peak power is 180W to be safe but i read the normal power it really takes is around 145W during gameplay
"According to Nvidia, at peak usage, the 8800 GTX draws about 180W. At normal, heavy use (during gameplay, for example) power draw is about 145W. Idle power is well down in the range of the 7900 GTX's idle power draw."

Hi everybody,
I am new to this forum I am also very interested about upgrading my Mac Pro with a nvidia 8800.
I found this link about an expansion slot utility but I can't find it at the indicated location.
http://docs.info.apple.com/article.html?artnum=304122
I am quiet new on os x so I might miss something basic here.
Anyway I thought this might help regarding an eariler discussion that came up about the slots

simply click on macintosh hd. (not in your users folder)
Then click on the 'system' folder
Then click on the 'library' folder
Then click on the 'core services' folder (should have an X on it)
Then Expansion Slot Utility should be listed with a generic Application icon. Double click on it to load the utility...
Thanks, I looked inside that folder and I do not have that utility ... Is there a way to additional install it ?
yes ... sure ... that was what convinced me to start converting to osx ... having windows as a safety net
so i got my BFG 8800 GTX today! woot woot!
here are some pics....
comparison to the Apple 7300 stock vid card for the mac pro!
i'm still waiting for my order from welovemacs.com for the power cables but for now it have it hooked up the ghetto way all being powered up from the 2 cd drive power
ive tried to get OSx going but like wgrooves with no success .. ive updated my firmware to the newest one.. and still no go...
ive tried leaving the 7300 in there the system wont' boot up.. so the only way is swapping the card out to run osx..
i'll update when i get my powercables form welovemacs.. and see if that changes anything,,,
but i'm VERY happy with this card! omg the power! hahaha
it's not that noisy for thoes of you that curious.. the card is HUGE! as you can tell form the pics
also i did some benchmarks
i have a 3ghz mac pro with 2gb of ram.. 3dmark06 score of about 12k!
i got i think around 2-3k with the 7300!!

The artwork on the card's heat/RF shield is pretty cool - presumably depicting a person who has tried to get the card to work under OS X but only been able to pull out all his hair.
ive tried out..tombraider lengends.. BF2142.. ghost reacon advance warfare.. oblivion.. nfs carbon.. all work perfectly.. all at 1900x1200 or whatever max rez i can get at full max out settings...all work flawlessly with no lag whatsoever
ive been trying to get splinter cell double agent to work thought
but unfortunetly theres a bug or soemthing if you have a 8800 running that game casue i get all messed up geometry and textures are all flickering and artifacting
so jsut waiting for it for them to come out with a patch
and can't wait for hellgate london to come out as it's one of the first DX10 game to come out!

yea theres always one newer coming out bigger and better
but right now i'm pretty happy with it i did push the card thought to the max
playing Fear extraction point
with everything at max and rez at max
went into this chruch with like 10 guards so i decide to throw 5 grenades in there and blew everything up while shooting everyone
with all the particles and wood benches breaking apart and the cement pilar breaking also and bullets flying with bullet shells flying out of my gun
it finially lagged a tiny bit! haha

hi aiongiant,
im really impressed by your modification. For my study research i`m interested in PCIe readback/download performance with this hardware setup. If it's possible you could bench it for me with the tests from Stanford http://graphics.stanford.edu/projects/gpubench/. Just download the binaries and start the test for readback and download from the cmd in Win XP.
This would be a great help for me.
Thanx
Nic

Thanks for awnsering so quick. You have done it right, the values you have posted is the readback performance (data transfer GPU->RAM) of the 8800. For
Fixed Hostmem GL_BGRA Mpix/sec: 261.71 MB/sec: 998.33
Float Hostmem GL_RGBA Mpix/sec: 68.39 MB/sec: 1043.47
the card performs well, but the other values are a little dissapointing (and irrelevant ).
Maybe you can post the benchmark for the "download" (transfer RAM->GPU) test too.
Nevertheless THANK YOU for posting, it is a great help.

heres the stuff for the "download"
(* Download Bandwidth *)
(* GeForce 8800 GTX/PCI/SSE2 *)
(* MB MB/sec *)
(* 512 x 512 *)
4.00 809.91
dunno if thats good or not hehe
as for the results maybe it's not performing as well as a actual pc? no idea nothing to compare it to

scores have improved!
