回複：請各位幫忙指點一下，想升級顯卡

1)you need to check if your main board have slot for new display card. (like AGP, PCI-e or PCI)
2)most of the display cards have 256M of memory that is good for 1680x1200
3)for games you can use Geforce chipset, for video and graphic - I prefer ATI chipset

hope the above could help
