2 cards as Crossfire or 1 better card?

Looking at parts for a new rig, and wondering what the best option is for graphics.

Looking at these cards here:
AMD / ATI - Graphics - buy online - dabs.com

I am wondering if I am best to buy a single card, or buy two cards which are half the price, and using Crossfire for gaming?

sure I'll ignore ya, but I won't ignore Danrok!

Hmm, if you are on a budget, 2 cards for half the price is probably better, but good luck upgrading in the future...
You'll either have to wait until the ONE card drops in price or replace the two with two more...

If you have the money, go ahead and get the single card and then plan to upgrade in the future.

I'm looking at say...

Two of these:
Gigabyte ATI Radeon 6770 HD 900MHz 1GB PCI-Express HDMI (Overclocked) (GV-R677OC-1GD) - dabs.com

Compared to one of these:
XFX ATI Radeon 6950 HD 800MHz 2GB PCI-Express 2.1 x16 DisplayPort (HD-695X-CNFC) - dabs.com

Price is much the same, but the combined power of the 2 two cards looks better to me. Unless I am missing something.

interesting... the 6770 has a higher clock rate but the memory interface is 128-bit.... half the bit-rate of the 6950
I think you would be happy with two 6770's and they will require more power due to having two cards, but I guarantee... 2-3 years from now you will want to play the newest Crysis or FarCry and they will start to lag.... no hope of upgrading at that point.

If you get the 6950 it will still perform as good at two 6770's, generate less heat and require less power.
In a few years you will be able to purchase another one for probably half the price (off Ebay of course) and be able to play all the newer games....
of course you will have to watch your Power Supply to make sure it can handle two of them.

by the way, does your motherboard have two PCI-Express slots or PCI-Express 2.0 slots?

I'm buying all new parts. So, a total upgrade of my desktop which is old now.

I think you're right, double the memory bus should be better.

I was asking because the 6770 is only a PCI-Express card... not a 2.0

You won't regret it in 2-3 years when you want to upgrade again.
Correct me if I'm wrong, but doesn't Crossfire work with different GPU's these days?
So if you can't find the exact 6950 later one cause they don't manufacture it anymore, you should be able to Crossfire it with a newer card.
