Hi, so i just picked up a brand new BFG 9800GT card http://www.amazon.com/BFG-BFGE981024GTGE-GeForce-Graphi... for only $30 (craigslist of course) and I was originally planning on using it as a physx card in my setup. Dont comment on how physx is worthless and stuff ive seen the arguments, but for 30, what the heck. I want to make sure that I will be able to run this card, along with my 570, safely on my PSU http://www.newegg.com/Product/Product.aspx?Item=N82E168... . My other specs are in my signature. If not I have another computer I could put it in, its an HP prebuilt that I used to use and now my sister is using and it would give it a big graphics boost, not that anyone games much on it. What do you think? Safe to use or should I toss it in another computer?Thanks!

I dont think the 9800GT and the GTX 570 could be powered by a 600w, you'd be stressing it way too much, I say just toss it in you sisters computer.

Also, seeing how its an HP, it might not have enough power on the PSU for the 9800GT.

Hoped this helped!

Well I used to use the hp with a 4670. Neither of those required the power connecters so I'm pretty sure it could handle the 9800 also. Why would be the risk of running it in my comp? Maybe just to see how much performance increases. I haven't had any problems with the power so far.

If your getting a 570 GTX, why do you need a physx second??

Its not necessarily that I need it, but its only $30. I already have the 570 by the way, it does have some problems in physics benchmarks and related games. Nothing huge but I figured for only 30 dollars why not?

does your motherboard have two 16x lanes? bc if by populating the second lane with your physx card you might loose a bit of performance on the 570 at 8x

No, the 570 is running at 16x but the other lane is only 4x. Now ive read some things that say that the physx card will actually slow down the performance of the main card. I dont see why this would be the case as it shouldnt even be in use except during physx stuff. How would it hold back my 570?

if the 9800 at 4x is slower at doing physx versus your 570 doing both physx and graphics then having the 570 + 9800 will actually end up being slower.

You won't really know until you try it out though

Ok, sounds like it would just be better to put it in my sisters computer so when friends come over they can use it for gaming. Thanks for the advice, $30 for the 3.3 to 6.9 WEi graphics upgrade should work out nicely.

no problem... that would be what I would recommend as well

yeah honestly my single 570 runs physx just fine on my rig, Id put the 9800 in a different system for a nice low/mid range gaming machine

false; 4x is more than enough for a dedicated physx card, it should bring minimum fps up when taking the load off the gtx 570

Where do you see that I made a claim, I was just explaining to him how a 570 pair with a 9800gt at 4x could POSSIBLY be slower, I didnt claim it was actually slower.

What I said is true.... if the 9800gt is slower at doing physx than the 570 alone then the combination WILL end up being slower. It will also differ from game to game depending on how much physx the game requires, some games which have only a light amount of physx I am GUESSING will be faster with the 9800 because it wont limit the 570. Other games with heavy amounts of physx MIGHT be limited by a 9800 running at 4x, and as a result the combo would be slower.

ok im telling you though that is not the case, you are not understanding how physx works in terms of loads in the two concerned gpus and I dont feel like getting into the details, so yeah oh well, your right, whatever

alright god... then ill accept everything you say without an ounce of explanation or evidence... to be useful in this world you have to back up what you're saying otherwise it's not worth anything.

Nothing I said was a claim, just a possible explanation as to how a combination of two things could be slower than one thing alone, ie. if you study chemistry its like a rate determining step.

Now please enlighten me on how physx REALLY works as until now I haven't said how it works but only gave a hypothetical explanation.

PhysX sucks to be honest with you, I use it on one game; Batman AA. If you want to berate me for giving quality advice for free that is not up to your par, have fun! I am a graduate student and do plenty of writing as it is so regurgitation is not what I want to be doing at the moment. Furthermore, you are not the OP; settle down there little boy.
