On a side note, the last of the parts for my new rig came in the mail! Woot! It's a 4670k, 500GB SSD, Dual GTX 660 beast! I can't wait to put it together later on today!
Oh, that should be a beast alright. I am running a single GTX 680 and have been hammered about going sli. Don't know what your last CPU was, but if it was a second Gen Sandy Bridge or earlier, you will notice the difference out of the box. I went from a 2600k to 4770k.
My last CPU was an AMD Phenom II X4 955 CPU. Just got the rig put together, posted, booted and installed windows 8 pro no problems. The Hydro H50 took the longest to install since I've never done a CPU water cooler but even that went pretty smoothly. Between cigarette breaks and searching the house for appropriate screws (man they really skimp on the screws in packages nowadays, lol) it took 4 hours to build and install windows. I'm actually on my old PC now and about to hook up the new one in my bedroom. I'll show you all some benchmarks and WEI and all that when I get it hooked up and after I install Windows 7 on my old rig for my Dad to use. Only thing that sucks is I thought the top case fan openings on the top of the Carbide 500R case were only 120mm and so I bought 2 Corsair 120mm fans for them. While installing them I saw I could have put 2 140mm fans in there and that would have definitely been preferable. Oh well, I can always slap a couple in at a later date. The two 120mm fans should be fine for now and I'm not doing any really aggressive overclocking. Might try to get my 4670k to 4.5GHZ and just leave it at that. I should be happy with that speed increase I'm sure. Is that still too aggressive of an overclock for a 4670k though? I know the 4770k's are getting 4.8GHZ in some instances.
