Crossfire Radeon HD 6950 vs NVIDIA Geforce 670 is it worth?

post #1 of 17
Thread Starter 
I have a HD 6950 1 Gb with unlocked shaders. Is it worth to buy a 2nd video card and install crossfire? I was looking at a NVIDIA Geforce 670 but it's still very expensive?

Two 6950s would give you more raw GPU power however the 1GB of vram is incredibly limiting so it's definitely not worth doing. If you have the money go with a GTX 670 or Radeon 7950/7970.

You can only Crossfire cards that are from the same series and the same manufacturer (ie AMD, Nvidia)

So you can only Crosfire a 6950 with another 6950, and a 670 with another 670. Also the Crossfire equivalent for Nvidia is called SLi

OP was talking about crossfiring a 6950 WITH a 670, not debating if its worth it etc

I think he just phrased it wrong, the title says crossfire 6950 vs 670.

Thanks, the GF 670 is about 300-400€. Is this high end or medium class? I also play only in 1920x1080. What is exactly is limiting the 1 GB Ram? I also see that amd is better in number crunching... i.e. bitcoins? When I have 200-300€ maybe upgrade my cpu?

Most demanding, modern games require 1.2-1.5GB of vram at least to play comfortably at 1080p using high settings. As far as standards go, nowadays 1GB is the lowest you can get, all mid-high end cards will come with 2GB+.
