The PC is going to be used for Gaming, hopefully run BF4 when it arrives, and to render videos. When i say render videos i mean use programs such as Sony Vegas and Adobe After Effects.
Then I would almost suggest going with an i5 - if you want to run BF4 well, that's what you're going to need.

Ill get rid of the Liquid cooler, but im worried that if i place that EVO fan on, it will get in the way of the RAM heat-spreaders. Also does the EVO fan come with pre-applied thermal paste?
The EVO isn't that big - it won't have ANY problem with the RAM, and even if it did, you could turn it to face up if you so desired. As for thermal paste, it comes with a tube of it.

For the SSD, i read that you should always put the OS on a SSD. Is this true?
For the GPU, is the Club 3D Radeon HD 7870XT 2GB reliable? Its because ive never heard of that company
You don't have to put the OS on the SSD, but that's one of the things that'll make the biggest difference. I'd throw windows, my drivers, any applications like vegas, ect. on the SSD, along with any games that actually would get a benefit (ones with long loading screens that annoy you, such as MMOs.)
Then what I'd do is have a separate, small (No more than a couple GB) partition to use as a scratch drive - you move whatever video project you're working on to that, and then when you're done with it, just move it back to your data drive.
EDIT: As far as Club 3d goes, I'd avoid them - go with PowerColor or Sapphire, which both have models of the 7870XT.
