Hi, 

I am Aung. Nice to meet you all.

I want to buy Dell Inspiron 620  form one of my friend. Currently with Core(TM) i3-2120 CPU @ 3.30GHz (4 CPUs), ~3.3GHz. I think its Intel H61 Express Chip.

I will upgrade this pc after 6 months or more then 6 month. 

I do want to know that Can I Upgrade that PC to Core i7 ?(Third gen - fourth gen). Can I add graphic Card in PCI-Experss (Gtx 750)?  Still worth to buy and Upgrade-able in future?

Thank you

Regards

Aung
