:help: Hi all,
I currently own a BFG 9800GTX and have some questions regarding the physics acceleration.
Can I use a different card other than the 9800GTX that i have just to do physics and if so, what graphics card would be better?
Is there a model like 8600 gt or 8800 gt etc etc etc...that would be recommended to do just physics? I'm a little lost and don't want to spend a lot of money in a new card just to do physics. :)
Thanks in advance and have a great day!!:punk:
I believe that you can use any 8xxx series Nvidia card for PhysX. Personally I would recommend either a 8800GT ( If you can find one I believe that they are EOL ) or a 9800GT.
NCIX.com - Buy EVGA E-GEFORCE 9800GT Superclocked 650MHZ 512MB 1.9GHZ 256BIT DDR3 Dual DVI-I HDTV Out Video Card - 512-P3-N976-AR In Canada. - EVGA 9800GT Superclocked - 163.00 after $10 Mail In Rebate
That will do ya.
Somebody should explain the benefit behind having a dedicated PhysX card & what it does exactly also as I'm even abit stumped by it myself haha. I will be getting new cards soon & may just get SLI while keeping one of my 8800GTX for a dedicated PhysX but I'd like to know more or if that would even be worth it?
Why do you want a dedicated card just for PhysX ? your 9800GTX should be able to handle PhysX and still get decent frame rates in your games - You should give it a try and test for yourself if your rates are decent for you given your resolution and quality settings, you might not even need to spend $$$ for nothing.
I think Nvidia is hyping this Physx so that we will hang on to our older generation cards instead of reselling them to casual gamers. More business for them.
/end conspiracy theory
And apparently any 8 series and up card will work as your dedicated Physx card. I'd be tempted to get an 8500 or something like that.
When I turned off PhsyX my cpu usage on both would usually stay around the 90-100% mark.
So no PhysX is not a marketing ploy and I'm sure with a dedicated GPU for PhysX I'd notice better performance out of my card with games.
On a somewhat related note, is anyone aware of any studies showing what benefits Physx the most? i.e. if someone was looking at grabbing a cheap secondary card, which aspects are most important? Shader numbers? Shader speed? Memory speed? Memory capacity? How much would you give up going from a 8800GT to a 8600GT?
