Well they will all play current games at lower rez, but as far as being ready for anything coming up in the next say year or two, they will seriously underperform. The 7900 would be your best bet, but I don't think the E15 even has that as an option right now. Look at it this way, your current 9800 will spank a X1400, as it's not really a good card for gaming in general, none of those cards are except the 7900. The 7300 is comprable to the nivida 6200 series. In laptop gaming there aren't many options in the midrange budget right now.
