Idea is to buy this:

Asus Maximus VI Formula (C2) iZ87, SATA600 RAID
Corsair 4x8GB, DDR3, PC12800, CL10, Vengeance
Intel Haswell Core i7 4790K 4.0GHz 8MB Box
Samsung LED Monitor S24C350H 24", HDMI (zwart)
Transcend SSD 2.5", 256GB, SATA600, 320 serie
XFX Videokaart PCI-e Radeon R9 280X Double Dissipation 3GB

I have a XFX 7970 HD card and a 700 watt powersupply. And about 8 HDD. 750 watts not to small?

Don't worry, the 700 will handle the two cards. They're rated at ~250W each. Of course, you'd be better off with a 750, but not enough to warrant the extra expense. Relax and build your computer. :)
