Hey guys, was wondering if anyone has a dedicated PhysX card on their system, and if it provides greater performance?
im thinking of using this GTX260 for PhysX and the GTX 480 for Graphics, i know that the only game right now that uses PhysX is UT3, but i have a feeling alot more are comming out in the following months.

I did and it does.

Sli works better than physX/Single card but it is better then just a single card (or so my experience has been this way)

I was running 2x640mb 8800GTS's in both configurations but had issues with one card artifacting so i pulled it back to being dedicated physX only

Thanks Daemon, i just hope this 770w PSU can provide enough juice for the GTX480 and 260 all at the same time while OC'ing my CPU and RAM lol.

nvidia has now dropped the aegis and physx support, so dont expect it to be a big thing in the future, expect the cpu to do the work

unless nvidia monopolizes the gaming industry

although i hate ATi with a passion, im leaning over towards 5970.... i know 480 is the fastest single core, but the 5970 is like 2 in 1, with about 30% increase than the 480, might get a 5970 and use this gtx260 as physx.

I was the same as you guys, i loved Nvidia once but then I couldn't be f*@ked waiting for them to dick around with their directx 11 cards (and lets be honest what they have come up with is pretty pathetic really), so i converted, and i have never looked back since. ATI has insane power and is incredible good, Temps are great and they OC well. Plus ATI is cheaper than Nvidia and thats always a bonus.

Joker, GTX480 has less heat output then the 5970, i know it might be power hungry but its the fastest single gpu in the world...now that im looking at the 5970 im not sure, i mean, ive seen alot of benchmarks, and ive seen that the GTX480 has less fps, but it has smoother play, whilst the 5970 has more fps it has micro stuttering.

still guna do some research and see what i should go for but the gtx480 is in my mind cause im guna use this gtx260 for physx, as Troppo told me earlier, If you mix nvidia and ati youll be sorry (as for using physx with nvidia).

ive seen many reviews dude....and in game heat temps....480 is lower,

Temps: Initially 480 lower, then they stay around the same with minor flucts, https://www.youtube.com/watch?v=ii90EQF6CmA

and https://www.youtube.com/watch?v=eras9dtIuUE&feature=related initially has more heath, but deals with it better as time goes on.

Nonetheless 5970 does averagely beat the 480, but ive had nvidia from
4200
6600
8800
9800xt
9500gt
9800gtx2
Gts250
and now the GTX260

not guna break the link cause of this new 5970 =P

Virt the 5970 runs quite alot cooler than the GTX480, i'm reading a review on the GTX480 right here by Atomic, they tested the GTX480 in open air and its load temps were 94 degrees, that is bloody hot. The 5970 didn't come near that heat. Plus the 5970 beat it in every test, and in some cases the 5870 beat it. At the end of the review they pretty much said that the GTX480 is the equiliviant of the 5870 and that you should buy an 5870 cause they don't heat up as much. Now you have to admit Virt ATI has won this round.

Yes Yes, ATi has won this round, but the next batch of nvidia cards are destined to win.

also, joker, i OC'd my i7 920 to 4.1 but never ran torture tests lol....after doing so it was unstable.....the stable MAX clock for my i7 920 is 3.88Ghz, well atleast untill i need to RMA and get a D0 batch xD
and my RAM ocs like a mofo lol 1900mhz from 1066 but again its not stable, ive got it currently on 1500mhz on Extreme performance, will also be buying the GTX 480 because i dont want ATi in my list and 2 1TB HDDs to run in Raid 0 as opposed to my other thought of getting SSDs.
Although the 5970 wins this round, GTX480 offers a few things that the 5970 does not, fermi, cuda cores for smoother gameplay, PolyMorph Engine, Ray Tracing, GigaThreadTM scheduler allows up to 10-times faster switching between graphics and physics processing, enabling more complex effects to be rendered in real time. (which is why im having second thoughts of enabling my 260 at a dedicated PhysX, but i will be runnings tests to see if it will have better performance.),

Although if this GPU was released beginning of this year, it woulda been a huge leap for nvidia.

I have D0 stepping on my 920 and I have it oc'd to 3.8ghz, I also am not using stock cooler I have a thermalright ultra 120 extreme with push pull config in an antec 900 case. My ram is running slightly underclocked at 1900Mhz and yeah, do you think I could push the speed higher on my 920?

Yup all stable.

hey stevo, i have i7 920 at 3.88 c0 stepping tested and all is ok, your D0 stepping should do 4.1-4.5 no probs

Core temp says that it gets to 70 degrees under load, but i dnt know bout that program for temp monitoring, any1 else no anything better? I don't trust it cause the heat out the back of my case isn't even hot really. only slightly above room temp. I don't oc much so i dnt know if this is normal, i do have alot of airflow but surely if it was at 70 the cooler should be making it cooler and producing alot of hot air that oviously isn't going anywhere if it is. well thats my thoughts anyway.

Realtemp <-- free temp monitoring program, and CPU-Z and GPU-Z all work good, i usually just use realtemp for my temperatures, imo for an i7 anything under 90 degrees is perfect =D my 3.88Ghz gets about 60-70 degrees underload, cant seem to find it stable @ 4Ghz or higher....so im stuck with 3.88Ghz, i only get a BSOD when trying to OC to 4Ghz running the stress test, it goes to about 64 degrees then BSODs not sure why it might be doing that tho.

I herd that you don't want it over 70 degrees. But anyway i'll try and get it higher. =D

lol 70 degrees? stock cooler cant keep under that while stressing

Yeah i'm pretty happy with 3.8ghz, its prtty fast. and virt when you said stock coolers can't keep it under that while stressing did you mean not oc'd?

My C0 i7 took a lot of volts to get it stable @ 4ghz and above which ment it would run to hot at 100% load for air coolers. The D0 i have now takes a shit load less volts but it runs hotter at idle but don't get much hotter when under load and it will OC much higher. Best so far is 220 on the BCLK stable with 12x multi, and 4600mhz @ 21x multi. This is with a Big h20 setup though, as for air i think 4ghz is the safe limit as any thing over 75c under normal load ie gaming is to hot for this chip to last. 80-85c is ok for a short stability or vantage test though.

hey arny, for your C0 stepping, do you know ur voltages for 4Ghz? i cant seem to get it stable, keeps doing a BSOD when stressing, so far ive got it at 3.88Ghz 100% stable. i wanted 4 or 4.5 lol is that asking too much?

Mate i can't recall the volts i used on the C0 but i think it was up around the 1.45 mark. and yer 4.5 is asking to much of that air cooler and C0 chip. Also try dropping your multi to 20 or 19 and upping your BCLK to get to 4ghz. The best way to fined out how high you chip will OC, is to lower the multi to 12x and fined the highest
BCLK you can get stable, this will tell you if your chip will make it to 4.5g or not.

k thanks for that ill be trying it. now to OC my gpu =p
