Im returning my 780s today actually. They have audio issues galore according to their forums. I noticed my sound in game would get really distorted. Also the software is garbage it interferes with so much stuff. Installed iTunes wont open. Uninstalled works flawlessly.
I have a razer naga epic mouse and now a Tiamat 2.2- I am very happy with razer as a company. They always make me feel like a kid opening a Christmas present they way their products are packaged and the care and design they put into it. The naga epic is hands down my favorite mouse ever- expensive but great.
I am very happy with the Tiamat 2.2? And for 90$ I think that their not that expensive. I paid 170 for TB x41 and I think they sucked
