Are my specs good enough to play Soma?

That card is somewhat better, but I think it can be configured with less VRAM than the 8800? So it might be able to run the game with slightly better settings, but if less VRAM you would have to run with lower texture/shadow resolution.

Your computer would be more in the minimum requirements than in the recommended. Can't say for sure but I think with the this card you can expect around 30 fps in 720p, a bit unsure exactly how much you would have to turn down the settings. When I experimented with low end machines the by far biggest boost comes from lowering resolution. In terms of stuttering due to texture loading lowering textures and shadows will have the best impact on improving performance if you have 1GB or less VRAM.
