Hi guys. I built my PC in January 2011. I bought the Phenom II x6 1090t BE. I had bought an ATI Radeon 5870 the previous year so I thought I would just keep it for a little longer. I have been thinking for a while now to upgrade my 5870 to a 7970 since it is now getting old. But recently I have come to a slight realization that a hexacore CPU may not be the best for a gaming rig. So do you guys think my CPU should be changed to an intel i5/i7 quad core or amd quad core instead? Or keep my CPU the way it is and just upgrade my GPU. So what do you guys think? All thoughts and opinions are welcome and much appreciated.
