the tpu numbers are off compared to everything else i saw so far...
i liked the xbitlabs one best so far, they test a lot of games in a lot of res, they use aa and af in a very smart way where it makes sense, and they show min and max fps and all details in how they tested...

for xbitlabs the 5870 is give or take the same as a 4870x2 in performance, sometimes slightly ahead sometimes slightly behind.
its clearly slower than the 295, but not by a huge margin...
the one thing that looks odd on xbit is that the 295 DESTROYS both the 4870x2 and 5870 in hawx... it looks like they tested in 10.0 and not 10.1 and even then its really weird...

after reading the hwcanucks and xbitlabs review i have a much more positive picture of the 5870...
looks like its about the same as a 4870x2 but its one gpu and not two, which is a plus, and it has some improvements over the 4800 series...
but the price is still not right... how can it cost 50$ more than a 4870x2? which performs about the same or even better in some sitations?
and the very poor overclocking results on 5870 cards really suck too, only 5% according to tpu, thats a joke... even a super hot 4870x2 ocs better...
