2) Depending on your PSU, if it is 450w and above with atleast 28a on the 12v rail, then you are fine.

I don't really know what's in my computer (because I bought it with all the parts installed), but I'm going to open my computer tomorrow to check it.

I'm just wonderingwhat it shouldsay on my PSU. I willprobably see how many watts it is, but I don't understand the rest of what you wrote.

I currently have an Acer M5500 with a GeForce 8600GT. I would like to buy and install a 8800GT, but I still have several questions.

- My computer has Vista Premium preïnstalled and I am wondering wether Vista will accept a new grphics card or not.

- Will I have to change my Power Supply Unit?

- Will a PCIe2.0 card fit in my computer, because I think I have aPCI card.
