Don't buy Nippon Chemi-con KZG. Although it's a reputable manufacturer, KZG and KZJ series were bad. Also don't buy capacitors from ebay/China. Most from remotely reputable brand is counterfeit.
but it read 1(7) 5K and gpu capacitor read 6(k) 8P.
You should not bother abut date code or lot number. You should care about capacitance, voltage and ESR being not higher than original (from datasheet).
