Which one is a better graphics card?

[ExperiencedNoob]

I changing my old graphics which is ATI Radeon HD 4600 Series. I'm choosing between ASUS HD7790 1GB DDR5 128bit and ASUS GTX750 TI 2GB DDR5 128bit.

Which one is better?

Also this is for gaming purposes..

GTX 750Ti. More processing power, and it doesn't use much power, requiring only the power supplied by the PCIe slot.

http://gpuboss.com/gpus/Radeon-HD-7790-vs-GeForce-GTX-750-Ti - the 7790 is better.

Just make sure it fits your case and your power supply can reliably run it.

But the 7790 only wins in 3DMark06?

Oh okay. So how much power does it use? I have Gigabyte GreenMax 450W

7790 - 430W, GTX 750Ti - 400W

Your Gigabyte PSU is not in tiers 1, 2a or 2b of http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html
so its not very good quality.

But can I still run 7790 or the GTX 750Ti?? Or do I need to replace it?

It's up to you. I certainly wouldn't have even bought it with what I know now.
