Two graphics cards from the same manufacturer and two monitors.

Good day, I have a problem
PC configuration
CPU - QuadCore AMD A8-5600K, 3919 MHz (39 x 100) RAM 8144 MB (DDR3-1333 DDR3 SDRAM) Video: AMD Radeon R9 270 2048MB DDR5 (256bit) (900/5600)
Connected to the system two monitors on the GPU of the Radeon and when installing the latest driver from the manufacturer of the monitor 2 which is connected to the integrated graphics card stops working. I understand that new drivers do not support old graphics card and refuses to work? Under the old video card I mean a graphics card built into the processor. To me it is not difficult to sit on the old drivers, but yesterday I wanted to play Battle 1 new and game told me: baby bro, put new wood and then I'll be on for these old If it is possible, then tell me what can be done so that the new drivers worked for two graphics cards and two monitors actually? I desperately need is two monitors and I can't temporarily abandon one.
