I'm also toying with a Microcenter "upgrade". This from my Q9300 C2Q chips, overclocked from 2.5 to 3.0.
I looked at the AT CPU bench results, between a Q9650 (3.0Ghz C2Q) and an i3-2100 SB chip. For some heavy multitasking benches, and even a few gaming benchmarks, the Q9650 pulls ahead.

So this would likely be nothing more than a sidegrade for me, especially since I do DC, where a quad-core can be fully utilized. But it would get me to a more updated platform.
However, I want to keep my IDE and floppy ports. So there's two options for me:

Fatal1ty P67 Performance Socket 1155 P67 ATX Intel Motherboard
$100

Fatal1ty Z68 Professional Gen3 Socket 1155 Z68 ATX Intel Motherboard
$260
The Z68 Pro is an all-singing, all-dancing, platform. Three PCI-E x16 physical slots (x8/x8/x4), is "Gen3" ready, but is SO DAMN EXPENSIVE.
I once bought some expensive X48 mobos, and then six months later, Gigabyte released their EP45-UD3R/UD3P boards which were as good or better overclockers, and half the price. So I've gotten burned before buying high-end motherboards.
I guess I could definately do with the P67 Performance board, but it's OOS. I hope it gets restocked. (Is Intel still making P67 chipsets even?)
If it doesn't get re-stocked, I'll probably just choose this board:

Z68 Pro3-M Socket 1155 Z68 mATX Intel Motherboard
$110
Micro-ATX, but WTH, if I'm only going to use one graphics card, might as well. It's cheap enough. ($60 after promo discount)
The Z68 would be nice. I currently own several 30GB OCZ Agility SSDs. I could use one for SSD caching if I get a Z68 board, combined with a 1TB Seagate 7200.12.
If I got the P67 Performance board, then I'd probably just run the OS off of the SSD, and I might dump the 30GB and buy a 60/64 or 120/128GB SSD instead, with the objective to move to a SATA 6Gb/s SSD, instead of just SATA2.
Edit: The other possibility, is to go all-out with ONE of my rigs, and keep that as my gaming rig, and sell off my other two Q9300 rigs (with some low-budget video card in them). In that case, I would get the Z68 Pro, and keep my two GTX460 1GB cards and run them in SLI, and get a 2500K and OC to 4.5 (or whatever I can reasonably get to, at as safe a voltage as possible).
