IS the 8800 GTS 320 any good for Physx? plan to pair it with a GTX 275 OC and was going to move it down for Physx. Is it ok for that or am I waisting my time?? I7 920 is the CPU
 
It'll work, but the old G80 core on the 8800GTS 320mb isn't hugely optimized for CUDA and PhysX. I remember it scoring relatively low as a dedicated PhysX card when compared against its pure-rendering performance.

You'll have to benchmark with and without it to see what kind of difference it's making.
 
yeah i will do but just curious if is a waste of time or not. eventually the GTX 275 OC will move down there and that'll be cool but for now was wondering if the old 8800GTS 320 would do the trick or is it dumb to event try.
 
its just not even worth trying.. you may see some improvement but its not enough to even bother with the extra power usage and heat.. the G80's never got full cuda support.. the G92 gpu was the first true 100% cuda gpu.. its why the G80 even to this day only supports mpeg2 and VC1 hardware accel while all the other chips from the g92 and on support both plus h264 and xvid hardware accel.. but thats just the tip of the iceburg when it comes to cuda support..

but even at that ya might as well test it out first like Unknown-One said.. either it helps or it doesnt.. and it only takes about 20 minutes to test it.. just run 3dmark vantage or something since it has cuda support with out the card in then run it with it in.. or if you have a game that supports cuda try playing that for a while and benchmark the frame rates running fraps and see if theres an improvement..
 
I can tell you that the 8800GTS 640 allowed me to play through Batman AA at 1920 with physx turned to high. Unsure if you'd get better performance while using it as a dedicated card with a Nvidia primary though; I was running the 5850 as a primary card.

no way they recommend a gtx 260 for high dude :rolleyes:
 
So then it's a waste? I have the 320mb gts. I can eBay it I guess. Think the 275OC can handle physx in batmanAA Or crysis warhead at 1900x1200 decent settings and do physx. Or would a dedicated card even though weak, would help.
 
its probably a waste.. but you have the card.. cant hurt to try it first.. we're just giving our opinion so you know what to expect when you try it.. its not like its a hard thing to do.. all you have to do is plug the card into the system and boom you have a physX card.. takes what 5 minutes tops to install and boot up and maybe 15-20 minutes to test it out on some games..
 
Last time I checked an overclocked G80 GTS 640 will run with a GTS 250.
Only thing that really hurt them was the lowly clock speeds and locked shaders. But that has been fixed.

Bump its clocks and I'm sure it will hold its own. And yes its bummer that the g80's didn't get full support.

I'm gonna keep mine for another year or so until I got the cash for 3 24" ips monitors for eyefinity. i7 setup in shipping woot.

The GTS250 is as fast as an 8800GTX / Ultra. I don't know anyone who's managed to overclock an 8800GTS 640 far enough to get it up to those speeds.

It will hold its own at rendering. PhysX and CUDA performance on the G80 core will still be dismal, especially trying to run graphics and PhysX at the same time :eek:
 
8800gts would be dedicated physx.

What would be a good cheap card for physx? I have gtx 275 for rendering
 
In order from slowest to fastest: 9600GT, 8800GT, 9800GT, 9800GTX, GTS250.

If you're pairing it with a GTX275, I would go with a 9800GT (a low power version so it doesn't need its own 6-pin).
