Newegg was offering a free Crucial 8gb DDR3 1600 Cas9 module with an Asus Z77 motherboard so they suckered me into doing my upgrade 6mos. earlier than I had really planned. Pretty sure this is the route I'm going, just thought I'd put it up in case I've made a big oversight. Gone to a 3570K, 16gb of RAM (had to get a second matching stick!) Asus P8Z77V-LK The Seasonic 660w Platinum PSU 2tb Seagate Barracuda HDD (I have a cache drive, and I like only dealing with one volume for Steam and that) Putting it all in a Fractal Design R4 - The plan is to try and keep it as quiet as possible. OC is mostly an afterthrought. I might grab that new Swiftech AIW cooler to that end, though. My GTX570 carries over along with all the peripheral stuff. (anyone want an i5 750 system? It's going cheap! Just add an HD)
I have the same case. I can confirm its quiet enough for my home studio work (field recording mixing and mastering work and video edits) when paired with a closed loop cooler and my enermax fans.
