i have a feeling the xbox 360 version of mgs will have less detail than the ps 3 one

if I have the cash, I would really go for nvidia, but if i'm on a budget I would prefer ATI

I don't know what's all the fuss about halo...it is not actually as great as microsoft says it is, although it is not bad either..its just typical microsoft always hyping their products but it always falls short of what they say the product is going to be...there are a lot of fps that is better than halo..don't be blinded by microsoft's hype building...
