Hi Vertcoiners

I thought I'd ask this here too as I've been considering mining vert for a little whlie after mining another n-scrypt coin.

Some opinions please.  I currently have 2 Sapphire Dual-X R9 280x cards that I right now arranging to be send back to Amazon due to failing fans on 2 of the original 3 I bought, so I'm now going to be needing some new cards.  I've been mining months even now and I think its still worth GPU mining for a few months yet before the ASIC invade

Suggestions on good mining cards... especially for cards that don't have failing cooling fans in less than 6 months use. I think I'm only getting 2 this time as trying to put 3 in a HAF-XB case meant they ran at 70+ and an 80+ temp. I guess I'm looking at 280x cards maybe 290x depending on monies, I still haven't paid for my rig since prices crashed with the bitcoin price fall in recent month so I'm not over joyed with the prospect of paying out a lot more

Thoughts?
