Ati & nvidia?

I recently bought the HD 5970...i noticed on another user they had also the hd 5970 but they had a older nvidia card for physx how would that work? i have an older 8800gtx from my old comp. so i was wondering if could do the same thing as him?

thoughts?:confused::good:
 
i assume you mean me :P

yes you could do it. i have used it for batman arkham asylum and for the mafia ii demo and it works pretty well. also, if you are into folding, it is a great way to get the performance of an nvidia card while having an ati as the main one.

what are your system specs?
 
yeah haha it was you i couldn't figure out how to private message and i didn't want to just post ur name on it lol

i built a pretty diesel machine...

cpu Intel Core i7-980X Extreme Edition Gulftown 3.33GHz LGA 1366 130W Six-Core

graphics card XFX HD-597A-CNB9 Radeon HD 5970 Black Edition 2GB 512 (256 x 2)-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support ...

moboASUS Rampage III Extreme LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

12 gigs corsair dominator ram...

my old video card is an EVGA 320-P2-N815-AR GeForce 8800GTS 320MB 320-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card

so even if my monitor is not plugged into this card it will still use the physx? is there any real benefit to it? i'm pretty sure the radeon hd 5970 blows the 8800gts outta the water no?
 
the 5970 definitely blows it away but the 8800gts won't bottleneck in except for in games when you're running maximum physx at really high resolutions where the 8800gts can't keep up (pretty sure i ran into this problem with mafia ii and my eyefinity setup where the 5970 alone would get much higher frames than with the 8800gt and physx).

as for the monitor, no you don't need a physical monitor but you do need to enable an extended desktop for the card so it thinks it is putting out a resolution to a monitor.

in case you don't know, nvidia has their drivers set so that they won't work with ati cards. for setting it up, on here i'll just say to use the 257.15 drivers since they don't have the ati compatibility problems (nvidia must have forgotten to add that). just check google for the other ways ;) to get the drivers working.

since you already have the card and the hardware (although what power supply do you have?) i'd definitely put the card in and get it set up (easy to take it out and remove drivers too). you got nothing to lose in trying it. if you really like it but find it bottlenecks, then maybe consider upgrading the physx card to something like a gtx 250 which should easily handle any physx work you throw at it.

oh, and you can't pm until 100 posts ;)

thanks a bunch... yeah i'll try out tonight thanks for your help! i'll definitely have to google around.. lol i guess i never kept up with technology and its terms T_T

i feel so old now...
 
btw i have a CORSAIR Professional Series AX1200 1200W power supply i think its enough :)

so just to make sure i'm getting this right... all i need to do is plug in the card... install the drivers and we're good to go? is there really a noticeable difference? i havn't had a chance to play any graphic intensive games yet. still stuck on sc2 lol maybe i'll reinstall mw2... i dunno

thanks for your help!
 
yeah i think that power supply should be able to handle it :P

yep, put the card in, install, restart after they prompt you, and then you have to go into screen resolution, click on detect, select one of the blacked out monitors that belongs to the 8800gts:

try to connect on vga:

extend:

move to another place for convenience. please note that the resolution there is 1280x720 since i do have an actual monitor hooked up to my 8800gt (which you can do as well if you wanted an eyefinity setup and then another one or two monitors). your resolution should probably be 800x600. since you'll be able to move your mouse to the 800x600 "monitor" putting it on the corner like that reduces the chances of you moving your mouse to it:

hey Joh...

sorry i can't pm lol

anyways i have both cards installed and i installed the 257.15 driver

i see under the uninstall that physx is installed ... i currently have two monitors so my 2nd monitor is plugged into the nvida card...and my main monitor is in my 5970... is ther eanything else i need to do? is there a test i can run to see if both cards are running?

thanks for your help!
 
sweet dude! hey no problem.

if you run 3DMark vantage you should get a ridiculously high score for your cpu since vantage takes advantage of the physx and offloads the cpu. seeing as how you already have a 980x, you HAVE to post your scores! :eek:

EDIT: it looks like with ht on at 3.33 you should get around 30k (without physx) with the 980x. so your score should be higher than that after you run vantage if physx is working.

sorry i've been so busy at work lol work sleep work sleep... without a physical monitor there. there is no option to extend it. do i need to connect the two cards together?? i don't think so right ??
 
hey joh.. long time no respond lol sorry but i rebench marked it...
http://service.futuremark.com/home....24642513804D2D?resultId=2503009&resultType=19

still not that good

on the 4th test my computer just lags the one where it does the crash / smoke test... i don't think physx is working... there's gotta be something i'm doing wrong
should the nvidia card be in 1st slot?

btw i'm thinking about getting 480 fermi... just for kicks

btw the drivers MUST be installed right? i tested both fully installed drivers and then just having physx installed... same results both times so i'm guessing my mobo isn't even using the nvidia card? have u benchmarked ur setup?
