Put this rig together about a week ago for gaming and other fun stuff. Assembly was a breeze (3 hours for a first timer). My only issue while building was the double 8-pin PCI-E cable, and that was just about looks. My plan for this build was to get quality parts and have a good upgrade path. I could've cheaped out on the case, mobo, and SSD, but I wanted a very solid system without breaking the bank.
CPU- runs even better than I expected, definitely a recommendation to anyone building on a budget
CPU Cooler- Had issues mounting (couldn't figure out the bracket), but it is very effective and runs super quiet
Mobo- Great BIOS, easy settings, and that matte black PCB is just plain beautiful
RAM- Nothing fancy, just cheap and reliable
SSD- No problems at all, highly reviewed, blazing fast. Enough said.
HDD- Old recycled HDD, meh.
GPU- Oh man, this thing is a BEAST. Everything runs perfectly at max over 100-300fps (I'm playing TF2, Warframe, LoL, Trackmania, and War Thunder)
WIFI Adapter- Don't buy this. Spotty drivers and overall bad performance make this my least favorite part on the list.
Case- So simple and easy to set up, gorgeous, and very expandable. Not the smallest, but I don't really care.
PSU- Not a big fan of all the cables and sleeving, but I still would recommend this one.
OS- Booted up from the HDD, and Windows 8 Pro just started up! I was insanely happy. Totally satisfied. Mouse/Keyboard- I'll upgrade these soon, not terrible but not great.
I plan to grab an i5-4670k and another GTX 760 in the future. I'm also buying a 1TB Caviar Blue HDD and a new mouse/keyboard soon.
Total for the build at the time was about $850 (USD).
