The problem with the above performance discussion is that prices are a major unknown. Nvidia prices were relatively static between Maxwell and Pascal — about $30 more if you don't count the Founders Edition 'tax' — but from Pascal to Turing the high-end GPUs jumped 30-40% in prices, while the top model (RTX 2080 Ti) cost over 70% more than its predecessor!
Or another way to look at it, the performance gains for Turing were far lower than normal, so Nvidia shuffled around product names to hide that fact, and maybe trick some people into moving up to a higher tier than they would have otherwise. Going by pricing, the RTX 2060 was the successor to the GTX 1070, while the RTX 2070 was more a successor to the GTX 1080, and the RTX 2080 a successor to the 1080 Ti. The RTX 2080 Ti's price bracket would have normally made it a "Titan" card. So, the 2060 and 2070 didn't offer much more than 20% more performance than the prior generation, and the 2080 even less. It could be argued that some of the new hardware like RT cores offer additional performance, but games utilizing RT are still few and far between, and it's questionable how well that first-generation RT hardware is going to hold up over time.
Dang, I just got an RTX 2060 KO last week. I guess I could sell it and pick up the 30-series equivalent in a few months. I had no idea Ampere was coming out so soon.
It could potentially be a fair amount longer before they launch new mid-range cards around the $300 price point. In the case of the 20-series, they launched their high-end $600+ cards between late September and early October of 2018, but the $350 2060 didn't come out until late January, close to four months later, and the $280 1660 Ti didn't come out until a month later still. So, it's very possible that we might not see new mid-range cards until early next year. Likewise, AMD just launched their similar-performing 5600 XT for around $280 less than 6 months ago, so they may also be more focused on higher-end models this year. So, you might potentially be waiting half a year or more, unless you spend $100-$200 more for something in a higher-end bracket. I guess it's possible that we could see cards like the 2060 SUPER and 5700 XT go on sale for around $300 during the holiday shopping season if faster cards appear in the $400+ price range though.
I'm in the market and I'm doing my best to hold off;
How long do you think it will be until we can get a desktop with?;
Intel 12th gen k-series 10nm CPU (alder lake)
MB with w/PCI4.0 full support.
CPU and MB to support DDR5 RAM
RTX 3080 Super (PCI 4.0)
PCI 4.0 SSD
I'm guessing this time next year? What do you guys think?
Probably longer than that. Intel's 10th-gen CPUs just came out a little over a month ago, launching with a brand new series of motherboards, so a year from now you will likely be looking at their 11th-gen processors. I wouldn't expect their 12-gen desktop CPUs until near the tail-end of next year at the earliest, and they might not even be available until early 2022. And at least from a performance standpoint, DDR5 might not offer much over DDR4 until its been on the market a while and higher speeds become available.
The 11th-gen processors will apparently offer PCIe 4.0, and the graphics cards coming later this year will undoubtedly support it, though I wouldn't expect much out of the interface performance-wise. Those graphics cards won't likely be limited by PCIe 3.0 to any measurable degree, and the performance benefits of PCIe 4.0 SSDs have so far generally been limited to copying large files and synthetic benchmarks. At most real-world tasks, you will likely struggle to notice any difference.
