I'm currently looking to play some RPG like the fable series, you know, those with spells, outfit costomization, itens etc Any good ideas? It cant be those super giga games such Skyrim since my pc is a piece of shit but games at Kingdoms of Amalur level runs perfectly. So, any ideas?

Have you played The Witcher before? (http://www.gog.com/game/the_witcher)
Great series; but it would lack the outfit variety you are after.

I run Star Wars The Old Republic on my piece of crap laptop, so, I suggest SWTOR! I've been told that after the story line it kinda sucks, but the RPG aspect/story line is amazing. Similar to the older KOTOR games but better. The dialogue system is similar to the one used in Mass Effect(which was also made by Bioware) and choices affect your alignment and the story line in general. 

does it have the customization thing Myrddin? Im more likely to play some real role play, like having houses and etc and kinda based in the mid ages, but if SWTOR have the custom thing i might play it, im a huge SW fan lol

To an extent. You can change the the appearance of your gear/outfit or you can buy stuff from various sources if you don't like the look of what you have.

There aren't any houses that you can buy, but, you can also change the appearance of your starfighters but the starfighter expansion hasn't been released to free-to-play players just yet. 

It may not be as modifiable as Fable BUT it is an amazing RPG, imho and I had to suggest it.

i shall take a look on it, perhaps its time to change from medieval stuff to future ages, thanks for your suggestion bud :)
