Advice on buying HD 6950 vs actual Crossfire 5770

[JAG]

Hi guys, need you advice on this, right now I have a Crossfire 5770, it runs ok, mostly on 35-30 fps with two 1920x1080 monitors, I'm planning to connect a third monitor 1366x768 but I need to buy an active display port adapter to use it, and to maintain crossfire activated. I've tested connecting the third monitor on the second card deactivating crossfire, and the sim runs really slow 5-10 fps. :(

 

However I see the HD 6950 2GB version, is in a very affordable price, so my question is:

 

If I buy the the display port adapter, crossfire will be active again, but will I have 25-30 using the three monitors, or it's a very large resolution even for both cards in crossfire?

 

With the HD 6950 2GB can I have the three monitors connected, with a very good framerate?

 

Thanks in advance

I'm not sure Crossfire works for LOFC or DCS. Probably not, as other users' experience show:

But HD6950 is a good card. It can be easily unlocked to full HD6970. If you intent do to it, I recommend to buy one with standard amd/ati-layout. It is much easier to get bios for standard 2GB/HD6970, than for some special iceq/frozr/toxic version...

It can be easily unlocked to full HD6970.

 

As an owner of a 6950 I would have to disagree, they used to be easy but AMD is reported to be laser cutting the additional shaders in the current production runs of chips.

 

However the newer 6950 cards have better cooling and can potentially overclock above their older SKUs, with overclocking leading to more significant gains than the shader unlocks.

 

Bottom line is the 6950 2GB is a damn good GPU but do your research very carefully if you are expecting to do a shader unlock in addition to overclocking.

Hi, yes the seller says the same about the card, the newer models can't be unlocked, but overclock it a little bit is not a bad idea. :lol:

However my biggest concern is about using those 3 monitors and still having a good framerate, because will be really dissapointing to buy a new card and still having low fraps.

 

Thanks guys :thumbup:
