Topic: which video card is better? (Read 454 times)
Ok thanks. I understand it's best but it's all I have, I'm trying to make do with what I have! I'm just hoping the 6570's will be functional!
When Adding a GPU to your computer, Its best to NOT HAVE A STOCK POWER SUPPLY OF 250-350Watts!!!
You should have a 400-700watt PSU for crap sakes if your gonna add a 6xxx

thanks. from what I've read, I should stick with the 6570 though, as the 6770 needs a lot more power and a separate power connector? Just seems safer to use 6570 regarding power requirements.
The PSU guidlines are generally 2x or greater than the actual power draw.
You'll probably draw 200-230 watts.
Worse that happens you break the PSU
If you use PCI-E to molex adapters spread the load out over different power wires.

Note if you overclocking GPU to its max it can take like 25% more watts than official max consumption.
Plug no more than 80% of your PSU to it or the life of PSU will be not long.
If you dont have free electricity then you wasting more money than you can mine - or buying coins directly is cheaper.

Yes, power supply matters. Your computer may not be stable if the PSU isn't big enough to handle everything.
Thanks for your response but those are my only 2 options.
Actually, I just saw that the 6770 says it requires a 500W power supply and my comp doesn't have that. So I guess I have to go with the 6570. I don't know, I'm trying to figure this out so any help is appreciated. I have 2 computers, 1 has 300W power supply and other has 350W. Does power supply matter where it says recommended power supply 400W for the 6570? Thanks

I have 2 options: either I get this video card: XFX - ATI Radeon HD 6770 1GB DDR5 PCI Express 2.1 Graphics Card and run it on 1 computer.
OR
I can get 2 of these and run them on 2 computers: XFX - Radeon HD 6570 1GB DDR3 PCI Express Graphics Card
Which will get me the most Mhash/sec? Thanks a lot!
