Did some research, is this correct?

Best value:

0-100$ = 750 Ti
100-150$ = 950 (about 50% faster than 750 Ti)
150-200$ = 470 (about 70% faster than 950)
200-250$ = 480 (about 5% faster than 470)
250-300$ = 1060 (about 10% faster than 480)
300-350$ = 1060
350-400$ = 1070 (about 40% faster than 1060)
400-450$ = 1070
450-500$= 1070
500-550$ = 1070
550-600$ = 1070
600$+ = 1080 (about 20% faster than 1070)

I bought an R9 Fury for 270€.

How's that for value for money?

>200-250$ = 480 (about 5% faster than 470)
Should still be 470, no reason to waste more money for 5%

Obviously, I simply inserted the card per price bracket.

In reality the 470 should be top value per dollar overall.

1080 is 25% faster for 40% more money. It's not as bad as you're making out, unless you're broke. Also good luck finding a 1070 for under $430

you're not factoring in the returns over time and purpose of usage

highly dependent on your output display

this ain't investment banking nigga

580 can be had for $100 and shits on the 750Ti.

You could probably get dual 780Ti's for $450 which beats the 1070.

Learn to take the used market into consideration. They are often even more value for money.

And I haven't even talked about used 290s and 7970s which can be had for stupid low prices because coin miners. I wouldn't be surprised if the 7970 can be had for as little as $70.

Refer to Logical Increments. Their tier lists are really reliable imo.

should put 980ti somewhere there then.
