I replace a older card in which the fan be grind . the older card be a 4200us with 128m of memory , but be much larger in physical size compare to this card . the new card work well . I do not notice any performance improvement , but it work without flaw . the best thing be that it run without fan . I expect to see some benefit due to the memory . I try to run hd video , and this card will not run it -lrb- I do not expect it to -rrb- . but , my processor -lrb- p4 2.8 single core -rrb- be a bottleneck as well . overall , this card will get the job do , and allow I to keep this system run for another year or so .
