I want to buy a r9 290 for $200 on Ebay because ill be stuck getting the r9 380x or r9 370x on launch, and i think the r9 290 will out perform 380x because its re brand of 280x. The final factors are HBM and dx 12. hbm doesn't matter that much because the r9 290 already has 4gb vram and decent bandwidth. I will be getting 1080p Ben Q display for my pc. Should I wait for r9 380x or just buy r9 290 right now for a similar price to r9 380x on launch?
