That's a clean setup, looks good!

I didn't have another GPU water block before as I ran it on air only prior.  But my GPU temps are pretty good.  While gaming my gpu gets to around 100f at max.  My ambient is around mid 80s to mid 90s.  I really like the gpu block, it was worth it to me.  If you didn't buy a block yet, I would strongly consider getting the Optimus.  It was pretty much pain-free as could be as long as the $400 price tag is okay.  But when you think about it, the materials they use are really good and the back place with that huge thermal pad is included in the price.  The only knock on it that I can think of is there is no RGB.  But that's a personal thing and non-performance issue.  The design of the block is really good and it was easy to install.  The hardest part was removing the air cooler from the stock card.  After that it was cake.  
 
I did purchase the EK velocity and magnitude blocks for the CPU.  I lucked out in a way when I ordered the magnitude it was missing parts so I returned it.  The magnitude block was almost double the price if the Optimus CPU block and they were very similar.  I'd give the edge to the Optimus due to the way the materials are machined like the threads and the materials used seem to be just a little better than the magnitude.  But again, the magnitude was almost double the cost and the velocity doesn't even compare in looks and feel.  
 
I did a lot of homework on what GPU block to get, and in the end I'm glad I went with Optimus.  When my name gets called for the kingpin, I'm going to be getting the Optimus block for that one as well once they release it.  
 
I ordered a AMD 5950 last week so once it comes in and I replace my 5800x cpu I will be taking new pictures of my setup for posting.  I also plan on changing out my fans to something with a little more show rgb.  I'm going to try and get the new AL120s from Lian Li to replace my SL120s.  They should provide a little more RGB with a little more air flow as well.
