As Stated I currently have 3 7970s running xfire. I have some money to burn (1500) and was thinking of upgrading to current GPUs. Would i see a difference in performance on highest settings with a newer (current) GPU in SLI or Crossfire??? I have a Steambox i am starting to build with extra parts i have laying around, including the use of the older GPUs.

Mobo: Asus Max V Formula
CPU: i7 3770k @4.6ghz
Ram: 32GBs Corsair 2100
GPU 3x7970's
Monitor 3x Dell u2410


Thanks!

Since you already have the 3x7970, they are best, but a 2x 780ti will be a good bit faster.

Lucky :(  Wish I had money to blow.
I would definitely go with the 780ti since it out performs both 7970 and 290x.

The R9 280x is a re branded 7970. You have pretty current GPUs and I can't recommend replacing with newer cards. Although the performance might be a little bit faster, it won't out perform your triple xfire set up.

Some bench marks for you

You can probably get upwards of $350-$400 for each 7970 on Ebay. I recently sold my two 7950 Flex cards and bought an MSI gaming 780ti. The cards a beast and faster than the two 7950s in Crossfire. The 290X is a powerful card and some of the aftermarket coolers do a god job of keeping the temps in check. Mantle and the fact that the new gaming consoles use AMD GPUs might mean better performance and more games being tuned for AMD. But as of right now, the 290 and 290X are a lot more expensive than when they were first released.
A 290X with a good cooler costs $700+ same as a 780ti and the 780ti, in most cases, is faster, cooler and quieter than the 290X.
The 290X has 4gigs while the 780ti has only 3 gigs. Right now the extra gig makes practically no difference but certain games are already creeping up on that 3 gig mark.

I've taken all these things into consideration and ended up getting an MSI gaming 780ti anyway. It's a great card and got a 9.9 review on techpowerup.com if you want to check it out.

2X 7970 is slightly slower than the 780 Ti. A third 7970 will kill the 780 Ti
