Usually, polymer caps replace electrolytic, no ceramic caps. Ceramic capacitor's capacity range is lower than 10 uf (and usually much lower than that). SMPS in either video cards or MoBo use several caps in the order of 1000 uf, usually electrolytic with low ESR. But electrolytic have a very limited lifetime (even worse considering the low quality components that are used). Solid polymer capacitors have a MTTF of about 600.000 hours @ 65C, so they will last as long as the board.
