Hack Released to Enable PhysX on Windows 7 with ATI GPU Present\

Source: *techpowerup.com/105329/Hack_Released_to_Enable_PhysX_on_Windows_7_with_ATI_GPU_Present.html

Although having a powerful ATI Radeon GPU aided by a less-powerful NVIDIA GeForce GPU for PhysX was possible on Windows XP, the succeeding Windows Vista restricted this, by making sure two active display drivers couldn't coexist. Windows 7 removed this restriction, but before you could rejoice, NVIDIA quickly released a driver-level code with its 186 series drivers, that disables NVIDIA PhysX altogether when a GPU from another vendor is coexisting and enabled, even an IGP for that matter. If that wasn't bizarre enough, with the latest drivers, you can't even pair an Ageia PhysX PPU card with an ATI Radeon GPU going about its business. To the rescue comes a soft-modder's nifty bit of software that overrides this restriction from NVIDIA's drivers, so you can use dedicated GeForce PhysX cards on machines with ATI Radeon primary GPUs again. The corrective driver patch comes from tech portal NGOHQ.com community member GenL.

Gigabyte HD 5770 listed, pictured

It looks like a proper dual-slot card. It sports a good looking, massive enclosure for the heatsink and rather sizable fan, and the PCB doesn't look small, either. At the rear, it packs two DVIs, HDMI and DisplayPort, as well as an exhaust vent. It seems all HD 5700 series cards will feature DisplayPort.

Pics and more

^^ what do u think will be the price of 5770 and 5750 in india ? will 5750 compete against 4870 ?

you're predictions seem to be very accurate.I would love to hear your view.

 

[desiibond]

hd5770:

sub 10k card ( I think 8k-8.5k would be ideal price)
should be able to compete with GTX260 and HD4870.

HD5750:

ideal price: 6k
should be able to compete with HD4770 and 9800GT

 

[spikygv]

^^ really ?

5770 is set to be launched at 199$ .. if this is to compete with radeon 4870 which is probably selling around 140$ i doubt people from other countries will buy it. ..

ofcourse , it will be ideal for us indians.

 

[desiibond]

^^ I thought it's going to retail under or around $150. $199 won't be the price for this given that HD4890 is available for $190 (also newegg is giving another $15 mail-in rebate).

 

[spikygv]

my bad. .i wonder if 5770 will be better than 4870. the leaked 3d mark scores dont look too good.. i hope its because of bad drivers.

 

[topgear]

^^ Or it could be that 3DMark06 is now a outdated app to benchmark DX10 and Dx11GPs. For DX10 and DX11 gpu's you can trust 3DMark Vantage results.

3DMark06 is now a nice CPU benchmarking app as it scales well with CPu's

 

[desiibond]

^^3dMark Vantage showed that HD5770 lagged behind HD4890 by a good margin.

HD5770 is meant to replace the HD4870.
HD5850 is the one which replaces HD4890.

 

[comp@ddict]

HD5750 and HD5770 are more like 100-150$ and not 199$ price range...

 

[MetalheadGautham]

HD5750 and HD5770 are more like 100-150$ and not 199$ price range...

Well, they will reach that range after stock of 55nm GPUs clears first.

 

[comp@ddict]

yea...and I guess prices will also come down as GDDR5 will get cheaper(obviously, looks like AMD will use GDDR5 for HD5800, HD5700 and maybe HD5600 series too...)

^^3dMark Vantage showed that HD5770 lagged behind HD4890 by a good margin.

HD4890 is superior than HD5770. Look at the ATI naming convention...The first digit denotes generation, and the second digit the performance series and so on...So 4890 is superior than 5770, even thou it belongs to the next generation.

 

[comp@ddict]

yeah...but later a highly OCed HD5790 may appear and beat the HD4890/GTX260 in performance....

 

[j1n M@tt]

ya...that is possible. HD5xxx series is 40nm, so we will be seeing higher GPU and mem clocks

 

[comp@ddict]

^^^^With the ASUS voltage tweak feature HD5700 as well as HD5800 crds clock at 1GHz + on stock cooling...

 

[desiibond]

All that I hope is that ATI won't bombard market with too many models. three below 5k, two between 6k and 10k, 2 between 11k and 15k and three above 15k should be good and healthy.

 

[Krow]

^+1. There should be a good differentiation between the 4xxx and the 5xxx series. Now it's confusing.
