nah, two years is not really old for a graphics card. it is not a very powerful card though i have not played BLR so i do not know what you could expect - seeing the system requirements don't seem like it needs much.
now crysis on the other hand is very demanding . . .
there is still a few things to try out if you have the patience, i can understand your frustration. if your running fraps while playing, give it a go without and see if it makes a difference; try lightening the load a bit.
