(-_-) you got 7600 go and you want to change it?
i only got 6200 go... lags like nobody's business...
anyway... as far as i know, the latest graphic card for laptop is GeForce Go 7950GTX
you sure you can upgrade the graphic card in your laptop? most laptop is not upgradeable specially the graphic card.
Even if you can its very illogical to do so, it would cost so much for so little gain in performance. Appreciate your 7600 man, its mid range graphics and should be more than enough. You might as well get a better laptop with better everything than just upgrade just the graphics card even if you could.
the latest is MN8600gt, you may need wait for some time, but if you can change the graphics card at will? old graphics for laptop should be integraged on notebook mainboard.
But I'm pretty sure, unlike desktops, laptops don't all follow a standard. Unless a better card can be found specifically for that laptop, it probably wouldn't fit.
