Thank you guys, i'll pick the Ti tomorrow, i hope that this will be still available. Do you know a good mobo under 100 that i can use? I had find Asrock H81 Pro BTC R2.0 but unfortunately it is now sold out everywhere
For a single card? Pretty much any modern mobo will work. If you want to future proof, get one with 6-8 pcie slots minimum.
For my builds I went cheap: a GIGABYTE GA-H110-D3A and a BIOSTAR TB250-BTC+, both with cheap Celeron CPUs and single 4gb sticks of RAM. Does the damage just fine, at least using Ethos. Boot times are a little slow but once everything starts chugging away you can't tell the difference and the power consumption is good and low...
