Help me upgrade my PC (1440p or 4K)

Hello everyone. How's it going?



I'm thinking of buying TITAN X (SLI), but my PSU and other pc specs are holding me back. Would you be kind enough to have a look at my pc specs?



Current PC Specs:

i7 3770k (stock)

Gigabyte z77xud5h motherboard

corsair vengeance 1866mhz 16gb (2x8GB)

club 3d 7970ghz Royal ace (stock)

corsair 850watts psu

2TB WD HDD

1TB Seagate HDD

128gb corsair neutron SSD

Corsair h100i cpu cooler



Does my pc need an upgrade at all? is my psu powerful enough to power 2x TITAN X?



thanks and have a great day.
