ok i wanted to upgrade my old FX5500 to 7600 gs but it seems that's better to keep my FX5500 and buy an oc'ed 4870.
i'm planning to :
asus p6t deluxe
3gb crossair 1333 cl9
connect 3d twin acclero 4870
by now core2 quads better or corei7 and put some more money on vga
to sum this all up...you could play it but not very well nor enjoyably
just wait till ur future system
