A few years ago I purchased a GeForce 4 and have been using it for quite a while with it overclocked, no problems. It had run fault free until I put it into my newest PC, where I believe that a hot motherboard (due to poor contact between the CPU and its heatsink - the CPU fan had to run at 5500+ rpm to keep it at 60 deg. C) contributed to the failure of 2 capacitors on my video card. At first they were slightly bulged and the card continued to run as per usual, but then problems started occurring so I opened up my case and one of the Rifeking capacitors (6.3 V, 1500 uf) had significantly leaked...

I just retired a 2 and a bit year old Jetway PMFU533 with GSC caps on it due to it being massively unstable. The problems started in October and progressively got worse, until it was near impossible to work on the computer. There are clearly bulged capacitors on the board and most of those have brown stuff deposited on the top. Only the ones with gold writing on dark purple have gone bad, the ones with gold writing on black are ok. Below is a detailed list:

Bad:
T20A 6.3v 1000uf (purple w/gold)
T2NG 6.3v 1500uf (purple w/gold)

Good:
T2DA 10v 1000uf...
