I'm planning to buy a graphic card for a gaming PC but I never actually assembled a PC before. I'm confused with these PCI slots.. How will I know where to insert a graphic card? Will it be on a PCI slot? X1? x16? Refer to these links for example: (Please add "www" on the links, the forum doesn't allow me yet to post links) Motherboard: tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4694158&Sku=E145-2059 Graphic Card: tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4369731&Sku=E145-0264 Where in the specs in the graphic card can I know where to insert it in the MOBO? Lastly, the graphic card says in it. Multi-GPU Support: 3-Way SLI Does this mean I can insert 3 graphic cards of the same type in this MOBO? Is it advisable to have multiple GPUs? Is it worth the money? Thanks!
