Question Upgrade from 1070 Ti for use with 4k projector


Jun 4, 2020
Hi all - I have been using a 1070 Ti for a few years now primarily for RDR2 and similar (eg Valhalla) and occasional movies (inc Blu rays). I exclusively use a 1080p DLP projector (Optoma 141x). I am thinking of upgrading my projector to a 4k model and therefore want to also upgrade my 1070 Ti in the hope of being able to play at higher resolution and also to increase my graphics settings in games like RDR2 (with the 1070 Ti I am already able to have the settings pretty high and make do with the FPS hovering around 40). I am thinking that to make the upgrade worthwhile I would need to get at least a 2060, but probably a 3050/ 3060 (I can get a used 3060 Ti for £350 - but I would not want to spend any more than that). My questions are

(1) which of those cards would be the best option
(2) is the rest of my hardware able to support those cards OK, or are there other things I would/ should upgrade. My basic spec is below.

CPU: Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz (8 CPUs), ~3.5GHz
GPU: ASUS NVIDIA GeForce GTX 1070 Ti (8GB)
Memory: 16GB (2x8GB) DDR3 799,9 MHz
Mobo: ASUS P8Z77-V (PCI-E 3.8)
PSU: Corsair CP-9020103 CX65M 650W

Many thanks in advance for any help.
