Sus 550 JX came with HQ processor and first class GPU installed with DOS. Its equipped with Driver DVD. Not to forget the ASUS support which is equally great, we can get updated drivers from there. No problem with ASUS product registration.
I installed windows 10 it uses 2.2 GB Ram in total ( 1.8 GB Windows + 300 Mb additional drivers and services) . I played CS, FIFA 13 and NFS MW 2012 without any lags. Battery approximately 1 to 2 hours of backup. Around 1.8 GB Ram is available ( that can be increased though) and average HD display. In this budget its the best deal.
