Is Physx worth it for me?

post #1 of 34
Thread Starter 
Fellas I upgraded from a 8800gt sc (flash to a 9800gt sc) to a 6950. I've been hearing a lot about physx and I'd like to give it a shot.

I'm a little worry because I only have a 550w PSU and wasn't sure it's enough to run multiple cards.

Question...

Is 550w enough to run a 6950 and 8800gt sc? What performance increase will I be seeing?

BTW my 8800gt will only fit on the x16 lane since I upgraded the fan. Which mean I will have to run my 6950 on PIC-E x8. Will this hindrance my performance?

I think you'd be okay with the x8.

550W PSU may be a little low, but if the build quality is good then I think that would be okay as well. VisionTek recommends 500W for your card alone, 8800 GT TDP is 100W, so it depends. Those are usually overestimates so I think you'll be all right. Worst case your computer just turns off, right?

What games do you currently own/want to own that have physx? Also, your PSU would be close to max draw. So long as you dont OC heavily, you could give it a try and upgrade as soon as possible.

I own Crysis, Civilization V, CODMW2, CSS, HL2, Guild Wars, Dungeon Siege, Warcraft 3, and a few more. I don't think these games run on physx. I'm about to go buy Batman Arkham Asylum in a few minutes but needed confirmation that my PSU is enough before making the purchase.

You are correct, none of those games would benifit from having a physx card.

Batman would, however Physx is purely visual at this point. The game is enjoyable without physx enabled. Adding the extra card, and moving your main GPU around for one game isnt worth it IMO.

I personally have Batman, Metro 2033, Mafia II, Dark Void, and a few other games, I finally decided to add a physx card after months of playing these games and beating most.

PhysX isn't worth it. I have a 9800gt for physx. I had to sacrifice either my sound card or my physx card when I upgraded to Sandy Bridge. It was an easy choice

To be fair, your system isnt comparible to his/ours. Your sig rig is running a phsyx enabled GPU and has the ability to run most games at higher settings with physx enabled. I do agree with your statement though, Id rather have a nice sound card than a dedicated Physx card.

For one game...My answer is no.

I think Imma try it... I want to see the difference b/w phsyx on and off in Batman Arkham. Just like lonewolf said... the worst thing that can happen is my PC not turning on.
