RTX2070 — Are They All the Same?
I've had my 7900X system for well over a year now, and I am still using the GTX970 I bumped from my old system because I didn't want to spend dollars for a new card that might soon be superseded. Truth be told, I am not seeing noticeable performance issues, but I spend a lot more time with Photoshop than Premiere Pro, and the Puget Systems tests do not seem to indicate massive advantages with newer cards for Photoshop at least. But it is starting to feel crazy spoiling the ship for a ha'porth of tar, so I am finally going to replace the aging GTX970.
I can't justify a really high end RTX card, but I want to see a worthwhile improvement, so I am thinking RTX 2070. What I don't understand is the difference between different manufacturers? So the only criteria I can think to apply is looking for a card with similar outputs to my current card so I can use the same cables.
Q) Are there other things I need to think about and consider?
The rest of the system is:
i9-7900X
ASRock Fatal1ty X299 Pro Gaming i9
64Gb RAM
Two Samsung 960 PRO 512Gb (plus a bunch of other SSD and HDD)
Corsair 1200W Platinum
In a Coolermaster Cosmos case
I use three screens via HDMI, Display Port and DVI.
Main screen 2560 X 1440
Peripheral screens both 1200 X 1920 (portrait mode)
It is unlikely that I will ever replace these with higher resolution screens.
I don't play computer games, but it is not out of the question that I might try one just to see what the graphics are like nowadays. The last computer game I played was the original Doom, so I'm sure things have moved on a way since then.
