[SOLVED] Upgrade from RTX 2070 to RTX 3070

Sep 12, 2020
Hi, I'm interested in upgrading from my current RTX 2070 (original version NOT the super version) to the RTX 3070 when it releases. However, I have a few concerns as I do NOT want to have to swap out ANY other parts in my computer to make it work efficiently (ideally).

My major concern is will my PSU be sufficient?
And my second major concern is my motherboard only supports PCIe 3.0 and I REALLY do not want to have to get a new motherboard as that pretty much means completely dismantling my setup and rebuilding it and that's just a ball-ache I'd really rather avoid. Not only that but it will also add additional cost not only for a brand new motherboard that supports PCIe 4.0 but also for a new processor as well as the current generation of Intel processors do NOT support PCIe 4.0. So yeah...I'd really rather avoid.

I game in 1080p with a 144Hz 1ms monitor currently but would like to be able to not only futureproof my setup for Ultra settings in games for at least the next few years but also experience Ray Tracing to its full potential instead of the rather limited capability of the RTX 2070. I'm also looking to buy a 4K monitor at some point in the future as well although a decent one that supports more than 60Hz can be quite expensive so I'm not in any rush.

Now, currently, my RTX 2070 supports High-End to Ultra settings in MOST games with above 60FPS on 1080p. The issues start to arrive with Ray Tracing where I have to enable DLSS to experience 60FPS. Also, the new Microsoft Flight Simulator barely manages 60FPS on High-End (not Ultra settings) at 1080p resolution. Obviously with the next generation consoles coming out I'd imagine developers are going to be beefing up their games a bit more where they can and I'd like to future proof my system for years to come so I can experience (and enjoy) High-End to Ultra settings in the most intensive of games to come (I am not the type of person to be content running something at bare minimum, or even medium settings).

The RTX 2070 may be more than enough for now but the RTX 3070 outperforms the RTX 2080 Ti at a fraction of the price (and the GPU inside the new Xbox One X I believe is closer to the 2080 in performance than the 2070). In other words my current system would potentially be outperformed by the next generation Xbox whereas an RTX 3070 would put me back in the lead for less than £500. And hopefully futureproof me for at least the next 5 years or so as they're not going to be releasing another console before 2025 I wouldn't imagine.

Here are the specs I'm currently working with:

I am looking to upgrade to 32GB of RAM as well, as well as install another M2 SSD (at some point). I am also running an external 4TB USB 3.0 SATA drive. Would my existing setup allow me to upgrade to the RTX 3070 and not require me to upgrade my PSU or motherboard? From the YouTube videos I've watched so far they say that any bottleneck between PCIe 4.0 and PCIe 3.0 would only be noticeable on super high frame rates at 1080p. My monitor only supports 144Hz anyway and that's more than sufficient for me. Like I said I am looking to upgrade to a 4K monitor at some point too where I hope to be able to achieve up to 120Hz. The RTX 3080 would almost certainly require a beefier PSU but the RTX 3070 only uses slightly more wattage, from what I can see, to my existing RTX 2070.
