Thanks for the fast reply. I was having doubts because in the place im buying it from it says the second PC is good for gaming, because of AMD processors and ATI cards, and also because of Vista (Direct X 10).
But I guess it's first one then. Also, I'm buying them from a place in my country (Bosnia), and the site is
A-computers web katalog proizvoda
About the price, I can't say exactly, because on the page the price is together with monitor, speakers, keyboard and mouse. But the prices (with monitor etc.) are:
First PC: 1599 KM (1152.35$)
Second PC: 1399 KM (1008.22$)
EDIT (just saw puddles reply) I would also like a quad core, but I just can't find one... Everywhere I look (note: I don't want to buy it online) it's always few good parts, other bad, or few bad, other good.. Like, 4 GB ram with 256 MB video card for example...
And, I don't know about building it my self. I know it would be the best but... Never build a PC before.. :/
