Is this build compatible and/or is it good?

Good choices, but I don't know about the video card (I'm not a gamer).

What I read about it is that its quite good, I would like this setup to last a while xD

Get a 2GB 560TI so you can easily SLI later on. It won't last too long in gaming especially with a 1GB frame buffer. Its pretty much the thing stopping you from SLIing those 560ti bad boys.

The graphics card should be okay, there are 2 concerns for me..

1) You dont have another HD? 1 128GB SSD isn't going to go very far all by itself

2) The 650W PSU is potentially low-end for your system. I believe it will run everythign you have listed, but if you get to upgrading your card in the future or soemthing, you may end up double-upgrading the card and psu at the same time.

Not 100% sure how far 650W will take you, but there are websites to calculate that stuff for ya  

Yeah, I have another HD that i did not list, about 1 terabyte
Wow, what i read before was that 650 W was already overkill...
And about the graphics card, i shall look and see how much that costs
Thx for the replies ^__^

I would not go OCZ for your SSD. They are having financial issues and you don't know where they will be in 6 mos. I suggest a Samsung 840Pro and if you need something cheaper, a Crucial M4. I had a 128GB drive and had to upgrade to a 256GB cuz it was just too small. You may want to think about that. The rest of your build looks fine.

CPU : i5-3570k, nothing to say here.
MOBO : i'd ditch the asus for the ASRock Z77 Extreme4 more oc with this board plus 8 sata connectors and better audio on-board.
RAM : its ok, although i recommend the CORSAIR Vengeance 8GB CML8GX3M2A1600C9 if available in your area.
CPU COOLER : really good cpu cooler but it is really expensive i'd trade if once again available the Cooler Master Hyper 212 EVO.
VIDEO CARD : now here i really recommend ditching the 560ti for a 660 gtx 2gb or 7870 2gb (depending on your taste for brands) in your area.
SSD : look for Crucial CT128M4SSD2CCA (128gb) cause its better.
PSU : the antec is more than enough even with two 660 gtx or 7870 sli/crossfire so you'll not be needing more than the 650w.
