I am going to run this system on a 1080p IPS monitor.
I mostly game, web browsing, lots of word documents and dvd playback.

Just wondering which would be better overall?

P.S the prices for these builds are exactly the same price: $1993.20 USD

How does the Sapphire Radeon HD7950 OC 3GB compare with the Geforce 670?
I would get the 7950 build because the intel 520 as a boot drive would be beneficial overall.

I would start with the top build, then cut back on the "extreme performance cooler" and maybe somewhere else too in order to get a larger boot drive. Unless you are planning for a second graphic card, you dont really need a 750w PSU.

Windows and your default software by its self will max out 60gb -- if you want any programs on the drive it needs to be 120 or above. Also with SSD prices dropping you can get 120gb for $100 pretty regularly.

Edit: Just preference, but I like my Asus mobo. It will likely be easier to use than the Gigabyte.
