I need 20 meters of ethernet cable for my pc.Will I lose performance because of the length?Will it affect my gaming(latency,ping) and downloading speed?Do I need a Cat 5,5e or 6 cable?
NOPE. Ethernet are good for up to 100 meters, you only lose latency when you have to go through extra "boxes." Cat5e or Cat6, the price shouldn't be that far apart.
At that distance Cat5E is just as good as CAT6. But Cat6 is so common now it should be the same price. The speed of the cable will far exceed your internet speed so no worries.
make sure your switches and router are gigabit to maximize speed.

Your ping will go up by about 100 nanoseconds using a 20 meter long cable vs a 1 meter long cable
