Go for R9 280,
They are more expensive, but it's definitely worth it by time.
how come? 2X less power for the same money They are more expensive, but it's definitely worth it by time.

I mine with both 5850's and 5870's and think they're definitely a great choice. For bang vs. buck they're probably the best choice. I am running 36 of them myself.
I did buy 15x 7970's a short while ago and just had problem after problem with them and ended up returning them to the manufacturer for a refund.
One thing to consider is that even identical cards may yield different results in terms of hash rates and temperatures. Some of my 5870's hash at 440kh/s at around 60 degrees, while others run at 80 degrees hashing at 380kh/s.
Same goes for the 5850's. A few of them I have to downclock to 280kh/s to keep temps around 80 degrees while others run close to 400kh/s and I can't get them to run above 60 degrees no matter how hard I push them.
You would think cards coming off the same assembly line would be identical to each other in terms of operation, but that's just not the case. I guess as long as the manufacturer feels they meet a certain benchmark, they're ok to go.
Either way, go for it. At 100 bucks a piece, that's not a bad deal. I get mine new directly from a manufacturer in China and pay only slightly more than that.

Want to build my first mining rig. however I want to spend as less as possible.
seems like used second-hand 5850 cards are giving the best value for money now?
Cost about $100/each and gets 370kh/s when overclocked, or $300 for 1100kh/s
The r9 280x costs here $400 each and gets 750 kh/s or $590 for the same 1100kh/s so about 2X more expensive for same power!
and you can use 3X 5850 cards on a 750w power supply which is like $40 instead of $200 which you would need for the r9 280x
Anyone has find anything better for money/value?
