that card is quite old although still supported by nvidia main driver. when the card first come out it was considered as the upper low end card. it will play most games but don't expect to push it. even if there is other cards to consider i will not go past GTX650/GT740 (a bit ahead GTS450 in performance but will consume much less due to build on smaller process node than GTS450). why did you have 5GB of RAM?
