This holiday season I am thinking of upgrading my venerable i5-2500k to an i7-3770k. I am currently using an AsRock Extreme 3 Gen3 Z68 LGA1155 motherboard. Based on my limited research, the 3770k should fit in my existing LGA1155 socket. However, I am curios if using this new Ivy Bridge architecture will require a BIOS update to my motherboard. I've seen that if you are using a Z68 motherboard, I won't have to mess with the BIOS in which case I should just be able to remove my old processor/HS and plop in the new one.
Can anyone attest to the fact that Z68 motherboards do not require BIOS changes?
Assuming the Asus GPU for $200 is bought, what are some good coolers in the $50 range? I've heard a lot of good stuff about the Hyper 212. Is that still a good aftermarket cooler? Sorry for all these questions, I've been out of the PC scene for a little bit and so much new stuff has come about during my "absence".
