Sli & Phys x

[ChrisLandin]

Hi all. I have a striker 2 formula board and a pair of GTX 275's in sli. My brother's build has just gone to meet the lovely mechanical maker in the sky and he had a GTX 260 in his rig. Its fine ive tested it, my question is this, I currently run my gtx's in sli in ports 1 & 3 like in asus instructions, what I want to do is add in the 260 and let in take care of Physx for me, this is possible right!! The question is do i just plug it to the board and attach power and away I go, or do attach it to the sli bridge or go out and buy a flexible connector and bridge the 2 x 275's and leave the 260 out of the loop?
I know a lot of people will post back saying why even bother but seeing as though its sitting there doing nothing at the moment I thought I would use it and benchmark the setup.
Any help out there??

275GTX in SLI will eat any physx workload currently... 260 would be an expensive and hot way of handling it for an extra maybe 1-2% performance in todays titles...

and as it appears nVidia have screwed physx in the nether regions anyhow it looks like we won't be seeing anything coming out that would take advantage of an extra physx unit of the power of a 260 anyway.

Cheers Rroff, I was sort of hoping you would see the post and reply.

Cryostatis (oof trying to type that drunk :S) aside, everything else that uses phsyx runs butter smooth on my 260GTX SLI even mirrors edge. Cryostasis isn't exactly the most optimally programmed at the best fo times.

they both should hnadle physics, if you really care about making them work on redering only you only need a 9600 you don't need anymore than that(so i heard) using a GTX260 as physics is a waste tbh

 

[Rroff]

9600 is ok but its only 64sp - something with 96-128 sp is better... that said tho - even in cryostasissasadsad you'd prolly see very little difference between a 9600 and 260 - someone should test it

no, i was going to but since Nvida don't like you buying thier cards just for physics i can't any longer (damm you Nvida)

I was going to get the foxconn and a 9600GT install XP than test that, however I cba to buy a GTX260 as well nor have the monies

plus there is a thread about on this fourm so it will just disable the physics -.-
