1. Budget & Location
I live in brazil, I want to spend 2000 Reais on memory, motherboard, cpu and case, I already have psu HD's and SSD,
2. Aim
I want to play VR(HTC vive), so in a few months, after I buy CPU mobo memory and case, I will buy a gtx 1080 or 1070, and for monitors if I get the 1070 I will buy a 1080p 21:9, if it is the 1080 I will get a 4k monitor to play at 4k, and stream from time to time.
3. Monitors
I have a 1080p 16:9 and a 720p, but to play I will end up using only the ones I said before
5. Why are you upgrading?
I use a amd athlon II 640 and a gtx650TI now, and wanna play VR in a year, and depending on prices of the cards(if I get a good discount on the gtx 1080) I want to play on 4k(no aa)
The thing is, here in brazil skylake processors and haswell cost almost the same, but the motherboards for haswell are way cheaper and I wouldn't have to memory, since it is DD3, but I am afraid I would not have much of a space to upgrade the pc on the future if I get a Haswell.
I am thinking about the i7 4790 for haswell, and if I stretch a bit my budget I could get a 6600k on a z170 chipset, but for now I wouldn't overclock cause I have no money to buy a good cooler for i but I would like to get a 6500t, both with 8Gb of ram.
ps: gtx 1060 havent launched here yet, and 970 are way cheaper than a rx 480, and gtx 980 ti, the cheapest, cost around the same as a 1070
edit: I forgot to mention, almost everything is refurbished, cause buying brand new things here end up costing like 1.5x the price of the refurbished, and here we have big shops that sell only refurbished components, and they have some kind of warranty for every piece.
