Recently, I replaced my ATI Raedon 5570 HD 1gig DDR3 with an ATI Raedon 6450 HD 2gig DDR3 because my 5570 decided that it was going to melt it's own cooling fan off.
My issue is that even though I upgraded my GPU, my graphics seem to actually be worse! To try and fix this, I uninstalled and reinstalled my ATI Drivers, but that didn't seem to make a difference for Single or Multiplayer games.
My power supply is good for the new card, so that isn't the issue. My Processor is an AMD Athlon II X4 640 Processor with 3.00GHz. My antivirus (Avast!) shows no viruses either.
I'm at a bit of a loss here. Any ideas?
