I had an old HP Pavillion dv6 laptop, which I spent around 6+ hours on each day. Used it for programming and some light games like Dota2, even managed to complete Bioshock Infinite when it came out on relatively decent settings. But it wasn't really enough for what I wanted, it couldn't play newer games and was just becoming a little inadequate. So I decided to spend a bit on a 'proper' PC build which would be easier to use and upgrade.
I spent a few weeks looking over parts and doing research with a friend for which parts would be best from a performance:price ratio and came across the final build you can see. The 4690k is a pretty nice CPU considering its price, the CPU cooler (although huge) is very effective and quite quiet and the 16GB RAM is more than enough for me. I went for 2400mhz RAM and not 1600mhz RAM as it was only £5 more expensive and I wanted to test to see if it would actually perform better at 1.6ghz or 2.4ghz due to its faster speed despite the processor only supporting 1.6ghz. You're probably thinking that a 500gb SSD is on the large size, and it is, but I wanted to put a few of my most played games on it. The 1tb WD Black is for file storage which I don't really need speed for, like videos, and big games. In the end I actually went with a Vapor-X, not a Tri-X as the one linked by pcpartpicker is actually overpriced and can be bought cheaper directly from Amazon and it runs very cool, even on max load the fan don't go above 40%. I was originally going to go for a Nvidia gtx 970 but when I discovered the 3.5gb VRAM issue, I decided to stay away from that card. The Corsair 400R cause was chosen as it's quite spacey, providing enough space for the huge 30cm gpu. Now, so far, the build only requires around a 500w psu. I instead went with a 1000w psu as I plan quite soon to buy another Vapor-X and the extra power is for that card.
Building it was surprisingly straight forwards. After watching a few YouTube videos it wasn't that difficult to put together, although it did take me several hours and I only got about 4h sleep that night. Everything fitted quite well, the most difficult thing being remembering to wire everything to the PSU and cable management. The case is pretty good for cable managing, and one of the side panels extends out, giving you room to put all of your cables out of the way so that it doesn't affect airflow.
Overall I'm pretty impressed, it's on a different level to my old laptop. It was definitely worth forking out for an SSD as the 850 pro really did live up to my expectations. Windows loads in the blink of an eye, around 3 seconds to the desktop from off on Windows 10. I've only played a few games on it so far, but I've not had a bad experience, Gta5 for example plays at a solid 60fps with 16x AA and highest settings. Would recommend the 290 Vapor-X.
