Yeah!
Nvidia has always been the best… 
I remember, about 2 years ago, dipi and I went to this Maya convention in Boston, and they were showing the release of the NVIDIA Quadro FX. It was amazing stuff.
On some tests the nVidia will outperform, on some tests the ATI will outperform Once your frame rates start going over 60-70, you probably won’t notice a 4 or 5 fps difference. Though such frame rates in Doom 3 are a good ways off hehe.
Both ATI and nVidia preform well. The scale is constantly teetering back and forth between the two. Personally, I’ve got a little grudge with nVidia since their driver messed up my computer’s settings, so I prefer ATI since I never had that problem with them. Anyway, I agree with Kman.
EDIT: And holy $*&@! those are MINIMUM specs! My computer barely meets the minimum!
Not bad for a 3 year old.
