Hi, I know this might be noobish question, but I would like to purchase a new graphic card and I wonder if it is compatible with my motherboard. I mean Im sort of confused with this new PCI-E 2.1 thing. In overview of my motherboard ( http://www.silentpcreview.com/article855-page1.html ) it is stated that it has: "1 x PCIe x16 (Support PCIe 2.0 / 1.0 Architecture )" so it does support PCIe 2.0.. but what about this PCIe 2.1 ? I've read that it should be the same architecture shouldn't it ? My question is therefore simple, will it work together ? btw. the graphic card would be most probably: GIGABYTE VGA ATI Radeon HD 5850 1GB DDR5 thanks !
