I'm a little worried that a R9 290x/GTX 780 might not do as good as the next gen consoles in 4 to 5 years later because when i first got my gtx 260 back in mid 2009 which i am still using now, it would blow all the games on the xbox 360 and ps3, games like oblivion, fallout etc. i could see a major improvement on my pc with the same games. But later on when crysis 2 came on for both pc and consoles. the ps3 could actually play crysis 2 while my gtx 260 which is suppose to be beyond the ps3 could not even play it on medium without minor lag.
If the R9 290X won't do it, the maxwell and the next amd should be able to right?
Odd i have a GTX260 and I played it on High on 1920x1200. I had AA and everything else off though and I had no issues. Was running only a Core 2 Due back then too.
Now one thing you have to understand is 1) on a PC the computer has to run the Operating system as well which is why PC's need more memory or a faster CPU than consoles 2) as time goes on Game Developers also harness the hardware better. Like people talk about how games will look better on the PS4. Honestly I don't see that happening for another year or two because they just won't be able to utilize what the hardware offers which is why games get better looking as time goes on. For example. Look at halo 3 VS halo 4. Pretty big difference on a lot of things.
And besides you can't really compare Console VS PC because PC's can always be upgraded and overclocked where Consoles can't.
There are quite a few variables to consider.
Most console games are rendered at 720p then some are up scaled to 1080p.
Computers render at the set resolution.
1920x1080=2,073,600 pixels. So right off the bat the computer is doing more than twice the rendering work.
Next you have to take into account textures, AA/AF (which console are not capable of changing) some games use 2x or 4x and are not capable of 8x or16x or32x , which also requires more rendering and memory.
So if you set the computer to the same settings the console is set to the computer would always win when it has more capable hardware.
A 780 GTX or or R290x will be much more powerfull than the new consoles,by a large margin, But if you set the game options to max or ultra it will be doing 2 to 5 times the amount of work. so FPS might end up being less than a console.
