CPU mining is done. GPU mining is still profitable though, for now.

I would wait until the product is proven though, and then use an online mining calculator to estimate how long your break even ROI would be. That requires knowing your electricity costs and making some other assumptions ..

Calculating break ROI on a future product requires knowing your electricity costs, but claiming that GPU mining is still profitable doesn't? Roll Eyes

My GPUs are offline a couple of months already for a reason, although with the recent rise in price it gets back closer to break-even, yet still no profit in sight and with first ASICs being shipped probably won't be profitable ever again.
It might still be profitable for you, but without knowing electricity costs for OP you can't tell if it would be for him too. But even if it would be, it's doubtful to get back the initial investment for GPUs.

But besides the requirement to know about power costs there's a lot more one needs to know to give advice about what the best way is, for example when you want to start, or how much money you want to invest, if you want to do it for fun, or for profit,....

Probably best to not mine at all (at least for now, wait for ASICs to "be available") and look for other ways to get some coins.
