First off Wheeler if you wanted to get a PCI-EX you would need a Motherboard that could supprot it meaning you would have to buy anotherone. PCI-EX is not cheap, they are top of the line video cards, most of the time. You can only go with "PCI" and ill search, for one, but you can also the more money the more better, trial and error always will set you ahead from someone that just gets everything thrown at them, but for sure you are doing the right thing by asking. And BY no means am i saying dont ask, compare the cards you want see which one has more options, more res anything you want its cool. Just post we will tell you.
