The Intel G3258 is an Intel Pentium Processor made as an anniversary edition that allowed "low-end" users to Overclock. For the price it comes with and the overclock-ability of this little beast it's a pure win (if you so do decide to overclock it). The heat deduced from this Haswell architecture CPU is so small that even a stock cooler should be able to give it up a few notches on the VCore and Multipliers without causing any severe damage to the processor. And better yet, with some of todays B85 motherboards you are actually able to unlock "the power of overclocking", which in past was only possible with higher end motherboards such as the Z versions.
For a simple botting machine, it should suit you well. But there is one thing you should take note of: The CPU is only a dual core and it does NOT support hyper-threading (one core = one thread. hyper-threading allows for twice the threads of those of your cores, though it is only virtual/logical and not physical like a core itself, it still provides the processor with some extra Oomph!), so running multiple bots at the same time with this processor is probably unlikely.
