My System Specs

Default considering crossfire

So I am seeing 6970's go for pretty cheap these days, what with the advent of newer generation GPUs.

My question is, would it be relevant to add a 2nd card in crossfire to my current 6970? I know crossfire always has some hiccups and what not, but for people with experience using it, how has it been in recent updates? Would such an update be enough to stave off performance decreases that are coming up with future games that could potential be more demanding? Keep in mind I also use 4 displays and game in eyefinity wherever possible. Also see my specs to see my system if you need more info.

The thing that has always kept me away from crossfire is the problems that can arise from using two cards. I haven't had two cards since my Voodoo2/Intel AGP set up on my PII 400mhz from back in the day.

I had 2 series 6 cards Xfired on my CHV and I had a lot of problems with tearing at my desktop,Games not loading Games would load then crash,etc,etc.I"m running 2 560Ti"s in SLI and I have had zero issues with anything I throw at it.Just my 2 cents worth.

I've always had issues with both Crossfire and SLi, I think it was primarily due to running multiple monitors. Granted this was 3 and 4 series Ati cards and 6000 NV cards back before SLi even supported multiple monitors, I'm sure they've gotten their act together by now...

one would hope?

I had serious screen tearing with my 5850 on 3 monitors. That went away with my 6970, and it runs fine pumping juice to 4 monitors.

I don't suggest it. You can go read my thread of crossfireing 2 7970. Nothing works in CAT12.4 and the real performance boost i have seen was in Alan Wake Car12.3 with Caps12.3 But I had to disable ULPS. And I had to much around with my PC for 6 days. Dawn of War Retribution had a 30% boost in minimum frame rate score. And I read that crossfire with 6 series is not better. So if the cost is really low and want to have fun and like tinkering with PC than go a head. If you expect that adding the second card you will get 20 to 80% imprevoments in games with minimal effort, like I did, I highly suggest that you don't waste your time.

Here are my specs:
CPU: I7 2600K @ Stock 3.4 Ghz (for now)
MB: ASUS P9Z68-V Pro Gen 3
GPU: 2 x Saphhire Refence Radeon HD 7970 3TB
RAM: 16GB 4x4GB Gskill PC-1600MHz
PSU: XFX Pro Series 1000W Platinum

Nvidia is better than ATI when it comes to multi gpu's, still some quirks though. I'd suggest getting the fastest single gpu you can afford.

Agreed that is the best way!

If you don't mind dealing with some x-fire issues then grabbing a cheap 6970 (I would go used) would be a great bump in FPS in most scenarios for a relatively small investment. Otherwise my suggestion is if you need more performance sell your 6970 and get a gtx 680.

I had no issues with crossfiring my 6970s when I owned them. My only gripe was the sub-par drivers that AMD releases in general. The only thing you may run into issues is playing older games, seems a lot of them don't like crossfire (see GTA IV as a prime example).
