PCIe 2 . 0 x 16 slot actually does not bottleneck your card ' s performance well , theoretically anyway . should you see weird stutters or the card struggling to keep up , turn down shadows andor Antialiasing a bit . a quick check list to see that a new card will suit you 11 . is the case short enough for your card ' s length ? 2 . some cards take 2 or 3 slots of space i . e . how ' thick ' the card is , do you have sufficient space ? 3 . 1060 ' s are quite power efficient , your 460 w PSU should be ok with it . be very careful if you wanna overclock tho , because that is a lot more demanding on power supply 4 . your PSU should already have a 62 pin connection , so you check either a new card uses a single 68 pin . OR , if the new card requires 2 x 68 pins , just use a molex i . e . 4 big pins 62 pin adaptorcheck the above and you should be good to go !
