Hello, I recently purchased the 7870 Le for my pre built cyberpower pc that i bought back in november, this computer from the get-go has had poor results, despite high benchmarks, strong components, and reviews. I have never really been happy with this purchase, and it was pretty expensive, about 850 dollars for the pc, 100 for an RMA gfx card, and I recently spent 250 on this gfx card. Im still getting very poor performance graphically in games, despite using catalyst control center and also in-game settings, I'm completely just distraught and have no idea how I could spend so much money and have such poor results, please help.
