According to game-debate, you won't be able to run these games. Your graphics card is the biggest bottleneck, it has a performance rating of 2/10 and any of these two games require a minimum of 4/10 performance rating.
Conclusion: your pc does not meet the minimum requirements, but at the minimum possible settings and resolution you can play these games. Of course it won't be a very enjoyable experience :| GTA 5 will have ~25-35 average fps and COD Ghosts will have ~25-30 of average fps, but people say it is freezing sometimes because of low cpu speed (it's only 1.7GHz). If you think its good enough, give it a try.
