Plus they are great for plenty of other games. I helped spec dozens of builds on various forums(and in real life too),and the FX6300 has decent performance when compared to Intel CPUs in many games.
The people bitching and moaning about how slow an FX6300 is,are those who have little or no experience of using sub £110 CPUs in any meaningful way. I have used the whole gamut of them from recent Core i3,FM2 Athlon II X4 and the FX63** series CPUs. Heck,I have a Xeon E3 myself,but I can acknowledge the makings of a good budget CPU.
The more games they can do well in the better for all of us. We should be having low end £110 to £120 quad cores from Intel now,not a reheated Core i3 which cannot be overclocked.
Heck,look in general hardware,plenty of builds with the FX6300 are specced by loads of members(people such as Stulid and the like),if the budget does not allow for a £150 CPU.
