Anyways, if I buy a z77 board, my i5 2500k I currently have in my z68 board will work fine right? Does the z77 support lga2011 or something too?
The Z77 is a chipset and it still works with socket 1155, just like P67 and Z68. All Sandy Bridge CPUs, including you 2500K that work with the latter work with the former and Ivy Bridge 22 nm CPUs will also work with P67 or Z68 based motherboards with a BIOS update.
LGA 2011 is the enthusiast socket, and currently is paired with the X79 chipset, maybe later in the year there will be a newer chipset which includes native USB 3.0 support, just like Z77.
1155 = mainstream socket, P67, Z68 and now Z77 and its derivatives, maxes out at quad cores, either 32 nm Sandy Bridge or 22 nm Ivy Bridge.
2011 = enthusiast socket, where you have six core CPUs and later eventually even eight core CPUs. Can use either 32 nm Sandy Bridge-E or the future 22nm Ivy Bridge-E.
As to you upgrading to a Z77 motherboard, there is no reason for you to do so. It's more logical to upgrade your CPU in case you want something a little better like a Core i7 3770K, which has HT, a bit more cache and PCIe 3.0. Check to see if your motherboard supports PCIe 3.0 with a BIOS update.Edited by tpi2007 - 4/10/12 at 5:27pm
