Due to the insufficient performance I have my Geforce 220 replaced by a Palit GeForce GTX 660 Ti graphics card. The graphics card was recommended by a colleague for a very good price - performance ratio recommended.
I had quite a high increase in performance after installation in my PC. The Windows Experience Index rose from 5.9 to 7.3. Also I can play Diablo 3 on the highest level of detail with my i5 750 now.
