Yeah that's mentioned in the article, hopefully the new run is representative of an overall improved software situation and they're not specifically targeting geekbench results.
But then I guess even if they are targeting geekbench then this run is representative of the performance of the GPU if they're able to optimize for specific games anyways.
I've been thinking about doing this exact thing too but prices for the BC250 have gone up like 50% in a few months. A lot of ebay listings are now people selling build kits with 3D printed cases and dubious power supplies bundled in for an even more inflated price.
Still significantly cheaper than a Steam Machine but if you're thinking about pulling the trigger on a BC250 you should do it relatively quick before Youtubers start making videos about the idea (again) and everything gets more expensive (again) lmao.
