The point I was trying to make listing the parts was; you can get a decent specced PC that will out perform the PS4 right now for close to what most are guesstimating the PS4 will sell for on release day.
Yes I do think a 7870tahiti/660ti will be able to play games 1080p @ 30+fps on medium medium-low settings in 4-5 years. The same as my Clevo M570RU laptop with a 8800M gtx and dual core CPU (purchased in Dec 2007) can play most dx9 games medium to max -- a majority of games are still DX9, FYI.
