Agreed. I'm not exactly sure what kind of point he is trying to make. His entire rig in his sig is complete overkill for older games anyway, so what does it matter that Crossfire drops to 1 card in them? It works when it matters, and that's really all you need to worry about.

Crossfire and SLI not the same??

With the latest beta of ATT you can define what crossfire mode you want the game to run. They're 4 in total. AFR being the most popular and quickest, Scissor which splits the screen in 2, tile or chess board, where the screen in divided up into a grid, one card does even squares the other odd. Last but not least SuperAA. This mode doesn't increase fps but image quality. One card does on frequency of AA the other another pass effectively doubling AA, so you get better IQ without the fps hit. Hope that's right.
I count 3 ways to crossfire!!! Yous aid AFR, Scissors and SuperAA. What's the fourth??
the fourth is tiled. Like a chessboard, one card does the 'black' squares, the other does the 'white'.

hybrid is for matching same brand cards still, like using the amd 780g(i think its that) along with a normal gfx card and getting a little boost, it seems to work ok, but really isn't the best option around. ITs semi economical as the price increase from a non intergrated board, to one with intergrated gfx has been set very very aggressively, so you get like a £20 onboard gpu for £5-10extra. Really its only a good reason to do so if you aren't building a gaming rig and at a later date decide to buy a discrete gfx card, if you plan to game, just put the money towards a better card.
But the numbers aren't too great, its very very algorithm heavy and the reviews i've seen aren't great. 4870 cf + a 4850 was slower than the 4870cf'd alone, except in 3dmark where it was faster, and maybe one other game. Shockingly the more you vary the possibilities the more complex the calculations and balancing algorithms get.
Frankly 2x4850cf'd + a 4870 isn't remotely appealing at all, it creates more problems than it fixes and would be slower than the 4850's alone in lots of games, even if it were faster, selling both 4850's for £80 each or something and you've covered the cost of buying an extra 4870 for normal crossfire and much better, less complicated and less power hungry performance, that would need a less powerful gpu, less case cooling, less space and a cheaper motherboard.

MSTS barely makes 30fps (12 through clapham junction) with a decent amount of AA on.
GPL still chokes on the run down to the first corner.
Anyway from the list posted here regarding Xfire (have seen no such list for SLI), there are only less than 100 supported games, that's less than 1% of PC titles.
As I said if all you play is AOC and Crysis, maybe it'll help, but not everyone is a fashion victim who thinks anything older than a year should simply not be played, so peopoe should really find out what a person plays before reccommending Xfire/SLI.
Plenty of people told me a 4870x2 would be PERFECT for me, until I found out that it doesn't flaming work with any games I play very regularly (for instance Rfactor, GTR, GPL,GTL....all of which MORE than beat my GTX280 by the time I turn AA up to 32SSAA+SStransparency @1920.)
Oh but I was walking about a 4850+4870CF, not 4850CF+4870, this would be a three card, which I don't plan to do at all.
It's just that I was setting myself up for a single 4850 and then another 4850 down the road, but at this rate 4870 looks to be of a good value so I was thinking about this new option.
Correct, so if your running a 4850 with a 4870 in Crossfire, then they will be faster than 2x 4850's.
They are maybe 3fps max faster in some games, the same in others from the benchies I've seen, not worth it.
Is it actually worded for the modes now in the Beta's ?
