hi all,

soon to get 2 Zotac GTX 285 AMP in sli (priced quite reasonbly at around £450 for 2) configuration on my gigabyte x58 extreme which where chosen after another thread between 295 and 285 GPU selection... maybe would have gone bfg ocx but spec is nearly the same and zotac is a lot cheaper, also have heard recently from a source bfg 285's have high failure rates but good warranties so that also swinged me to zotac as its good having warranty but i have no plans on sending mine back every couple of months :D.

aint gona wait the waiting game for directx 11 cards as i did that for directx 10 and missed out on a lot of good stuff so gonna buy now and make them last another year or so...after all my sli 8800gt are long in the tooth but still play games at 1920x .... sometimes 2560x but no eye candy :(

my question is ... i have a 8800gt card from my old setup which was also in a sli configuration and wanted to know if i added it to the 2 285's as physix card would it show any benefits at all as in increasing performance even slightly?? power aint a problem as i have 1kw psu. and heat isnt either as im using a haf932 case.

or should i go and get 3 zotacs? and pass the 1 8800gt i have left to someone else? the other i gave to my brother as physix for his 295..

p.s i run a 30" i case anyone asks why i need the power and i found gtx285 with 1gb is better on 2560x res than gtx275 896mb.

many thanks

285 GTX SLI can easily handle any physx workload currently with little if any slowdown so the 8800GT may not be a huge asset.

My 260GTX SLI setup completely aces stuff like mirrors edge, etc.

If/when physx becomes more common and more complex implementations then you'd prolly want something faster than an 8800GT any how.

I'd say you'd be better off with tri 285 if your running 2560x res... even when not VRAM limited my 260GTX SLI limps at that res - while at 2048x it flies.
 
also it cant be done. you need to wiat for nvidia to release "SLI2"

You can't have an sli setup with another card doing the physX. I looked into it a lot, asked nvidia directly and since then they now have a nice diagram and details of what you can and cant do in the sli club/physx areas of their site.
 
thought they had drivers wrote so you could use another older card running a physix in tandem with single main or sli cards?

it was nvidias way of recycling older cards and saving you chucking them.

also driver use cuda which uses seperate cards combined for such things as seti... so puzzled when you say it wont work when i remeber seeing ages ago a advertisement sowing that the 8800gt was the minimium grade card you could use as physix

maybe nvidia went back on their project and scrubbed the idea of a seperate card used for physix and i missed that news item stating it had been scrapped...i dont know ???

Pretty sure you can. Otherwise evga's hugely expensive classified board would be pointless.

It supports up to 3x 285 in tri sli with a single slot for physx (9800gt)
 
Don't have a setup to test it atm but sure when I had 3x 8800GT in one PC with 2 in SLI there was the option to use the other one for physx.
 
thanks for the advice everyone..:)

i think ill stick with sli 285 for now as apparently seen reports of increasing micro-stutter on quad 295 and triple 285 and maybe get a third next year depending on whether anyone can tell me is micro-stutter caused by hardware or drivers? as in can future driver cure it? or is it a hardware caused fault during munufacturing process?


many thanks

Does anyone know how to set this up then?

I have my old 8800GT lying around which I could use as my PhyX card until I get my second GTX 275 for SLi.

Is it simply a case of adding it back into my case, and Nvidia Control Panel gives me options from there?

Yep just pop it into your PCI-E slot, install driver if not picked up automaticlly ( should be ), then go to the nvidia control panel and under the physx tab it will say enabled on: and you can pick your 8800 for physx.
 
I m sure you can, just don't connect the 3rd card to the rest or something not sure about Nvida SLI as I never used, yet
