Hello,
I have dual 7970s in Crossfire, a guy's offering me 300 eu for them. I bought them in May 2013, so they'll be 2 years old soon. They're the cheapest version (sapphire dual X). If I sell them and add 60 eu, I can buy a GTX 970 Asus Strixx edition. I have a custom waterloop, and a GTX 970 full waterblock costs 80 eu. I play at 5760x1080.
Will the decrease in performance be much? Is it worth it?
Thanks :)

The crossfire solution would ultimately be the best option in terms of raw power. You do of course experience scaling issues common with dual card set-ups. And you also require a much larger fluent power supply, resulting in a larger electric bill.

If you could afford to SLI two 970's, now that'd be a nice accomplishment for higher resolutions.

Raw power, yes, but how about other things? Overclocking, lower TDP...

You might not see much of a hit at all in performance since the 7970's have ONLY 2Gb RAM, and the 970 has 4Gb which at your high resolution would come in real handy.
On the water block for a 970, total waste of time and money for a 145watt card (aka, no real Need for it, BUT you can always do it for looks n fun). I'm running SLI STRIX 970's 70C (50% fan) top card 65C (47% fan) on bottom card. There are no heat issues that need water to solve here....

BTW, if you are leaning to water cooling, get a cheap 970 since the extra you pay for the STRIX cooler is just going in the trash any how when you goto water..

The 7970s have 3gb of ram. Reference. A sapphire model even has 6gb. And they have a 384 bit memory bus. But i get what you are saying. I'd get the asus card because of the zero fab priofile and reference design. It's the last time I don't buy a reference card, those universal waterblocks SUCK.
I still kinda have to make up my mind, but thanks for the replies tho.
