I had worked on Core2Duo laptops running at 1.6 to 1.8Ghz with 2gig ram lang. Grabe.
Honestly, everything is working fine naman. mababa naman ang specs ng programing, kayang kaya na yan. Ang games ang mataas.
Core2Duo - 2010 to 2012 laptop should and would probably priced at around 7to 10k.
hanap ka ng Intel Based I3 to I5 laptop priced at 9k to 15k.
and to make it safe, kuha ka with reputable brands like Lenovo, Dell, HP, Sony, Asus, MSI. IMO, dyan lang ako nagtitiwala.
Second choice line up ko is Acer, Compaq.
Da rest, wag na lang... wag kang kukuha nang Redfox.
Ideally, get I3 or I5, right brand, then 2gig (nakukulangan ako, pero you can start with this, better yet, get 4gig to 8gig.
Sa HDD, minimum is 120HDD (mababa masyado to). pero 250HDD will do
more than 250HDD tapos tatamaan ang pricing, wag na lang rin, meaning di ko ma-advice. di naman bumibilis ang PC sa HDD. and HDD is more of another topic and does not complement speed.
