GTX 580 SLI + GTX 295 as PhysX ?

Good thread, answered some of my questions I was having. My brother runs 8800 in SLI right now and is looking to upgrade.

So if I go with an ATI card using one of those to do the PhysX would be an improvement, however if I got with a 580 then it would be better to simply run the 580 by itself.

Have there been any reviews of games running on the 580 with and without PhysX that show the difference in performance?

I unfortunately can't see images on most image hosting sites as they are blocked where I am, so if it was already linked above I apologize.

what 8800 are you talking about?
 
I want to say they are 8800GT cards. Significant difference I suppose from the GT variant and the GTX cards. I'm trying to ask him now though to find out for sure which ones they are.


*Edit: He states they are 8800GTX cards*

3 or 4 580s? This is insane...are you going to to get 120 hz monitors and shoot for 120 fps?

Your 120 hz monitor got me interested and I looked around but there seem to be no 24" monitor that is 120hz (?).

And, I'm going for the best graphics solution for my new rig which is an absolute monster! 😀

I'd sell the gtx295, sell the Dell 2405FPW monitor, and get a better monitor! That Dell will be laggy with 2 gtx580s. A better monitor will give you a much better gaming and more bang-for-the-bucks computing experience

Yea, I'm definitely selling the GTX 295. I might keep the Dell for another system but I may sell it as well. What does the 2405FPW go for nowadays? It's in perfect condition with no dead pixels.

What monitors do you recommend? I'm considering the Dell U3011 UltraSharp or two more Samsung T260s to go with my current T260 for a 3 monitor setup.

I think I saw some 23 inches with 120 hz...but I admit I wasn't paying too much attention since I can't afford them.

I see...

Yea I think I'll stick with larger format 60Hz monitors for now. I don't give a rat's ass about 3D but I want surround gaming. So the solution is either two Samsung T260s (I have one now along with the Dell 2405WFP) and a Dell U3011 in the middle (30" monitor) or all three Samsung T260s.

Plus, I have the Asus P6T7 WS motherboard which allows Quad SLI I believe.

its not a penalty. the 5870 cant do any physx at all so even a fairly moderate card is useful for offloading physx to while letting the 5870 handle graphics.

Let me get this straight -having a nvidia card to do physics would benefit fps ONLY in games that use physx or in ALL games that use physics??

I have a gtx 8800 ultra I'm thinking of dusting off if the latter is true.

Are you doing just air-cooling for your setup? Air cooled 4.1GHz is pretty darn good. Of course, you have the 980X which is a beast. I'm getting the 990X as soon as it comes out!
Click to expand...

Yes, air cooled. Currently run at 4080MHz with 1.3V since I can run my memory at 2040 with a 170MHz bus. Normal temps at full load with LinX and Prime95 are in the mid 70s. Spikes to 80 at times. Any more voltage and clock speed and it spikes into the 90s.

Just games that are using PhysX, not just physics in general like Havoc or something.

To be very specific hardware accelerated PhysX. Just because a game uses PhysX as it's physics engine doesn't mean it's automatically GPU accelerated. Only a handful of games are coded for this right now.
 
I noticed in the Nvidia Control Panel that the second GPU in my GTX 295 is assigned to be a "dedicated PhysX" processor. There is an option for me to assign the PhysX to the CPU (?). Is this something I should do? What are the pros/cons of doing this?

I would like to dedicate both by GPUs for graphics instead of one just for PhysX.
