I have trouble swapping my GIGABYTE HD6870 to Nvidia GTX770 card, the card powers on, fans on 100% but "No signal" pops up. I tried re-setting the CMOS(took out the battery for 5 minutes), uninstalled catalyst drivers, unplugged extra HDDs.... Now i'm wondering if my mobo is compatible with the "new" card.
My Rig:
CPU: I7-3770
MOBO: GA-H67A-UD3H-B3
PSU: Antec Computer Power Supply HCG-520 (i double checked and it IS enough, even though nvidia states 600w is recommended)
RAM: G.skill 2x2 and 2x4
HDD: 2 Seagate HDDs.

Sorry very simple, but do you have your PCIe cables connected from your PSU to your GPU?

Is your HDMI/VGA/DVI cable connected to your GPU (bottom portion of your case) rather than your integrated graphics (top portion by USB slots)?

Thank you for your suggestion.
I moved two PCI-E PSU cables which are both 6+2 pin and moved them to GTX 770 which requires 1x6 and 1x8 pin connectors.
DVI cable is connected to the card. :)
By the way, my PC is not detecting the card, because when i loaded the PC with my integrated card(and yes it is only enabled when there is no GPU detected) and tried to install drivers "no hardware is detected" message popped out, also card was not visible in "Device Manager".

Unfortunately it sounds like you may have to upgrade to a PSU that has a 6 pin PCIe cable and an 8 pin PCIe cable. Sorry!

Two 6+2 will not work, you need one 6+2 and one 8 pin not 2 6+2 PCIe cables. Someone please correct me if I am incorrect. Please do not take this as a final answer.
