I recently bought a XFX Radeon R9 280A-TDFD. The problem with this is that I feel that some of my graphics, compared to my last card the GT 630, are not living up to the 630. I don't know what the problem is but ut is quite annoying. My 630 PC was powered by a very old Intel (pretty sure it just said Intel Core). This is powered by an AMD FX-6300, which I understand isn't as powerful as Intel, but I know it's better than that one. If you can help me that would be great. Thank you.
