Im starting on my newest project which is constructing a home build version of the redharbringer cross desk. The last thing i need to pick out is the GPU configuration. I have a 600w psu right now that I think id need to switch out anyway. Should i go with the lesser option and get 2x r9 290s right now or get one gtx 970 right now and get another one later because i cant afford it right now. The desk sucked up a lot of my budget. I'm currently running duel 1080p monitors and i will add a third soon. Thanks and ill start a thread here with pics of the desk being constructed.
