GPU Upgrade for an old system?

Hi,
I'm looking at an old PC for a family member which needs to have a new GPU to replace the broken one which was in previously. I've yet to see all the details but I believe its an Intel 4th Gen i5 from 2014/2015, so I would guess this would also be DDR3 memory.

The budget for a new GPU is £400-450, so that would put it in the realm of a 4060Ti or one of the 6000 series cards such as 6700XT/6750XT/6800.

The main issue for with this I guess would be that the system would be bottlenecked by the CPU. Uses for the PC are some gaming, editing drone camera footage and other general use on a 1440p display.

How much performance is wasted with an older CPU like this, would it just be better spending £200-250 on a 6600/6650 or would there be a significant benefit to going with the 6750/6800. I've had a look at these bottleneck calculator site, but to be honest I don't know if a lot of these are just junk anyway?

Many Thanks
 
Unfortunately, the reality is that this varies, depending on the game, particularly the age of the game, but playing at 1440p will help push the bottleneck out. What's the likelihood of the graphics card going to a new PC in the near future?

Personally, I'd get at least a 6700/6750 for 1440p, regardless of the CPU, but the RX 6800 @ £450 is a good choice too and would appreciate being paired with a 12400F/5600X or something like that, if/when they upgrade.

In some games, a 4th gen i5 is going to choke and barely be playable, but that's just how it is, a 6700/6750/6800 is still going to have better longevity than a 6600.

In testing that hardware unboxed did, the AMD cards had a lower CPU overhead, so with a weak CPU I'd be going in that direction, but RandomGaminginHD found that frame generation on the 4060 Ti had some interesting results with a 13 year old CPU.
I would think that at some point a cpu/motherboard upgrade would be on the cards but I think at the moment they just want to get it up and running again. I guess spending a bit more on the GPU will give that extra headroom for future upgrades.

I don’t know yet what type of games they will be playing so I don’t know if they are cpu core dependant,etc.
 
Here's an i5-6500 tested with a RX 6600:

Interesting video. Funny how for years, always used to read about Alienware machines being the absolute dogs boll#cks of gaming PCs, always seemed super cool and expensive but great if you could afford them. I hardly hear about them now, I wonder if things went downhill when they were purchased by Dell.
