I am building my first rig and have recently finished purchasing all components except the monitor. I bought an XFX R9 280X card and have recently heard that this GPU will not be compatible with FreeSync monitors as it is GCN 1.0 and 1.1 (I don't know anything about these standards, btw.) is required for FreeSync. My question is, should I return the R9 280X GPU and get something that will be compatible with FreeSync (R9 290, etc.) or stick with what I have and forget about going FreeSync? I am a casual gamer and will mostly play WOW and maybe some FPS like BF4. If I do go with a compatible GPU, will I need a stronger PSU than the 550W that I purchased? Are there any other considerations? Also, is it worth the wait for these new monitors to come out? Sorry for the ton of questions and thanks for any advice.
