I ended up buying an other one for 400 dollars.
Its not the best, but deffinately worth the cash.
6GB Ram, 750GB HDD, Intel(R) Pentium(R) CPU G630 @ 2.70GHz(2CPUs), ~2.7GHz, NVIDIA GeForce 510.
Including a screen, speakers, microphone, keyboard+mouse, and its only 7 months old.
This gamer guy sold it to me, and he showed me how it runs Battlefield 3.
oh god it ran perfectly fine on a high quality mode while radio was playing on the background with minecraft started(no fps stuttering, even when you get blasted hardcore cqc)
I'm so happei
thank you to everyone who took the time to leave a reply.
