I think mine has a very slight coil whine, nothing to bad unless your head is next to the PC.
Still, I'm considering returning mine under the 14 days satisfaction, (even though I'm likely to loose £150.) For only really one reason
I'm a little disappointed with the performance at 5760x1080, mainly in GTA5 which is my No.1 game atm.
It's by no means a slouch, but it struggles to stay even in the 30s with most of the settings turned up.
Other games are good to great, but this one is a little disappointing, and with only the 4gb limit of the card a little worrying.
Now the problem is will even a single 980ti be able to give me good frames at 5760x1080?
Is my i7 2600 holding me back?
Should I hold out and just get another Fury X when stocks and prices come down?
Going dual card would require me to upgrade my mobo, but if my 2600 is holding me back maybe I should anyway?
Any how the card really is great I really dont want to swap it as it looks amazing, but if I can get at least another 8-10 fps in GTA with a diff card, I may consider it.
