I was faced with a similar dilema, and choose to go the intel route. Best decision ever (actually that was proposing to my wife, but still).
The i5 is a beast for gaming. If you can afford, I recommend getting either i5 2500K or i5 3570K as the unlocked multipliers make it ridiculously to overclock to 4GHz and above on a $20 air cooler (Hyper 212 Plus).
We'll see if proposing is still the "best" decision in 10 years XD
jking, hope you don't have as stressful a marriage like 100% of them
