I just bought a dell 8700 from costco, with a 460w powersupply (recommended is at least 450w) and a radeon r9 270. I've spent the last couple days on the phone with dell/costco.. I'm hopefully getting a new R9 270 to test.. but this issue seems very prevalent around the internet.
I installed my old Radeon HD 5800, and it's performed completely fine.. no black screening.
Is there any sort of firmware update or something? I'm really concerned that this problem will continue even after I get my new R9 270... because of how much I've seen it reported on the web.
Any other suggestions?
