Is this build good for 1080p 60fps(updated)

That build should get 60fps in just about any modern or even near future game at 1080p on max settings, supposing it isn't horribly optimised.

I do have some suggestions however, considering you're spending the extra money on a z270 board, you should be buying the overclockable 7600k, rather than the locked 7600. Also, if you can fit it into your budget I would I highly recommend adding a 250gb SSD as your boot drive. It will improve the load times dramatically on the games you put on it, and your PC will boot much faster. If you cannot squeeze the SSD in, it might be worth it to switch to a 7500 and go for a motherboard that doesn't support overclocking, as a 7500 running at stock settings is plenty for 1080p modern games.

Hope I could help, have a great day.

First a few build comments:

1. The 3rd party cooler serves no purpose with a non K series processor

2. I never recommend "bleeding edge" purchases which is basically using 1st stepping MoBos and CPUs ... I feel much more comfy waiting till all the bugs and improved efficiency tweaks are in place which is not what you will get buying components that just dropped. We won't do any Z270 builds till late April / early May

3. There's quit a bit of a mismatch with a $200 Z series MoBo and non K series processor. Those features are available from competitors at much lower prices.

4. Look at this chart before picking ya storage options:

http://www.tomshardware.com/charts/hdd-charts-2013/-17-PCMark-7-Gaming,2915.html

SSHD = 9.76 MB/sec
WD Bllack = 6.34 MB/sec
WB Blue = 4.01 MB/sec

Windows Boot Times:

SSD = 15.6 secs
SSHD = 16.5 secs
WD Black = 21.8 secs

5. I'd use a Seasonic S12 or M12 620 for the PSU. (M is modular)

6. TPU lists the MSI 480 as the only 480 they had tested up until that point that actually was able to compete with the 1060. The **reference** 1060 had a 6 - 7% performance lead over the MSI 480 Gaming. Head to head, that would have been a 10% lead for the MSI Gaming X 1060 6Gb over the MSI Gaming X 480 when initially released.

That gap has since narrowed with AMDs latest drivers providing an average 2.1% jump across some 23 games tested.... no word on what nVidia driver improvements may be delivering.

The MSI 480 does however draw 75 watts more than the MSI 1060 which warrants a bigger PSU and an extra case fan. That comes with an associated increase in noise heat and power costs. Most importantly however, if you use MSI Afterburner, is that the 1060 has about double the overclocking headroom that the 480 does.

None of that matters tho if the card you choose doesn't perform better in the games **you** play. So to directly answer your question, you can start here and look at the 16 games in TPUs test suite:

You can add 15.1% fps from overclocking the MSI 1060 and 8.6% for the MSI 480

Finding test results for Skyrim with 100 mods is a bit of a chore as it's a rather old title and test sites tend to lean towards "plan vanilla" installs
