Nah, want to keep the option open to add an nVIDIA card for PhysX while keeping my other slots and all USB ports and all working.

Just found Asus 990fx sabertooth is below 11390/- at IT Depot. If only the FX8150 was a bit better. :(

Doesn't want to face these:

Gaming is where the Sandy Bridge architecture most easily proves that you don't need a thousand-dollar processor to turn in the best frame rates, and that's in spite of the 16 lanes built into each CPU's die. We've even seen situations where an NF200 bridge soldered down onto a Sandy Bridge-based motherboard enables performance just as compelling as a high-end LGA 1366 configuration. The thing is, a Z68 or P67 platform's 24 total PCIe 2.0 lanes aren't explicitly set aside for graphics cards. They have to handle every device attaching via PCI Express, including network and storage controllers.

We’ve even tested a few "enthusiast-class" Sandy Bridge-based motherboards so loaded with features that simply installing an add-in card forced certain slots or on-board controllers to become disabled. That doesn’t sound like a solution a power user would willingly accept to us.

(From Toms Hardware)


Each of the two MSI mainboards has three graphics slots that work in the same modes. A single graphics card installed into the top slot will work in full-speed PCIe 2.0 x16 mode. If two graphics cards are in use, the graphics slots are x8 each. The third graphics slot has four PCI Express lanes, but if it's occupied, the following becomes unavailable: the eSATA and the additional SATA port, the onboard USB 3.0 connector, both PCI slots, and the back-panel IEEE1394 (FireWire) port.

Neither I can find one. Suddenly BD just looking plain VFM if I ignore the fact that it will actually held back the cards to perform at its full potential. :(

Skud - Dude.. Really? 2cards?? 1 for physx?? cant u just upgrade to i7 2600K & OC to 4GHz and offload PhysX to CPU?? 2600k is more than any1 can need anyway...!!

MegaMind - New XFX 6950 1GB - 10,600/-(in chennai) - Mayne thats a sweet deal!! :O

PhysX can only be run on a nVidia card.

@lionking:

Wanna experiment. ;) And this link may be helpful for understanding why no CPU PhysX, although the CPU used was a i7 920:-

tkin - hey dude.. how r u?? :) This is Anant from Indore.. we met at Asus meet in bombay.. :)

and supposedly physx is also capable of running on cpu.. :p earlier i also thought it was on nvidia cards only... :p

Skud - Experimentation is highly promoted sir!! :D :)
went thru that link almost a year back dudeeeeeeeeee...

Yep, 6950 1GB

I did a test on physX..
I haven't posted the results for i5 2500K for physX, but i did test it & the particles and shatters(on i5 2500K for physX) weren't good enough as opposed to nvidia 8600gt set for PhysX..

MegaMind - 1st of all - Sweet Rig Bro!! ;)

@Particles & Shatters werent good enough vs 8600GT??? :O :O :O Weird stuff dude... anyways.. me lappy outta battery.. so gn all.. :)

No, you can't run "PhysX" properly. Physics you can. :p

here's what nVideahh does. Decides to use X87 for PhysX on GPU. CPU makers phased X87 out in favour of SSE 12 years ago. So, CPUs obviously run X87 code slow (+ nVidia forced to only run off a single core) and nVideahhh claims "OMFG OUR GPU PHYSICS I.E. NVIDEAHHH PHYSX RUNS SO PHASHHT ON OVAR CUDA ACCELERATED GHEE-PEE-YOUS :cool:" :mrgreen:

Then with PhysX SDK 3.0 (this year), they start supporting CPUs (+ multiple cores). Guess what, they use SSE instructions for running "PhysX" code on CPU. Why not use X87 again? :rolleyes: :mrgreen:

Battlefield 3's physics pwns pretty much everything without these marketing gimmicks.

I don't give two sh!ts about what non-sense the marketing of these companies says. As someone who prefers real standards over propreitary sh1te, I'd say let sense prevail over idiocity.

Again the PhysX discussion! I think in past I have explained it ...lost count how many times.
As ico said, PhysX is just a marketing gimmick by Nvidia...It is just a nice add-on but can't be any deciding factor. All the sites like Tomshardware, Guru3d, Anandtech have came to the same conclusion; it is not at all anything extra ordinary and at best it is just an Add-on feature.

Anant, buddy how are you? Remember we also met over the Asus meet-up.
