Crossbridge 2 7950's or just get new r9 280?

post #1 of 20
Thread Starter 
The title says it all really. I am thinking of upgrading but money is an issue. Buying another 7950 and bridging would be cheaper than buying a new r9 280 but what would be the difference in performance?

Cheers

A 280X and 7950 are very close clock-for-clock, the 280 and 7950 are actually identical.

What card do you have now, a 7950,7970, 280, or 280X?

Dual 7950s (Especially if they are overclocked) will be nearing 2 times the performance of a single 280X. Now, as the consensus around here is to go for the single fastest gpu you can afford, buying a 280x over a 7950 is almost more of a side-grade than an upgrade. I say if you can find a 7950 for under 300 bucks, that is the way to go.

Indeed, a 280x isn't even an upgrade, as it uses the same silicon as a 7970 (which is only a hair faster than a 7950). I was assuming you had a 280X but didn't want to pay for another.

The R9 280 is a 7950. The 280X is a 7970 Ghz. They are carry-overs from last generation that have been renamed to fit AMD's current name scheme. I'm not 100% sure, but I remember reading about how the 280 will Xfire with a 7950. I'd have to research it to be sure, but I do remember reading something about it.

I would buy whatever you can find for crossfire,hd 7950,7970,r9 280x/280 for a good price
post #9 of 20
performance difference from a single 280x to crossfire 7950's can be as high as 75% or more. The 7950 is not far behind the 7970/280x maybe 16% slower on average...

Neither, the 7950's were going for $200 and lower on sales for most of last year (pre mining craze) so from my view both are bad values. Wait it out for next set of cards and whether it's a 870/8950 upgrade then. For 1080 a 7950 is still very capable so my suggestion is neither, but if you really must choose the 7950 is the only choice and there a few in the FS section ranging from 250-300, though personally I would probably sell it before value further plummets and spend an extra $150ish on a used GTX 780. Good luck with your decision though. thumb.gif
