Advice on some graphics cards to play Amnesia.

[helloimlouisb]

I just bought Amnesia digitally, and i was so psyched to play it. Unfortunately, the fps im getting is none to be desired, making the game pretty much unplayable, even though i also got penumbra and i was able to play that just fine (a little bit choppy still, but nothing too serious) So i decided it was time to look for a new graphics card, mine being a nvidia geforce 6150se nforce 430 (yes, i updated my drivers). A friend of mine suggested, based on my specs, that i buy a nvidia geforce 9500 GT, and that it will run a newer game fine. Can anybody maybe testify for or against this? And if against, any other ideas that are available? (My budgets around $150, so nothing too high-end please) Much appreciated.

Specs: Windows 7, 2048 MB RAM, 1.9 GHz AMD Phenom 8250e triple core, integrated RAMDAC. Anything im missing just let me know, thanks again.
