Hello,
I have an eMachines ET1352g and wanted to get dual monitors but apparently I need a new graphics card.

Does anyone know what kind of graphics card I can get without having to also get a new power supply?

Oh and the current graphics device is Nvidia geforce 6150se nforce 430

 

[AMD Radeon]

if you have dual head graphic on your mobo, usually DVI + VGA
you dont need any graphic card put your 2 cables monitor on them

if not, get a cheap nvidia GT 630 instead dont get AMD card because your mobo use Nvidia geforce 6150se nforce

to avoid internal graphic driver conflict

gt 630 is mere 50w
