Looking further and seems almost certain that all scores are measured with one core, even on dual core cards. Look at the score of a single HD4870 compared with a HD4870X2, that's not right imho.
So then in actually the 5970 creams basically every card on that list? How do you force it to only use 1 core though? Is that built into the ATI softwarE? I've never used more then 1 card since i'm too cheap to get anything else... and i think SLI/Crossfire is a gimmick. If and when lucid ever comes out then i will buy multiple cards.
If that's the case ignore my last statement and yeah... lol.
Yes at the moment the HD5970 is the fastest single card solution available, given that the program has multi GPU support.
That's wy Nvidia pushes so hard to get the Mars II card released, Nvidia want to reclaim the title of fastest single card manufacturer.
HD5970 isn't the fastest 2 GPU solution tho. 2x HD5870 in Xfire will be faster. Also 2x GTX480 in SLI will be faster tho it will be a lot more expensive and will run a lot hotter then a single HD5970.
You can assign a GPU to specific processes and so force single GPU usage, you don't want that tho, is often the challenge to get the program to use both GPUs and so get the most out of your videocard.
SLI/Xfire certainly isn't a gimmick anymore as stated before. Biggest drawback of SLI/Xfire is that you have to totally rely on the program engine to take full advantage of your set-up. Some programs scale perfectly when using SLI/Xfire and some others totally not and then is a waste of money ;)
Although is not as bad a a couple years ago. Back then i had 2x 7900GTX XXX 512MB in SLI (rare cards, payed €710 per card :-P ) and 8 out of 10 games didn't do anything at al with the second 7900GTX XXX 512MB. Was an early adopter back then and payed the price for it :)
FFXI benchmark totally relied on processing power. The slightest OC of your CPU gave you many hundreds points more. Eventually i broke the 10.000 barrier with an OC AMD Opteron 180 and a ATI X800 Platinum.
Think it will take (a long) time before i get even near 10.000 with the FFXIV benchmark >_>
