Is it worth upgrading from 2 x CF 7970 OC cards to 3... ?

I can't find any benchmarks on 3 x 7970's but I hear people saying "they don't scale well after 3 cards".

Please factor in I am using Eyefinity 3240x1920.

Thanks!

I wouldn't because of drivers. How does the crossfire 7970 work with the triple monitor? I know that there is still the frame pacing issues present, how bad is it? Dual 7970 is still at the top of the benchmarks unless you are going to go crossfire 290, sli 780, crossfire 290x etc... I think you should stick with the dual 7970s.

It works well, my only concern being that the VRAM fills on some games when running in max / higher settings.

Yes I could crossfire 2 x 290x but then i would need to water cool them as they make an awful amount of noise or they down clock... And TBH I don't think the extra cash on them is worth it, that's why I was thinking of just adding in another 7970 card. But I just checked my motherboard and the extra card won't fit (cooler is too big on the Sapphire 7970 OC by about 3mm).

So if I did get a 3rd 7970 I'd have to water cool... Which is another thing I am toying with.

I would check the reviews on doing a triple card setup, if I remember correctly there are some issues with three cards, two and four work the best.
