Is the 360 for me?

[niksta2]

I have a PS3 and am interested in a 360 mostly for it's exclusives and markeplace content (which is supposedly amazing)

I am interested in online play but have very few friends that own a 360,thus making the online payments kind of pointless

as well, my PC has 1GB of RAM, an NVIDIA GeForce Go 7300 and Genuine Intel CPU T2400 @ 1.83 GHz, can somebody tell me if this is any good for 360 games that come to the PC?

thanks,
