I have a Dell 2350 with a Pent 4 1.8ghz and 512MB of RAM. I'm looking into getting a new video card. The one that came with the computer is a 64MB Intel (?) video card. The 2350 doesn't have AGP inputs so I'm looking into getting a PCI card- 128MB perhaps. Is it worth the $100+? Will it really improve gameplay? Will graphics improve? Am I wasting my time? If it is worth it, which ones are best? Thanks!
