Switchable graphics nightmare

Hello, new here and was very impressed with previous help. Have what seems to be a ubiquitous problem but not clear there is any good fix, or if technically this is a hardware issue. Bought a gaming computer off ebay for a friend. Windows 8 Intel i5 Quad w/AMD R9 270x and the golf simulation install talks about going into "switchable graphics" option which apparently no longer exists on the newer cards in Catalyst. Have read a lot of posts but no clear solution that works for all. How to dedicate the GPU to run or ideally run these applications while the touchscreen monitor can just run of the integrated intel graphics on the ASUS H871-plus board? Amazing when you try to do someone a favor you can find yourself way over your head in a mess....
