Swiftech pump will be powerful enough for the job but i might add in another radiator for the GPUs just to be safe as i have the space and it will help with the plumbing, plus my house has some really nice A/C my wife hates the heat so its always on some times ambient is as low as 18c
At PAX Australia i saw this pump and rad on triple GPU setup so it can be done, but its the design of my case that wont allow it plus two radiators looks good im also looking at getting them chrome dipped so they are all shiny bling bling just waiting to here back from Swiftech support if that does not pan out i will get different type chrome treatment done but this is longer term plan my main goal is to have case chromed saw a case at PAX chrome and it looked crazy
Plus that way when i polish the chrome on the classic car i can come inside and polish PC to
For me the two 1080s will be my last GPU upgrade for quite sometime with a baby on the way im getting all my PC upgrades out of the way now so im set for a long time I currently run 4 screens now and looking at getting HTC vive soon plus i have been doing some CAD work so it really helps with heavy renders having two cards.
Since last few updates i have been alot happier with SLI and SLI defiantly helps in games that support SLI
With this new Swiftech cooling system i now idle at 24c 50% fan and at full clock under stress test i hit 62c at 4.7 MHz with fans at 95%
On old cooling Fractual designs system i would idle at 35c fans at 50% and at full load stress test i would hit 88c fans at 100% at 4.6 MHz
Cost for cards is around $3000 give or take some as they don't let you pay in full until they arrive so they only take deposit think 40% like i said its not so much for braggin rights its more about getting the dream PC i have wanted all my life before the baby comes and starts taking my money
