While this may be my first serious computer build, I strongly feel that I made very few mistakes with this one. Working reliably for over six months now, I am very satisfied with the system I have put together. I still have yet to get a nice CPU cooler, which I plan to get a Corsair H110 280mm Cooler, but other than that, I strongly recommend this build to anyone wanting a serious gaming PC, but not wanting to spend crazy amounts of cash for the crazy 8-core CPUs and the 4 way SLI graphics setups.
Here's a brief part breakdown.
CPU: I nabbed the 4790K for a meager 10$ off at the time. I suppose I shouldn't complain though, popular CPUs don't go on sale very often. This is a very nice, popular CPU for gamers, and for a reason.
Motherboard: This was a great buy, I planned on buying a separate wireless card and RAM, but this little guy came with both! I got it packaged for free with the G.Skill RAM. It's also a pretty solid Motherboard, optimized for overclocking and longevity.
RAM: Pretty standard, popular, and most importantly, free RAM.
Storage: The black 1TB WD hard drive was on sale for 75$, and for an extra 10ish dollars from the blue version, I just figured I'd nab it. So far it's been a very solid drive, though I always recommend SSDs for serious gaming. The 110$ OCZ Vertex was a great deal for a middle end 240 GB SSD, and it has definitely served me well thus far.
Video Card: At the time I bought this card, AMD was offering a great deal packaged with their newer cards to where any buyer would get a few, rather nice games. Nabbing Star Citizen, Tomb Raider, and some other decent third game (Might've been Just Cause 22) was a nice bonus to an already pretty solid card. However, without that bonus, I very well may have bought a nice Nvidea card. While the R9 290 is not a bad card, there are a couple of games in which I can not turn the graphics all the way up without some lag. However, Star Citizen is not yet one of them, and therefore, I can give some kudos to this card.
Case: An extremely well-built case, this one shined out to me from the start. This case definitely has it all, longevity, great aesthetics, lots of room for cable management, and amazing airflow (HAF, or High airflow is not a joke with this case).
Power Supply: This was one of the best deals I got on this PC. At 95$ on sale, this power supply is not only extremely high quality, but also fairly cheap. Even now on Newegg, I think you could get this unit for a whopping 130$. However, for anyone looking to cut a little bit of cost on their PC, I would get something cheaper, definitely not a 660W platinum rated power supply.
Optical Drive: This is not really worth noting, it was cheap, and it plays CDs and DVDs.
Monitors: 2 or more monitors are now a must-have for me, and these do the job optimally. At 140ish USD, this 21.5 inch 1080p IPS LED backlit monitor is a nice buy. I didn't have a huge budget for monitors this go around, but there are definitely larger options for those that do.
Keyboard: An amazingly beautiful mechanical keyboard, this was a great buy for me. Not everyone is able or willing to dish out 170$ for a RGB mechanical keyboard, but for me, this was definitely worth the extra cash. Even if I didn't have the funds for this particular keyboard, in my opinion, a 50$ mechanical keyboard is a million times better than any membrane keyboard out there.
Mouse: Anyone who uses wireless desktop mouses for any reason, this mouse is for you. I've never enjoyed using wired mouses for any reason, and at 25$ this wireless mouse is both solid, and inexpensive.
Custom parts: Unfortunately, the PX21s were discontinued, but this is definitely one of the most enjoyable headsets i've used. The UPS was a must-have for me, as an SSD and power outages are not good friends, and where I live, the combo is a definite possibility.
Any comments, praises, or criticisms are gladly welcomed.(Keep in mind this PC is over 5 months old!)
