Graphics Upgrade

Can I upgrade the graphics card in my Toshiba Satellite 2435?

My Toshiba Satellite 2435 has a 32MB NVIDIA GeForce4 420 Go graphics card, which is way underpowered compared with the rest of the system. Can I upgrade the card? If so, what card would you recommend? I'm thinking 128MB would work well with the 2.4GHz Pentium 4.

1. Did some more research, I didnt realize Nvidia was making integrated graphics for laptops..... This is an onboard chip, not a graphics card, sorry bout my previous response.....
2. You cannot upgrade the graphics card. NVIDIA GeForce4 420 Go graphics controller; 32MB external DDR video memory http://www.csd.toshiba.com/cgi-bin/tais/su/su_sc_outFrm.jsp?moid=321480&ct=DS&soid=638173&BV_SessionID=@@@@0283517529.1173067573@@@@&BV_EngineID=ccciaddkflekefecgfkceghdgngdgmm.0
