5870 Crossfire vs Fermi SLi

At the top end of the scale it's pretty much a given that SLI scales better then Crossfire with this generation of cards, mid/high range (HD5770/GTX460) it's a bit more even. Nvidia may have struggled with the hardware side of things but there driver team has at least given them the edge in multiple video card setups. There's a review over at Anandtech just the other day, I suggest you have read.

gtx 460 sli is even with 5770 cfx ??? according to hardocp gtx 460 sli beats 5850 cfx and for less money

SLI wins, but costs more, is warmer and uses a lot more power. Crossfire not far behind (except where heavy tessalation is used) uses less power and is cheaper

Most people would have to factor in a replacement PSU for 480 SLI unless they already on a high enough spec one

ATI wins...

Has been discussed over and over...

Buy 480GTX SLI and you will need a new PSU costing £200 :P ATI on the other hand is A ok with a normal 750w psu

he never actually said what Fermi card, the only information we have is he wants to know if two fermi cards in SLI are better or worse than two 5870's in Crossfire.

performance wise GTX 470's and GTX 480's beat the 5870's, price wise it's safe to say the 460's and 470's kick the 5870's ass, price performance wise again the 460's and 470's easily (it really is the right word when you see how much you save and how performance compares) beats the 5870's.

like how heat wise although in new cards it doesn't really matter 460's > 5870's but 5870's > 470's and 480's with the best having the lowest temp. Same goes to power draw except 5870's win against all of them, and finally noise 460's>5870's which beat or are about the same as 470's which are better than 480's
 
In my personal experience SLI has always had slightly better implementation than crossfire so if I was given the option of one or the other I'd choose SLI.

However, I don't really like multi GPU solutions (I generally get two cards to play with then end up selling one) so I'd always advocate going for the fastest single GPU.

What will be the right choice for a given individual will depend on the games they play and at what resolution they play them.

Wow look at the 5870 go :o

Yeah it seems to me that the nividia cards are better in SLI, but only at the higher resolutions (which you should be running if you have such a big setup :p)

Again what these reviews fail to consider is a 5970 + 5870 CF set up, which is what is comparable in price and power consumption to a 480 SLI setup

yeah but for that price you could also get 470 tri-sli which easily beats 5970 + 5870 CF

have you got any V's type benchmark links? its not that i doubt you at all its just i only found 1 V's bench on a german forum, he showed 470 tri sli beating trifire 5870's (not 5970+5870 :o ) buy 2fps @ heavan 2.0 (77 for tri sli 75 for trifire) but id like to see some BFbc2 results, ive got 2 5870 vapour-x's atm and im thinking of selling one now and the other when the ATI refresh comes out as they refuse to play ball if i try to OC them :( .. then decide on ati or nvidia for a new multi gpu setup to last me a few years :)
