Hello guys i think the title tells it all. so recently i upgraded my system to a gtx 570 sli setup from my old msi gtx 550 ti which i want to add as dedicated physx here is my rig: PSU: Thermaltake toughpower XT 875watt Ram: G.Skill Ripjaws X F3-10666CL9D-8GBXL 8G Kit *2 adds up to 16gig HDD: WDC WD20EARX-00PASB0 with Model ID Patriot Torqx 2 32GB SSD for intel smart response tec. CPU: Intel core i7 2600 clocked at 4.2ghz with a coolermaster v10 to cool it. GRAPHICS: Gigabyte gtx 570, 1280mb gddr5 and Asus Gtx 570 direct cu 2, 1280 gddr5 MOBO: AsRock Z68-Extreme3-Gen3 Intel Z68 USB3.0 1155pin Motherboard CASE: Thermaltake overseer. this is my first ever build so could anyone point out any bottlenecks if their is any?
Everything's fine. You don't need a dedicated Physx card. SLi is enough and anyway there's just a few games that use it.
oh cool but i am gearing up to play the new batman and battlefield 3 and iv seen posts that says the new batman is gonna be heavily physx based? anyway thanks heaps for the reply.
PhysX is unbalancing SLI. Running SLI + PhysX is not that good. Drivers or something is wrong. There are some numbers from my own testing. Asus 1.5gb GTX580, Ref model at 828mhz. Mafia2, maxed, physX high. Single GTX580 PhysX : 45 fps Single GTX580 PhysX second GTX580 : 62 fps SLI GTX580 PhysX gpu#2 : 54 fps SLI GTX580 PhysX gpu#1 : 53 fps My main point is that in 99% of the games there are no Nvidia PhysX so you do have to run SLI .... But if you run Mafia2, Batman or few other "high physX" games, i recommand to run SLI + 3rd GPU on PhysX. If you have few box laying around .... get a 550TI and be happy.
