Sapphire's R9 290X / 390(X) with 8 GB if the price is to my liking. My monitor supports FreeSync so I wanna get rid of my green card.
However, that would be just temporary until AMD's new generation comes out. Their current power consumption would be a no-go in the long term for me. Unfortunately the Fury cards are just too expensive.
An additional 10 or 12 inch subwoofer is also on my list, but it would be better to consider it once I've got all my stuff set up. After measuring the speakers & EQ'ing to my liking I'd decide if the kicks are strong and clean enough.
A dishwasher. After washing by hand for like 3 years or more this is gonna be a godsend.
I could also need a new house telephone, hairdryer and maybe a telephoto lens for my DSLR.
Other than that I'm just looking out for a few longer A/V cables since some will be too short once I get devices off the desk.
