-ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner - Bulk - OEM
-Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case, comes with Three Fans-1x Front Blue LED 120mm Fan, 1x Top 140mm ...

-G.SKILL Ares Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9D-8GAB
-ASUS H87-PLUS LGA 1150 Intel H87 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS
-Intel Core i5-4670 Haswell 3.4GHz LGA 1150 84W Desktop Processor Intel HD Graphics BX80646I54670
-Cooler Master Hyper 212 EVO - CPU Cooler with 120 mm PWM Fan
I can't decide which graphics card to get, I'm in between an AMD Radeon HD 7770, an Nvidia 750 ti, and a Nvidia 760, so which one should I get, considering cost and performance. And thanks in advance if you can find an error in my build or a better component for a cheaper price.

What is the purpose of this PC and what parts do you already have?

 

[SimonSaysSomething]

Is mainly for gaming, and I haven't bought any parts yet, not until I'm sure I'm getting the most for my buck, but of course of a good quality.

Ok then what is your budget and do you need to buy windows or monitor?

My budget is somewhere around 650 to really stretching it 800 or so of dollars, but if I can get a better performance for a better price I obviously would like that.

(My opinion)
U should have better psu brand (SeaSonic or Corsair), because they are more trustworthy
I think if you have l5 4670, you should have a good 200 - 500 dollars gpu.
For me, I think nvidia is more reliable (for me).
So, I think you should get AT LEAST gtx 770 (later can sli it), gtx 780, or even a gtx 780 ti.
But, if you have budge, then...
maybe gtx 750 ti IF you would not play on ultra or best quality.

Here is the best $800 will get you. I asked if you needed a monitor and windows and you didn't answer so I assume you don't. If you do, then this build is no good to.
