I finally installed the GTX 1050Ti and ran some rough & ready tests, now though I did not previously time the CPU only processing I have to say I am impressed.
The same more modest upsizing by dimensions took 58seconds…it felt much quicker than CPU only.
Then I gave it a ‘horsepower test’ of a 4x upsize, this took 2m 10s which considering the 4x setting was IMO nice to see and the resulting file (TIF to TIF) was a whopping 461MB
So, as it stands I am well pleased with the investment.
PS interestingly ~ the resting temp of the GPU is 34 degrees C and it maxed out at 54 degrees C so barely breaking a sweat :lol: Plus and possibly my imagination the PC just seems a little quicker responding in general compared to before doing browsing. FWIW I am not a gamer, so very unlikely to stress the GPU
