If it were me and it is not, I would take the lesser machine of the two. Reason one, I would never use 640GB of hard disk. Not in this life time. That leaves us with two processors. Both are close in speed. Too close to matter to me. Vid card, the card with the 512mb should run SH5 without issue. 4 gigs of RAM are just great so you are good there no matter what you buy. Toshiba is a good computer. My folks have one and they have not managed to blow it up. Lord knows they try.
