Ok, so I'm almost done upgrading my computer, all I need now is a graphic card. Like many other Dell users, I've been slapped in the face and only have 3 PCI slots. No PCI-E or AGP =[. After some research I'm deciding on the Diamond X1550: http://www.amazon.com/Diamond-Stealth-X1550PRO-Video-Card/dp/B000N9B8D6 Newegg just stopped selling PCI cards =/ My question is: Will it fit? I've read some things about form factors and such, but I have no idea how to tell if it will fit or not. My computer is: Dell Dimension 3000 Intel [R] Pentium[R] 4 CPU 2.80Ghz 2.79Ghz, 2.00 GB of RAM Last week I bought a 470w PSU, peaks at 520, and it fits and works fine. Also, the reason i'm upgrading is for gaming, and I know I won't be able to run the latest and best games, I should be able to run some newish games in low settings, right?? Can this thing handle Vampires:The Masquerades? or is there no hope?
