Gigabyte WF3 7950. Crossfire or no?

post #1 of 18
Thread Starter 
I've made numerous changes to my PC lately, and the majority of those will last me at least 4 years. However, even with the 7950 I notice some lag in games (I mean spikes, nothing constant). It's most noticeable in BF3 with explosions, and Borderlands 2 with depth of field. My real question, is will adding a 2nd 7950 help, or is this a limitation of the game engine? The card runs great with 3D Mark Vantage, and mostly fine in Unigine Valley. (I'm also attracted to the 3 games still being offered).

Also note, I do not plan on upgrading to Volcanic Islands this time around.

If I could get a reasonable price for this one I might sell it. Though I am curious why you say the 7950s don't match?

I'm not sure why he is saying the 7950s wouldn't match your system. With the recent fix of 13.8 and newer AMD drivers. I'm finally enjoying crossfire in all it's glory without any negatives that I can see. (was not always the case in the past)

I'm running 2 Sapphire 7950s with a strong 750w PSU on 2560x1440p and I can max out almost all games over 60fps. When they don't max out it is usually a game that is really heavy on CPU power and you would have me beat by a huge margin in that area. So if you are at 1080p you just set games to max and play. You are still open to go eyefinity or larger rez and good for a couple years in the future.

I wouldn't even try to sell your card right now when people can buy them for $200 range with 3 free games. You would have to take such a hit on the price and it is still one of the top cards.

2x 7950s beats out an GTX Titan, even before overclocking.

Only negative to note: if you where overclocking a single card you usually won't be quite as high with the heat restraints. I just run my at 1050/1375 for 24/hour stability and usually won't go over 70 degrees on the top card. You can push it higher than that, but I try to stay on the conservative side. I was at 1200 core on a single card.

Just do it. The wind force are great cards. I had a two gigabyte 6870s WF3 and loved them.

Honestly I don't mind. 1.25 volts is enough, I can hit 1130 core clock, though I don't 24/7 it.

You can unlock it easy as pie. I did. Let me know if you need me to mod a bios i have 3 wf 7950 rev 2 and they are top 3 or so non ref 7950s IMHO, and are great miners as well.

The vapor-x cards probably have the best cooler though.
