6970x2 or 7970

post #1 of 13
Thread Starter 
I recently built a new rig...sabertooth mobo, 8350 cpu, 16gb ram...and now I need a new GPU. I can either get two 6970s for 350 or a single 7970 for 300 or two 7970s for 590 but that is kinda a reach for my budget. I have never ran sli or crossfire so I don't have any idea how well it works. Some people say its great and others say it sucks. Anyway what would you experts recommend for my setup?

No microstutter issues here, works great with my rig. Depending on who you order from, I like Amazon, can you order 2x 7970s and play around with them for a week or two and make your decision before 30 day return policy is up.

I would start out with the single 7970 card solution for these reasons:

  • 7970 is newer technology over the 6970s. Granted, it's not night and day difference but for example, it does tessellation more efficiently than the 6xxx series cards. And tessellation is becoming more important with newer games.
  • More Vram - becoming more important with newer games. Even with 2 6970's you'll only have 2GB vram (not 4GB).
  • 7970 is a good card on it's own for today. However if you chose to crossfire it next year or so you will have a setup with better tech and less heat than 2 6970s.

Need a little more information.

What's your PSU? Can you run two Xfired 6970's on it?
If you're going to go crossfire 6970's, you have to also be sure your case isn't cramped and has good airflow--crossfired 6970's give off a lot of heat!

As far as micro-stuttering issues with crossfire, I can't comment. But you should keep in mind things always do get a little more complicated when crossfired/sli'd.

However, dual 6970's do beat out a single 7970 in performance. So really, do you care about using more power/generating more heat/ adding possible complications with crossfiring for a performance boost?

No microstutter here. I would do as rageofthepeon said and play with two? But I'd just buy the one 7970 if I was you.

My new case is the in win dragon rider, it has very good ventilation and with 6 fans I should be able to disapate heat fairly well. The only thing I carried over from my previous rig is the PC power silencer 750 PSU and it is crossfire capable.

People should stop using this argument.
He was probably told the same upon purchasing a 6970.

OP, You need to decide how long you intend to stay with the card(s) for. If you want something to last a year or so then crossfire, if you want longevity then get a 7970.
If you don't intend on playing the latest and greatest that are released then you could get by with one 6970 and hold on for the next gen of GPU's but it could be a while still until we see them surface.

What will you be using your computer for?

You can get a 7970 now and upgrade later on.

Except he is thinking about the 6970 right now and not 2 years ago. Argument is valid.

Having just gone from crossfire 6970s to crossfire 7950s, I think I can be of some use here. Personally, I'd go for the 7970. It will produce FAR less heat and use FAR less power than the 6970s, while having better performance in actual games when overclocked. If you don't plan on overclocking or you don't give a hoot about power consumption, noise and heat, go for the 6970s. It's as simple as that, to be honest.
