Right now, but how about next year? Or the year after? How about over the lifespan of the GPU? Say 4 years?
Right now is as good a time as any to make certain predictions. Mostly because the dev cycle is going full circle on the consoles and thus, hitting older cards with less VRAM hard.
The worst games for it (but best when it came to visuals) were TLOU and a few others. I don't feel that games will improve much more than that before people need new consoles. The problem is that both of these cards will need settings dropped from the beginning to be able to max out 1440p with high refresh any way.
It's like I said before. Some cards need more VRAM. Some cards just don't. It is all about getting that balance correct, which AMD seem to do quite well. They certainly give you options rather than none, and planned obsolescence seems less of a thing with AMD.
Bottom line? you would be silly to buy a 7700XT any way. For £50 more you get so much more. More VRAM, faster die, higher VRAM speed and higher bandwidth. Which when you consider Nvidia charge £100 for more VRAM and little else? makes the 7700XT not worth bothering with.
