aviax :
The games im playing are usually very cpu intensive, i play alot of the arma series (ArmA 2 Dayz Arma 3) with alot of mods, and im tired of playing games on there lowest settings, thanks for your help, hopefully there isnt that big of a difference so i think i'll go with the 5800!
If there is an issue, the unlocked multiplier is your friend, you can push the CPU a bit higher if need be, just keep an eye on temperature and keep the voltage as close to stock as possible, if you do push it higher.
If you decide the FM2 socket isn't fast enough, you always have the FX 6300 & FX8320/50 available on the AM3+ socket, which should be more then fast enough, but will require a new board & CPU.
