Benchmark: AMD driver 13.3 vs 14.4 on R9 280X

Yesterday the new AMD drivers came out. I was curious how they would preform on my R9 280X. I was expecting a increase in performance, but not in the games I currently play.

Information 

The specification's of my gaming system.

• Intel Core i5-4670
• R9 280X
• I over-clocked my card to 1100Mhz on the core and 1550Mhz on the memory.
• Full specifiation's

The games I have used. All games were on maximum graphics on 1080p resolution

• DiRT Showdown
• DiRT 3
• Assassins Creed III
• Assassins Creed IV: Black Flag
• Need For Speed Rivals

Also I have ran the Performance Benchmark of 3DMark 11.

The results:

Conclusion

After these results I am very disappointed in AMD, the 14.4 drivers preform worse or equal to 13.3. Maybe the results on a R9 290(x). Maybe I will do the same tests on my HTPC which is equipped with an R7 260x.
