okay i'll bite. My dream PC would be a nicer more expensive version of what I have now. Two months ago I built a system that incorporates :
i5 6500 3.20 Ghz / 3.6 Turbo
Gtx 1060 6GB
8GB 2133Mhz Memory
Windows 10 Home 64
Samsung Evo 250 GB Solid State Drive
Western Digital Blue 1 TB 7200 rpm Hard Disk
Fractal Design white chassis (Purchased one additional Fan for a total of x3 140mm Fractal design Fans)
Asus z170 E Motherboard
EVGA 750 w Gold Certified Modular Power Supply.
If the sky was the limit I would of purchased a 2 TB Western Digital Blue Hard Disk, More Memory and higher end, i7 6700, and GTX 1080. I have no desire to overclock, use liquid cooling, SLI and that being the case even my current mainboard is overkill so Id also pass on X99.
In my new build I already possessed windows, the ssd so I saved money there that is all I could re use from my old system. While waiting for my 1060 to arrive the last component I ordered(I had the system built without it) I used my R7 370 I had purchased in 2015.
