6870x2 PSU Requirements

Hi,

I'm currently upgrading some of my components including the graphics card.. (my pc is for games)

I am purchasing a 750w psu, and I was planning on buying a GTX 570..

On the website that I will be buying from, they recently put up a special for a "6870x2 2gb" card, at only $400 (roughly what I am spending on a 570)

Here's a link to the 6870x2:

My questions are:
1. Is the 6870x2 better than the gtx 570?
2. And will a 750w psu run the 6870x2 fine with no issues?

If it matters, the other parts I am getting are:

i5 2500 - cpu
ASUS P8Z68-V LE - mobo
Corsair TX750 80 plus - psu
G.skill ripjaws 8gb ddr3 ram

Thanks

  1. Yes the Radeon HD 6870 X2 has a substantial performance advantage over the GeForce GTX 570.

    For a system using a single Radeon HD 6870 X2 graphics card AMD specifies a minimum of a 600 Watt or greater power supply that has a combined +12 Volt continuous current rating of 45 Amps or greater and that has at least two 8-pin PCI-Express supplementary power connectors.

    The Corsair Enthusiast Series TX750 V2 (CMPSU-750TXV2), with its +12 Volt continuous current rating of 62 Amps and with its four 6+2-pin PCI-Express supplementary power connectors is more than sufficient to power your system with a single Radeon HD 6870 X2 and has ample reserve capacity for any overclocking of the CPU and GPU you may want to attempt.
