Hello laides and gentlemen. I have two very important questions... 1. I have a piece of crap mother board with only PCI for my video card. I want a new one that supports my RAM CPU and a PCI-E slot. When i get my new motherboard and put it into my comp. Do i need to re-install Windows on my hardrive or will everything just work fine? 2. Right Now I have 1 gig ram 2.66 ghz CPU and most importantly: PCI 256 MB 128 bit NVIDIA GeFoce 5500 FX video card Will this be decent enough to play Call of Duty with no Lagg??
