I'm upgrading a 2010ish dell optiplex 560 to make it more gaming friendly. It currently has a core 2 quad 9550 clocked at 2.83 ghz and I was wondering if the pentium g3258 would make a big enough difference (it may be worse, I'm not sure) for it to be worth it for me to go out and buy a new mobo and the processor or would the 2 less cores hold it back (I will buy a new cooler to overclock if I get the pentium). What do you guys think
