Hi to everyone since i'm new to this forum. Wanted to ask about card options, i have i5-760 on P7P55D-E PRO and msi gtx470 twinfrozr, monitor acer gd245hq +3D vision, with this setup on some games my fsp is struggleing, so i was thinking to add another 470 in sli since now the price on theme droped, is this a bad idea? will i sacrifice alot in x8/x8 configuration? Or i'm better off selling my 470 and geting gtx 580? Thnx for reply
 
How much space can you leave between them?

If the answer is AT LEAST two slots and you can mod in a 120mm fan to feed them? sure roll with it.

Are the P55 boards all micro? if so then I would strongly suggest not going there mate.

Pics would help.
 
Don't have pics of my case, but ya it have 2 slots beetween, and the case is HAF 922, 2x120 side fans blow fresh air for card

Na, the P55's are full ATX standard.

I'm using a P55 and was thinking of doing the same thing but as AlienALX has said, it would depend on the PCI-E slot layout. You could in theory run them straight on top of each other but the top card would get very very hot.

If you were wondering about whether the slots could handle it, again some of the boards run 8 x 8 on the PCI-E lanes and others split them differently. However, if it is 8 x 8 then that would provide enough bandwidth for the cards.
 
I wouldn't even think of geting 470 with stock cooler on it, i have MSi 470 twinfrozr II, so i'll add the same one

Oh yeah, just checked and your lanes are like this so you're fine - 2 x PCIe 2.0 x16 (single at x16 or dual at x8 / x8 mode
 
not a massive loss using dual 8x tbh. But, I guess it's a loss all the same.

Lovely cards you have there mate. Should scream

That means i'm good to go with sli, thnx for such fast reply.

P.S now thats a find of the day, definitly will stick to this forum
 
Yeah I hear ya man. I mean, depending on your CPU those cards in SLI are so fast that like me you could hit a dead end. My 470 beats Crossfired 5770s in my machine and I'm certain that was down to the CPU holding them back.
 
i5-760 at 4GHz, like majority of i5-i7 users, dont have HT but that wouldn't help for games anyway, i kinda hoped my CPU wouldn't bottleneck 470 sli, or i might be wrong?
 
I know that SLI 580 were bottlenecked by an I7 965 OC, amazingly so in Tri SLI.

What you will need to do is real world tests (bench before and after) to decipher your gains. But, I would strongly imagine that your CPU will allow them to stretch their legs very well.

You are also running dual 8x, meaning that will stop them from being as bonkers (5% or so reduction).

You should be fine dude.

Please though, post back with your results !! No one has statted up some proper in depth benches with 470 yet
