Have you seen the power consumption and the heat it kicks out? That's what is putting me off...
People always tend to buy bigger PSUs than they actually need anyway. How many people do you see with a GTX 1080 class GPU but only a 450-500w PSU? cause I don't see many, although that's all is required. Also you can undervolt the Vega card if you want, to reach similar stock power consumpton to a pascal card without losing performance. If you can assemble a PC or install a GPU, then you can move a slider in Wattman. I have a Ryzen 1700X @ 4ghz and a Vega 56 @ ~1600Mhz and I barely scrape 350w usage using a kill-a-watt under gaming load. I can bring that down to 250w under load if my CPU is stock, and my Vega is undervolted further at stock clocks.
Reference cards or not, they still draw significantly more power relative to their Nvidia counterparts, and many must therefore rely on higher capacity PSUs.
No you dont, was only an issue with reference cards, most AIB cards wont overheat and running hot isn't an actual problem
Not going to make any difference tbh. Mid range cards can only expect about 24 months lifespan realistically anyway, which will be about the right time to upgrade when the RTX tech has advanced some. I bought the 2060 and am fully aware that this card will last me approximately 24 months. £150 a year for gaming at 144hz 1440p for the next 2 years sounds good to me and is about in line with the more expensive cards in terms of price vs lifespan. Edit: It may prove a problem for the 2070 and 2080 range of cards though, my comments above are aimed specifically at the RTX2060 as that is by far the best value for money.
