My first x99 build - it had its challenges but has been an overall successful and satisfying project.
I started this design with the case choice - the Phanteks Primo. Truly a monster case - If you are interested in doing a custom loop, or just want a behemoth, I highly suggest it. The unique isolated power supply setup is lovely and the case oozes quality and potential cable management.
To be honest, I am an MSI fanboy haha. When I first heard about the X99 XPower, I was pretty much set on it. Stylish, feature packed, and high quality. Love the fact that there are two RJ45 jacks, a direct USB slot, two USB3 headers, and enough OC features to keep anyone busy.
COMPLAINT/WARNING: The first PCI slot is dangerously close to the DIMM slots and the "Xpower" heatsink/LED. I had an MSI GTX 980 in there without any troubles, but when I switched to SLI GTX 970 Golden Edition, I had a big issue. The backplate interfered with the DIMM "latches" and made it unable to be properly seated. I had to cut the tips off of all 8 slots to make it work.
CPU: i7 - 5820k 3.3 GHz 3.6 boost - 15 MB L3 Cache - 28 PCI Lanes While overall it has been nice to have the 6 cores, the processor feels slower than my DC 4790k in 80% of my use (which is understandable due to the significantly lower clock speed). It handles Photoshop and Illustrator and doesn't really bog down. The slower startup is somewhat annoying- Bios time 18-22 seconds vs 4790k bios of 4-7 seconds. Obviously different setups, services, etc... but worth mentioning.
RAM: Dominator Platinums 4x4GB 2666MHz with a 15 Cas Latency - no comments or complaints haha. Corsair knows how to make some sticks.
CPU Cooler: Kraken X61 - I first used this cooler on my Z97 build. I MUCH MUCH MUCH prefer it over Corsair's H series. CAM is a young, but promising software. NZXT has already came out with 4 major updates since I have had a Kraken - proof that they are invested in improving the product. Bonus, it looks amazing.
GPU: Originally had an MSI 980 Gaming. Really enjoyed the card and it had significant rendering power advantages over my Gigabyte G1 970. However, MSI released the special edition 970s and I couldn't resist. I have been wanting to do an SLI build for a while. I will update after a good week or so.
SSD: The Intel 730's hold up during my adobe file cycling - pretty fast and can handle a lot of operations. Looking to get the Phoenix Blade PCI 480GB drive soon.... 2000 MB/s!!!!
