It will depend on what you feel the machine is lacking for you. Is it gaming? The A6-3620 quad core (actually, 2 Bulldozer cores) and the HD 7770 are well matched. It should do well at 720p with max/near max settings. If you game at 1080p, you will have to back off on some settings to maintain smooth frame rates in the more demanding games. A faster card will help there. You have sufficient RAM and a nice sized HDD. A SSD will improve on response time, but will do nothing for gaming other than load the game into memory faster.
