Getting my a new PC for my birthday and I need some advice. It will primarily be used for gaming at 1080p or 720p. I don't plan on doing any overclocking. The parts I can re-use are a 6870 gpu, 4gb ddr3-1333 ram, and a 500gb harddrive. No OS is required because I can get it free through my university, and will be using the 50$ assembly and testing from NCIX. I am also Canadian, so prices are a little rough.
The budget for the build is a strict 900$ including taxes (13% HST), 50$ assembly/testing, and S/H. Which gives an effective budget of 750$ CAN.
This leaves me with several options that I've looked into.
(all builds using the same 500W PSU / Case)
1. core-i3 6100 skylake build, z170 mobo, with 8gb ram, a 120gb SSD, and an r7 370 2gb. (~$754)
1.1. same as above, with 4gb ram, no ssd, and a r9 380. (~$772)
1.2. core-i3 6100, h170 mobo, 8gb ram, 120gb ssd, r9 380 2gb (~$769)
2. core-i5 6500 with 8gb ram, z170 mobo, 120gb SSD, and reuse my 6870 video card (~$704)
3. amd 8320, re-use my 4gb ddr3-133 ram, 120gb ssd, r9 380 2gb (~$720)
3.1. same as above but with additional 4gb ram (~$750)
I know the 370 is an upgrade over the 6870, but it's not too substantial of one. The 380 would be a substantial upgrade, but it's a stretch to get it into an i3-6100 build at this budget. I could save about 30$ on the skylake builds by getting a cheaper H170(~120$) motherboard instead of a z170(~$150).
Would greatly appreciate any input/thoughts.
