Purchased replacement of Athlon II x4 620. The difference is not striking in daily use but in games I went from 50fps on World of Warcraft at 90 fps! On Bioshock infinite I went from 40 to 63 fps on average!
Level applications no visible difference except for heavy programs such as After Effects or x264 compression which, without exaggeration, it happens 2-3 times faster!
Finally, a versatile processor that fits all use. Do not disappoint me!
