Considerable upgrade... [0.1]

So I am going to upgrade for my ancient cheap ass build from 2006 so here: 

CPU: AMD Athlon x2 4200+ RAM: 2Gb DDR2 667mhz GPU: Radeon HD 2600xt 256mb GDDR3

Since I have a tight budget and trying to expand it, this is for now my build... I update it if I can put in the bugdet for upgrading. I am from Croatia btw.

I'm sorry, I really have no idea where to go to look for parts in Croatia... If you can send me a website (preferably in English) I'd be happy to help you look. Also a budget would be great.

If you want a suggestion simply about parts that I THINK might be cheap where you are in Croatia, I would recommend going with an AMD A10 5800k series with an FM2 motherboard, probably of the A75 series from ASRock due to their crazy memory speed capacity. Then as fast of RAM as you can afford (1866 MHz or 2133 MHz) of 8GB flavor (2x4 GB sticks work better than 1x8 GB stick.) And then I'd add a Radeon HD 6670 for dual graphics. Then find any nice 500W power supply and whatever case you like.

could you give us a site, from croatia where you will buy youre stuff ? :)

and youre budget ofc

Well I am upgrading but buying used parts, so that it will fit my 110$ budget :P

I would buy it if I could anyway the site where people buy used or even brand new stuff, njuskalo.hr and you can force translation into english if you use google chrome...

I'm sorry, I can't figure out if Google is mistranslating this, because the idea that a Pentium 4 HT is 130 pound is a huge amount of inflation. If you must have used parts, try to find something AMD Phenom II X4, they are still very nice, and usually relatively cheap-ish. But I do have doubts that you would be able to build anything for $110... I'm really hoping that a zero is missing.

My budget is small, but I may expand with my help of my dad. I only want to know what games I could play with this configuration and if possible. I din't mention the motherboard since its not really revelant... I am still choosing what to use...
