GTX 465 For PhysX

[3lackDeath]

My main card is currently the Radeon Gigabyte 7970 OC but i also want an nvidia card to be used for PhysX purposes.

What do you guys think of that card as a dedicated physx card?, my budget for this is under $100, cant remember where but some dude was using a 8800 gtx for physx only and he was happy.

Feel free to give suggestions...

PhysX requires compute power only. Therefore -> Kepler. Much less power consumption than the cards you mentioned and still faster. GT640 would be a good bet. Memory bandwidth is basically irrelevant for PhysX, so the DDR3 version is fine.

I looked at the GT640 and some others but i'm still not sure what i'll be going with so i'm going check around a bit more as there is no rush, thanks for your input though

I thought Kepler has less compute power than Fermi?

On paper they don't, they have more SP GFLOPs. It depends on the workload if they can use that efficiently. The smaller Keplers have smaller caches and less registers than GF110 and GK110, thus in some workloads they are slower. But PhysX shouldn't be one of them.

Get a cheap GTX650. Lower power draw than older cards and will work fine for what you want. Can be had under $100 AR.

Or try and find a cheap used GTX460. More power draw but maybe cheaper. Not sure what they are going for right now.

Interesting. Thanks for the info!

I was lucky enough to get a used GTX 460 on ebay for $80, will do an update when i get it.

Still need to figure out out to run them together...
