AMD Radeon R9 270X 4GB vs R9 280 3GB?

Solution
R9 280 is better, look up some benchmarks, the 2Gb vs 4GB versions of 270X hardly make a difference, unless you plan to CFX in future. And 280 is better than 270X in every dept. 270X can't by itself use the 4GB VRAM provided to it, it's just not powerful enough.
