EVGA GeForce GTX 275 co-opts a GTS 250 for PhysX duties
Ready for some more dual-GPU madness, only this time in the resplendent green of NVIDIA? EVGA has gone and concocted a special Halloween edition of the GTX 275, which has sprouted an entire GTS 250 appendage solely for PhysX gruntwork. Dubbed a new form of Hybrid SLI, EVGA's latest combines -- for the first time, from what we can tell -- two different GPUs and assigns them with specific and mutually exclusive tasks. Whether this concept takes off will depend to a large extent on the effectiveness of PhysX acceleration and whether it can show more efficient scaling than regular old SLI with two boards or more conventional dual-GPU setups like the GTX 295. Color us intrigued, either way. P.S. - That's what the actual card will look like, we're not making it up.%Gallery-77092%
ATI teams with Havok for boundless gaming
ATI made some noise today with a pair of announcements regarding their new physics processing technologies. The 3D graphics leader is introducing the CrossFire X1900 multi-GPU solution, which gives gamers a choice of asymmetrical physics configurations -- what ATI has coined "boundless gaming". The setup requires either one or two graphics cards for rendering, and a separate card for physics processing. "Boundless" refers to the open architecture that allows for different cards to be used in each role, so gamers can decide between various high and low end cards to handle each function. ATI maintains an updated list of CrossFire certified components.ATI will also be working more closely with middleware provider Havok to promote the Havok FX SDK. Games that have leveraged the Havok technology include Half-Life 2, Perfect Dark Zero, FEAR, and the Splinter Cell series.See also: ATI's new CrossFire aimed at Athlon gamers Havok vs. AGEIA: the physics/PhysX showdown
