NVidia gtx 550ti vs hd6770

[jimakos101]

Hello, i am wondering which gpu should i buy and which is better.


Gainward GTX 550Ti

Chipset: NVIDIA GeForce GTX550 Ti.
memory: 1024MB GDDR5 at 192-bit.
Engine Clock: 900MHz.
Memory Clock: 2050MHz.
RAMDAC: 400MHz.

or


Asus HD6770 DDR5

Chipset: AMD Radeon HD 6670.
Memory: 1GB GDDR5 (128bits).
Engine clock: 810 MHz.
Memory clock: 4 GHz (1 GHz GDDR5)

Which one is the best for gaming,also the gtx has lower memory clock that the hd,does this says that the hd is better???
Also, will a corsair 430CX will be enough to power up these cards?(no crossfire,no SLI)

EDIT : THE GPU WILL BE COMBINED WITH AMD PHENOM 2 X4 965 BE

You mean a 6670 btw.

The GTX550 is a much better card. I think your PSU should be ok as well.

This is a great website for checking this.

In general the GTx 550TI is better than the HD6770
