If you post the store that you're buying from that will help to suggest parts. If you don't know one check the link in my signature. As far as video cards go the GTX 550TI is no longer worth purchasing. The 650TI or Radeon 7770 would be far better for the same money. There's no reason to pair a 2500K with a Z77 motherboard as you lose the key feature of Ivy Bridge and that's PCI 3.0.
