Building my own gaming rig for the first time and can't decide on a graphics card.
The choice is between a HD5970 or HD5870. I will want to upgrade and run two cards in the future so I am thinking getting the 5970. I figure i will buy another one in 1.5 years when it is hopefully a lot cheaper. Is this a good idea or should I just stick with a 5870?
Also, do both graphics cards have to be the same?
And what is the difference between a XFX 5970 and a gigabyte 5970 graphic card? which is better
I will be using:
i7 930 CPU
Gigabyte X58A-UD3R mobo
All of the 5970s are reference boards, so it doesn't matter which one you buy. AMD released a GPU Tool which you can use to increase voltage.
If you want to wait, a Sapphire TOXIC 4GB version should come out, but if you want one now, XFX is not a bad choice.
As for crossfiring options, 2xHD5970 won't scale well. You should probably just do an HD5970 + HD5870 TriFire.
