After a long deliberation & without knowing much about specifications, out of a hunch I propose to upgrade my box with these below, & braking my long tradition with AMD I went Intel for a change.
Besides daily use of my PC the only game I use is FS9 (not fsx) & the only reason for upgrading is to improve as much as possible my fs9.
I hope an expert will advise as to whether all these components are compatible with each other, or did I choose the wrong bits for that Mobo?.
