Okay I have a fairly old pc and I want to upgrade the RAM and video card to meet the requirements for World of Warcraft and Counter Strike and other games that I am unable to play because of my specs.

I was wondering if any brand of ram and video card would work because this is my first time upgrading a PC and I dont want to waste money on something that wont work.

I also took a look inside and saw 2 PCI slots free and 1 ram slot and 1 AGP slot free. Also when buying a video card which would be a better solution PCI or a AGP card? Now I have no Idea how to put them in when I buy them if someone could shed some light on that.

If any additional info is needed please tell me and thank you for your time.
