Crossfire R9 390 or Save Up

[Rayzer_116]

Hi I'm wondering if I should get another R9 390 8gb or save up for a better single gpu like the 980/ti.

Thanks

Performance wise where CF is supported the 390's would win, to me a single card is always better but really that is a personal choice.

rolli59 would a 750W PSU be able to manage the dual R9 390? Or would I have to upgrade that also?

It is at the low end even if high quality, here is a test with 2 x 390X hitting over 800watts from the wall http://www.tweaktown.com/tweakipedia/91/amd-radeon-r9-390x-crossfire-4k/index.html it is just to close for comfort since 805watt from the wall on their 90% efficient PSU is 724.5 watts load on the PSU. I would say a minimum quality 850 watt unit.
