I bet you never looked at current listing of used GTX 980s sold prices over the last few day but the average price people buy used GTX 980s was £200 range.
Used R9 290s were sold in £150 range average price and used GTX 970s were sold range from £150-£180 average prices.
Look like prices had gone up over the last few months because of brexit.
Kainz have tight budget probably less than £150, he cant afford a used GTX 980.
Best wait 2 hours to read reviews first before reach conclusion.
Pascal seemed the best cards for quiet PCs and HTPCs because of very low temp at full load.
When I had MSI GTX 970 Gaming, fans was spinned in every games when temp reached over 60C, one game DOOM saw my card ran very hot at 85C. But everything changed with MSI GTX 1070 Gaming X I was very surprised the fans did not spinned in lots of old games when temp was 55C. I ran MSI afterburner to manually tuned fans to running all time and tested many games, when I tried Star Trek Online and I was stunned to see temp was 35C which is 2 time lower than GTX 970.
I absolutely loved my MSI GTX 1070 Gaming.
We will have to wait and see to reviews see if Pascal temp on Samsung 14nm are lower than TSMC 16nm or just much the same.
