Grab the R9-270X and enjoy better gaming. Even If you can't get the OC that boloking was able to get, you'll still have one of the best cards for your system.
I have a Phenom II X4 965BE @ 4.0 GHz in another machine. It is able to pretty well keep up with a R9-280 and GTX 960 FTW w/o noticeable bottleneck. Just mentioning that for comparison.
