2 6970's or 1 7970 - Page 2

post #11 of 36
Thread Starter 
Well, let me ask! "Which will be better for 3 monitors?" I'm just curious how you hook up 3 monitors with the 7970?
post #12 of 36
1 7970 for sure out of the two proposed options, but like someone already mentioned, I'd wait until the 580 has a nice price drop and go for that. Aside from avoiding any xfire issues, the single gpu is better imo because it's more future proof - when it's time to upgrade again in a couple of years, rather than spending a ton of money buying the best of the day again, you can then buy what will be a significantly cheaper 7970 again and run them in xfire so while the 2 6970's may have a better price/performance ratio right now, the single 7970 is better in the long run.

It has 2x DP, 1x HDMI and 1x DVI. I don't know if all can be used at once, but if you at all considered Eyefinity when you bought your monitor, you should have DP and either HDMI or DVI (or all). I'm guessing both DP ports and at least one of the other can be used at once.

Tbh, i regret it.
6990 / crossfire no more for me.

You regret it because you have to run single card for a week or 2 for new games?
post #15 of 36
Coming from an xfire user of 2 6970s...get the 7970. In 6 months you can get another 7970 if you need to...but trifiring 6970s is a little ridiculous.

Even when CrossfireX is working properly, you'll rarely see 2x scaling outside of benchmarks. Even when I try running Crysis, my GPU usage hovers around 50-70% in game, fps is not really steady at 40-70 fps, and that's the most most GPU-heavy game ever made.
There's the extra heat, you need a really good case to not suffer from noise issues and becoming an oven. My Twin Frozr IIIs were almost silent in my Raven 03, but in a CM 690 II the noise is quite noticeable (yes, I have tried different fan setups).
Then there are CrossfireX artifacts, and after that you have space and power usage.

But all of these problems pale in comparison to microstutter, it's an ugly beast that rears it's head in nearly every game I've played if I turn up the settings too high.
Nvidia was no better last time I tried gaming on all of 460 SLI, 560 Ti SLI and 570 SLI in november.

CrossfireX/SLI sure looks good on paper, but in actual use it's not really that good in my experience. There are people who'll never go back, I'm definitely not one of them. Now that 7970 is able to provide the performance I need to get 120fps with high settings, while also overclocking like a beast, and fixing the 6000-series' slight problems with dx11-games I'm getting one. There's really no contest.

Those of you downplaying crossfire obviously lack the patience required to own a multi-gpu setup. If you're not inherently a tweaker, crossfire isn't for you. I've had my 4 6970s (running 3 of them atm) for nearly a year now and they've done absolutely fine. The games that don't scale well, don't NEED to scale well because a single 6970 can handle them anyways during the downtime before the CAPs are released. I've never experienced any issues I couldn't resolve with my cards. I think it's funny that some of you are saying that crossfire is bad, yet you recommend that he gets a single 7970 now, and another 7970 down the road for a crossfire setup to save money. Crossfire is for people that want top of the line performance for a fraction of the cost. If you're a good enough tweaker and you set frame limiters in your games, and do your due diligence, you won't have ANY problems with a Tri-Fire+ setup. I run BF3 @ 5760x1080 @ 60fps all day long. When I drop down to 1080p @ 120hz, I easily keep my minimum fps above 60fps even in big 64 player multiplayer matches and my average is 120+ fps. Those of you willing to sacrifice performance to move to a single card, more power to you. However myself... I'd rather keep my Tri-Fire setup which performs about exactly at the speed of dual 7970s @ stock, however all 3 cards are running at 950/1425 to do so, but it's not a big deal.

I get about a 14k P score @ 950/1425 with a 2500k @ 4.7ghz which is what a 7970CF setup gets, and a GPU score of 17.5k which is exactly what the 7970 gets in CF @ stock. Yes you can OC them and gain another 20-30% if you win the 'silicon lottery', but if I have to buy 3 7970s to significantly beat my setup, there's no point as it's absolutely too much of an investment to make, and would simply be replacing 1 tri-fire setup for another, which isn't what I want to do when I upgrade or side-grade.

A single 7970 is way more playable than 2x 6950 in CFX. How do I know? I've tried both the last 24 hours.

Yeah in most testing they did little more than the pair. I guess it depends on how far yu'd be pushing them.
