I've been a ATI user forever. The only other cards I ever had we're old Voodoo's.
I recently got my hands on a R9 290 at a reasonable price. Card ran amazing benchmarks, stress tested like a champ, did get a little hot and though it was loud, it was nothing compared to what everyone says about it.
Then I started testing it in game and the problems showed up. Black screens over and over and over. Sometimes it took 15 minutes, sometimes it took 2 hours. So I started looking into it and found out a huge amount of people we're having this same exact problem. Apparently it's caused by the bad Elpdia memory, all if not all of us who got black screening cards we're unlucky enough to have Elpdia instead of Hinyx.
So I sent it out to get checked, tested on a other PC to see if it was just me but no. The problem is real. First time Ive ever had problems with ATI like this.
Now I got my money back but I'm without a card because these things are literally sold out everywhere. And I'm thinking of making the jump. It pains me to do so but I feel like it could be the right thing to do right now. I feel like the GTX may be a little less powerful, but much more reliable at the moment.
I've been reading reviews and watching videos on both cards and how they match up against each other and mostly it seems like the R9 pushes ahead in almost every way. Still, after my bad card and all the other reviews about many R9 290's being inconsistent in how they perform I'm starting to double guess my loyalty to ATI.
One nice thing that really attracts me to the GTX 780 Asus is the non reference cooling, I've always had non reference coolers on my cards. They give me a safety net if I ever wanna overclock and just make me feel "safer".
Anyways I'm gonna stop typing since this is getting really long! I'm just looking for some help making this choice. I know they're both great cards but maybe someone here has had experience with both. Or has been in the same situation as me ( a long time ATI fan ) and switched over.
There is also the issue of Mantle. Is it worth investing now for a new API that should be gaining a rise in popularity over the next 1 or 2 years?
