i have just bought a new computer and i think i would like to get another GPU to run SLI... i just have a few questions about it... the GPU i have is GTX 275 so im going to get another of those and i know my motherboard supports it... what i would like to know is if it has to be the same brand and does everything in it need to be exactly the same? im quite sure my cooling should be enough but i have a 750W power supply, do you think that is enough for it?
Also if there if there is anything else i should look out for before getting another GPU please tell me also just ask if you need some more information about my system
A 750w PSU is more than ample to run 2x275 in SLI (Inter-tech - never heard of them!)
U dont NEED a single 12v rail to run multiple GPUs but it is recomended to reduce spiking on one card.
And to whome ever sugested remove the 275 and buy 2x5850's thats not really a sensible sugestion, a GTX275 costs about £170, each HD5850 cost about £200.
The card just has to be a GTX275, (different make (asus/gygabyte/xfx) - dont matter). It does not matter if one card is running at reference clock speeds and one is overclocked.
And no, 2x275 prolly wont run crysis at max settings, that game is just a killer!! but it dont really matter, still looks damm good !
So in essence, all you need is a 2nd GTX275 and a SLI Bridge.
Thank you for the answer but dont you think it can run crysis maxed out? ^^ atm im running 8x AA and everything in very high except shader and postprocessing(which are one of those taking much FPS though) at around 35-50 FPS(bit depending what i am looking at) but well at least i guess it will run better though what is a SLI bridge? ^^
of some reason i didnt receive an email for confirmation of account so its me, the on called anonymous ^^ :S
Anyway i have heard that i need something called a SLI bridge, what is that and could it already be implemented in the pc or something? ^^
The GTX275 SLI won't max Crysis (GTX295 = 2x GTX275), and there's minFPS issues as well.
Cygone, my suggestion of selling his $260 card for a $300 one that dominates it isn't a bad idea. He's planning on buying another one, so he is planning on spending that much already. For an extra $80, he can beat his setup, be guaranteed his powersupply will hold, and output less heat.
well tbh i cba to sell my GTX275, and also im more of an nvidia fan, had problems about ATI...
guess it might not run crysis maxed out but i would be able to live without it
and as far as i know, none games so far requires as much as crysis right?
yes that is true but as i said i cba to sell my other one here and as far as i know it dosent peform much less than 285 SLI which is around the same as 5850 it seems ^^ i know its a minus with DX 11 but most games will still run DX 10 for a year or 2 i guess, and then i will probably just buy something new
