SLI EVGA 670 on MSI Z77A GD80 with network card and capture card?

Yes it should fit just fine. I think you are spending to much on some of the parts though but if you have it why not I guess.

I have a 2 Gigabyte GTX 670 2gb cards and they are only $379.00 I run them on 3x Asus 27" monitors in 5760x1080 and even then I do not need 4gb the 2gb cards have worked great on every game I have played even games that are setup for Eyefinity/Surround. The point is I do not think you need to spend the extra $100 plus for four gig cards.

You did not mention what your new rig is for but I think 32gb is way over kill for the ram. I have 16gig in mine but that is only because it was on a really good sale at Christmas when I got it other wise I would have put 8gig in.

If you have not got the CPU you might consider getting a i5 3570K. It is really as capable as the i7 you listed but cheaper. For gaming the i7 does not really help as most of them need HT turned off and HT is the main difference between a i5 and i7 plus $100 more.

As for the Corsair H100i it is a really good cooler I have it cooling my i5 3570K and it does a great job. My idle temps run about 27c and I have not gone any higher than 45c full load with this rig. I also run it in push pull although I had to mod my In Win GRone because the top, the plastic part, is to low to the case to allow the fans and allow the top to be snapped back on not a big deal it jest took a little modding.

With that hardware capture card even recoding live game footage should not impact the i5 3570K since the capture card will be doing most of the work itself.

Like I said I am not trying to tell you what to get or what to buy just suggestions from what I have learned since coming back to intel/Nvidia. I had been with AMD/ATI for a number of years mainly because I just could not afford to build a good intel/Nvidia gaming rig. But when I did my 2013 rig I already had a FX-8350 and Crossfire Sapphire HD 7970's so there was really no way to go up with AMD/ATI.

A friend of mine went and build a gaming rig with a i7 3770K and a GTX 670(4gb) and then found he was getting stuttering in games that I was not after trouble shooting his system we found out that it was because of Hyper Threading turning that off in the BIOS and it was gone. So he turned his i7 basically into a i5 with a $100 more price tag. Also after spending the extra money on the higher GTX 670(4gb) he did not have enough for SLI so games that would work on my system at 5760x1080 were having problems on his because of no SLI. But hey if you have the money get it and do not worry. It is just a suggestion and I mean no offense so please forgive me if I am out of line.

Sorry for the long post I did not realize how long it was until I posted it.
