i5-2400 >>>>>>>>>>>>>>>>>>>>>>>>>> A8-3850
I know you got the A8-3870K, but even with some overclocking, I can't imagine it being all that much better. Seriously, the gap is so wide that OCing won't get you Intel-level performance. (I am a bit of an AMD fanboy, and it sucks having to say something like that. T_T)
Undoubtedly a better performer, but also $50 more expensive. Also, it's best combo discount on a mobo is $18, compared to the $40 discount received for the 3780K + UD4H. If you split the discount then the 3780K was conceivably $60 cheaper since the aforementioned motherboard was significantly out of my budget. Even with the cheapest H61 motherboard ($50-ish) it would have been more expensive and would just be another part to upgrade, furthering expenses.
