What do I think about the parts?
I choose the i5 4690k for the cpu. It offers great performance with a great price. I actually got it for only $199 at microcenteer. The Asus z97-A is a great motherboard for the money and with all the features it has you can't really go wrong. It doesn't come with wifi or Bluetooth so you might want to pick up a dongle for that. I got Bluetooth for only $5. Corsair vengeance 8gb of ram great for gaming and you can't really buy "bad" ram. The WD caviar blue isn't the fastest storage out there but it is quite reliable. The 120gb of Kingston SSD makes up for the lack of speed on the caviar blue in fact this Ssd is one of the fastest ones I've seen. The Sapphire vapor-x 280x 3gb video card is one of amd's high end budget models, it's a little bit underpowered but for the performance it's the one to get. Plus my friend had the one I am using now and was willing to give it to me, and he is going to give me another in a few weeks so I can use both which will help the machine overclock. The corsair spec 02 red full atx is a great case which they sell at microcenteer for about $39.99. Great cable management, great price, reliable, you really can't go wrong with corsair products. The psu is the corsair rm850, fully modular, but the cables are thick and can get kind of annoying if you have limited cable management room. I know you may think why do I need a 850 watt $160 psu for a pc that only uses less than 450 watts? You don't. I just got a really lucky deal at microcenteer where they had the box mislabeled so I only payed $54. Why not more power for less cost?
What do I use it for?
I use the computer for some gaming and experience 0 lag whatsoever. I also type a lot of documents for school and like to have multiple tabs open at once. Still not a bit of lag.
What do I like best about it?
Definitely the speed. I was used to working on an Acer laptop with the pretty much first ever pentium and first time I used this pc I was blown away with how fast this thing runs. My old computer booted in a few minutes this one only takes 5.8 seconds! A huge difference.
What is the worst part about it?
I don't have to many complaints except the case. It is a bit tricky to take the see through panel off. Otherwise nothing.
Where did you get the parts?
Microcenteer is the place to go. The have the best prices around plus they price match most major retailers.
Let me know if you think i could upgrade this build in any way!
