Ok, running Optifine at (mostly) the lowest settings, I barely managed to survive the first night (but that's probably because of my aggressiveness ). Anyway, I averaged about 15-30 FPS. 30 is about the minimum you would want to have. Due to the lag, every time I placed a block it placed 2 blocks. Really annoying. And you don't get the best graphics of course... I'm not sure if I could live with it. Seriously. If I were you, I'd get a new computer. You could get the XBox version, but it's not as good.
