Best Budget Gaming GPU for £125-150ish

[shheah]

Current system specs:

Intel Pentium G3258 @ 3.20GHz
8GB DDR3 RAM
NVidia GT 1030

I have a £75 quid amazon gift card. I wondered if I could potentially upgrade part of my system to help with gaming performance. Right now im struggling to play Resident Evil 2 Remake...I know my CPU is under requirements but I was hoping with a slightly better GPU I might be able to tweak the settings to allow me to play this game.
I tried with my current setup and, of course..it was laggy and stuttered.

Any advice on what the best GPU might be for a budget? (£75)

Thanks in advance! (I know it's not much to work with..)

Are second hand GPU's trustworthy? Im Sceptical..

Since you're using a a low end card currently, what's the rest of the system like? PSU capacity and case size may limit your options.

My budget has gone up to around £150.
My PSU is a Corsair CX450M.
Motherboard is a Gigabyte GA-Z97P-D3
I'm just wondering if I'll suffer bottleneck ING is I were to go ahead and get a 1650 Super or something similar..? My CPU is a bit old by todays standards.. What do you think? I'm by no means a tech wizz with this sort of thing..!

I see your point.

Being very new to all this - would it be possible to grab second hand versions of a 1650 super and, presumebly, an i5 CPU for around £150? Maybe I'm way off..

My motherboard won't accept AMD processors.. I'm told. So I'm stuck with the slightly more pricey Intel chips..

And yes, my cpu is 3.3GHz..dual core.

I've got an SSD, the game is installed to that.
It's a CRUCIAL_CT275MX300SSD1 (250GB)

Remember the 125 gift card is only got amazon. But I could stretch to maybe 30 quid extra from my own pocket to get an i5 from CEX, if that's what you were advising..
Will I need to buy new cable for my PSU? Or would the graphics card come with sufficient cables?
I got an extra stick of 4gb Ram recently, but it didn't seem to affect my issues with the gameplay on RE2. I suspect something else is contributing to the performance issues..

Sorry, I got a bit sidetracked yesterday. It's, as far as im aware, just a stock cooler on my CPU. My PC case is a reasonable size...i couldnt tell you what the dimensions were unless I measured it properly.. I seem to have a good 11-12 inches though at a glance!

Edit: I have 2 x 4GB RAM
