win7 is practically plug and play, just have to re install drivers, cant guarantee it working with you switching motherboard though, i'd recommend an fx8320 and a gtx770 because like hell you willl see a difference in gaming and multitasking with an i5 unless you run benchmarks and then it depends on the benchmarks you use. plus its cheaper , you will see a better fps increase with a 8320 and a 770 rather than a i5 and a 760, even if it takes more time buying the better graphics card then upgrading the cpu, if you intend on getting a gtx760 id stay with the fx4100 and overclock the cpu
