?

 

[RCFProd]

Two R9 390's will draw a lot of power, and crossfire won't work properly in many modern games. I wouldn't really recommend it.

For Nvidia, SLI is ok but still far from perfect in a lot of games. So if you're planning to play with 2 GPU's, I'd say go Nvidia.

For now, with one GPU, EITHER the GTX 970 or R9 390 will be fine.

For the GTX 970 you're ok right now with a 500w power supply whilst 600w or higher is recommended for the R9 390.

 

[Lekingmoonya]

Is the gtx 980 worth the price? If not, is there an AMD equivalent?

 

[RCFProd]

The AMD R9 390X is about as good as the GTX 980.

GTX 980 is not quite worth the price imo.

R9 390X price however seems good.

In this video https://www.youtube.com/watch?v=lYQT8udtuWM The 980 has at least 10 fps more than the 390X. I don't want to overclock because that will void my warranty but... Is there any AMD card that ties with the 980?

 

[Azn Cracker]

You should get a single 980ti, which would cost the same as 2 390's.

If you overclock it it should get close to the same performance as the 2 cards without the crossfire support problem + consuming about half the power.

In a lot of benchmarks you can actually see the R9 390X performs just like the GTX 980, in that video. Official benchmarks apps also show really similar performance.

But It's true that GTX 980 Ti single is best compared to 390X CF for example.

You should get even better performance than a NVIDIA GTX 980!
