Alright, I have an eMachines T5234 and I was thinking about getting a new graphics card. What I was wondering is if the Radeon HD 2400 would be compatable with it. Also, what other grapics cards might be compatable with this computer, that are also somewhat affordable? As far as I can tell I have an open PCI-e slot, however I am not sure if it is just PCI-e or PCI-e x16, which most cards seem to be. Some sites say that this computer has a PCI-e x16, but others don't mention it. Help please?
