Graphics Card upgrade advice

[Stiffaoki]

Hello guys, I would just like some advice or tips on upgrading my graphics card, my set-up is an a10-5800k, 2 x 4b 1333mhz ram, sapphire 6670 and a 600w power supply, i was choosing to upgrade between these cards, Sapphire HD7870, Sapphire Dual X R7 265, Gigabyte Radeon R9 270x Windforce, these cards are 2nd hand though, or should I buy a new Palit Gtx 750ti? your advice is greatly appreciated

270X is 8% faster than the 7870 which is 20% faster than the 265 and that's a good 15% faster than the 750 TI

What model PSU is it? 

As long as its of decent quality, it should be fine, the amount of power is more than enough.

270X uses 160-ish watts stock and 180-190W OCed. As long as your PSU has at least 400W on the +12V Rail I wouldn't worry.

my psu is a thermaltake lite power 600w, should i just stick with it? or buy a new one with 80+ certification?

I would go for the 270x hands down.
