6950 1gb vs 2gb for Xfire

post #1 of 7
Thread Starter 
Ok, my new rig will probably be:
Asrock p67 extreme4
i5 2500k
Zaward Vapor 120
4gb Corsair xms3 ram (2x2gb)
WD Caviar 500gb hdd
xfx core edition 850w psu

I will be gaming on a single monitor at 1080p.
Will be buying one 6950 now and another just before bf3 comes out.
I will be gaming with graphics very high or highest, with 4 or 8xAA.
Which option is better for crossfire in my situation - the 1gb or 2gb model?
Would 2gb VRAM give better performance at this res in games that are out now or in the near future?
If not, would it help further into the future as games become more demanding? I ask this as i aim to skip the 7xxx series with this setup.
However, the 1gb option would save me about £35

Opinions will be appreciated

For gaming at 1080p, you will not notice any difference whatsoever between these two cards. Only when you game at a higher resolution or use multiple monitors would the extra 1GB come in handy. The only real advantage to buying the 2GB version now at 1080p would be to have a more future-proof card.

Final Words & Conclusion

So first off, did you guys check the difference in-between the 1GB and 2GB 6950 versions as well, yeah ... the results are nearly NIL. The added benefit of an extra full GB is excruciatingly hard to measure, even with all games setup with the best image quality settings, hefty shaders and massive textures. The reality is that for 98% of you with today's games 1 GB is absolutely sufficient.

Why would you opt 2GB you might ask yourself ? Well, there are several scenarios, first off very simply, being future proof. In time games will be more demanding when it comes to things like texture requirements. But a more important reason would be multi Monitor gaming, thus Eyefinity. It's there where you breach any foreseeable limitation versus resolution and that's where the extra memory can come into play.

If you want your rig to be more future proof and you do not plan on upgrading for quite some time, then yes, 2GB would help you in that aspect. However, I don't believe you will be needing more than 1GB of VRAM for that resolution anytime soon.

In my opinion (and everyone is entitled to their own), stick with the 1GB version. It should serve you well for quite some time, especially if you decide to go Crossfire-X in the future.

If money isn't too tight, I'd grab the 2GB versions.

1Gb is enough for 1080p now, but as karmuhh mentioned, that will change as more demanding games are released, and if you're planning on skipping a generation that's probably something to consider.

Plus that leaves you the freedom to upgrade to a high res monitor or a multi-monitor setup in the future (even if you don't plan on it now).

Also, the 2GB cards will have better resale value if/when you decide to upgrade from them.

Yes i am buying the 6950 with the nitention to crossfire.
Dont you think that by the release of the 8xxx (or at least after the release of the 7xxx's) series ill need more than 2gb vram?

Probably not. By the time that comes out, 1.5gb might be the new standard, but not 2gb. PC games can be demanding, but with many titles being console ports, the pc versions are unfortunately being dumbed down as well :-/
