Im leaning towards an EVGA 8800GS Superclocked, thanks to the answers i got from a previous thread on here, and I'm wondering if my current PSU with 18W on the 12v rail can hang with an 8800GS. It handles my 110nm X800XL AGP fine, so I'm thinking, what with the 8800GS being a 65nm part, it should be ok right?

I just gave a customer a bigger PSU because I didn't want to put an 8800GS in with his 3+ year old (18 amp 12v) Antec Smartpower 400W. It may have worked, I just didn't want a tech call because of instability. So, you may be fine if the system isn't that loaded. The 8800GS uses a little more power than the X800XL, but another concern is if you are going from AGP to PCI-e are your system specs changing? That in itself could consume more 12v to where even an X800XL PCI-e would be too much draw.

18 amps is wimpy by todays standard. If you have issues, you don't have to spend a fortune. Look at the Seasonic made Antec Earthwatts 380W with 27 amp on the 12v for just $30 shipped AR: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

i dont know if you would have heard of it cos i live in the Philippines, but its a Spartan 450W (before that, I was using an old 350W, but it was causing problems). I'd only be changing the mobo and the videocard, everything else is kept. (2x80Gb PATA, 2x512mb DDR2, A64 3500+ Am2) Thanks!

Agreed. I would have thought that 18a is a bit low to power the 8800GS.

Hows your 8800GS performance-wise? Havent seen anyone else on here who actually owns one
March 27, 2008 1:23:10 AM

It's not here yet :( 

Should be arriving on Friday. I just moved from 8600gts on a 19" LCD so this would double my frame rates.

Do you have the EVGA version? All the EVGA version comes with 1 ns memory and quite fan. Good for 2000+mhz when you overclock. It should go toe to toe with 9600gt easily.

I own an XFX 8800GS. It's pretty incredible for the price. To be honest I thinks it's the best bang for the buck now in the USA at $110 shipped. I have not yet done a major comparison yet, but I'd say it challenges the 8800GTS 320MB at stock speeds. Haven't OC'ed it yet due to lack of free time.

I also tweaked games for the customer after putting in this same card. AT his native resolution of 12x10. I was able to crank all his games to max details with 2x-4xaa and 8xaf. Games included the orange box, BF2, NFS:Carbon and Most wanted, COD4, Flatout 2, Farcry, and UT2003. Of those cod4 stressed it the most.

And yes, as Marvelous has said, the evga is the better buy. It wasn't around here when I bought mine, but for sure priced the same take the evga with the variable speed fan and higher mem clocks. If the evga disappeared I'd still recommend the XFX for the price too.

Hey Marv, enjoy the new card and let us know how this one OC's for ya. With that fan, No more need for 7v's :)

Will do. :)  I can finally replay Crysis @ high settings. :sol: 
March 27, 2008 3:09:50 AM

Here's a good article on 8800gs and it's memory usage.

http://www.digital-daily.com/video/asus_en8800gs/index3...


That is Crysis @ 1600x1200 and vram usage.

Seems to me crysis will be limited to 1600x1200 or 1280x1024 2xAA and so on. This isn't a problem for me since I'm on 19" LCD and not upgrading anytime soon. Not that 8800gs has enough power to play other than 1280x1024 high settings anyway.

I was about to get the 9600gt for $20 more but decided not to. I like the 96 SP and huge texture fillrate it has over 9600gt. Combined with 1ns memory and overclock it will scream harder in lower resolutions and future shader intensive games.

Whenever my 8800gs breaks evga would surely replace it with a 9600gt anyway since 8800gs is only limited stock. :kaola:  :lol:

i just saw a the eVGA 8800 GTS 320mb on Newegg for ~$115! im sorely tempted. but i guess its just too much GPU for 1152x864 (max game res for my monitor) isnt it? but for only $5 over the 8800GS hmmm... and i'd have to say goodbye to a pci slot...
March 27, 2008 10:32:05 AM

8800gs is the better buy now.

8800gts 320 might have the memory bandwidth to do AA but that is a 320meg card which would be the biggest limiting factor.

8800gts
GPU: G80
Interface: PCI-E x16
Core Clock: 500 MHz
Shader Clock: 1200 MHz
Memory Clock: 800 MHz (1600 DDR)
Memory Bandwidth: 64 GB/sec
FLOPS: 115200 GFLOPS
Pixel Fill Rate: 10000 MPixels/sec
Texture Fill Rate: 12000 MTexels/sec

8800gs
GPU: G92
Interface: PCI-E 2.0 x16
Core Clock: 550 MHz
Shader Clock: 1375 MHz
Memory Clock: 800 MHz (1600 DDR)
Memory Bandwidth: 38.4 GB/sec
FLOPS: 132000 GFLOPS
Pixel Fill Rate: 6600 MPixels/sec
Texture Fill Rate: 26400 MTexels/sec

Thing about 8800gs is the highly overclockable.

Usually 680/2000 at these clock rates 8800gs has the advantage and 64mb extra video ram would surely help.


Core Clock: 680 MHz
Shader Clock: 1505 MHz
Memory Clock: 1000 MHz (2000 DDR)
Memory Bandwidth: 48 GB/sec
FLOPS: 144480 GFLOPS
Pixel Fill Rate: 8160 MPixels/sec
Texture Fill Rate: 32640 MTexels/sec

notice the massive texture fillrate it has over 8800gts. Everything else is so close. 8800gs packs a more punch than 8800gts 320.

Thanks for the 8800GS article. Seems like you researched well before buying.

Having both cards, I must admit I like the 8800GTS 320MB for $115. At stock it's a little better than my 8800GS from what minor testing I have done. But they seem very close and I hope to properly compare them head to head to see if that holds true or not. Maybe overclocking makes the 8800GS better like you say. But on the other hand, I really value the quiet GTS dual slot rear venting cooler. To me, It's much better than my 8800GS cooler, or even the refernence style 8800GT cooler too. And that would push me over to the GTS 320 if deciding between the two.

Anyway, I see both as great buys and couldn't fault anyone for going with either.

Maybe the xfx cooler sucks but the EVGA is quietest video card out there in the market. Biggest bottleneck is the memory bandwidth on the XFX 8800gs with 1.4 ns chips. EVGA cures all that with better heatsink and 1ns memory chips.

When I get my card this friday I'll post some benches for you to compare. :) 
March 27, 2008 1:12:41 PM

Here's some more benches where shader and or texture fillrate matters a little more than memory bandwidth alone. Where 8800gs shines over 9600gt.

daym marv. u really like ur 8800GS :p  no reason why i shouldn't like mine as much when i get it, right? cos now im sold on the GS. wonder if we can convince mr. grapeape to put it up on the "best cards for the money" article?

Yep, the 8800GS is an excellent card for the money at the mo.
Can't see it being put in the 'Best Cards for the money' article as it is only in limited supply. Now the 9600GT is fully released expect supplies to dry up and prices to rise.

No just putting things in perspective. I like what I see from the card that is why I purchased. I don't even have it yet. :lol:  Should be here tomorrow.

For the price you can't go wrong with how much performance it offers.

I highly doubt that, even ignoring the silent passive cards. There is something wrong with their charts. I think the test system was an open bench rig out in an unheated garage in February. ;)  Poll reference 8800GT owners to see if they think their cards run 24 decibles under load when gaming. Without locking up anyway.

Isn't the evga 8800GS cooler the exact same cooler that is on the reference 8800GT? It sure looks like it. Those can be fairly quiet, at factory 29% fan speed. But then they run very hot. And if they do ramp up, or you choose to ramp them up, then they are loud as can be. Just look at some 8800GT reviews they said the cards were quiet. Problem was that was 88 degrees and 29% fan speed in an open system. Other reviews said they were loud because their cards ramped up. That chart of yours shows 24 decibles at load for an 8800GT?????? That seems wrong or greatly misleading. I hated that cooler and yanked both of mine for much cooler & quieter Zalman VF900's. I found mine kicked up a notch higher/louder for crysis and cod4, and also got up to 92 degrees.

Now, if the same cooler, it Probably would not be as hot on the GS, but still you are not going to get low temps and low noise out of that cooler. The two slot design of the GTS is way better IMO if you factor in noise/performance/and even rear venting.

I will say, I'd take the variable speed evga fan over the XFX 8800GS 100% fan. But, if I had to compare the two, my 8800GT was louder at 65% than the XFX 8800GS at 100%. At 100%, the 8800GT is just plain obnoxious, 70% and above is terrible IMO. If the evga uses that 8800GT fan, it's honestly far from a nice cooler. I fear you may be greatly dissapointed if you expect to OC that card and have a quiet fan like in that review. Hopefully I am wrong.


Alright, thought I'd post an update. After studying pics, it seems the evga 8800GS is indeed the rev 2 8800GT cooler with the slightly larger fan than the original 8800GT fan still on most cards. It is quieter, and nicer for sure, but still not quiet if ramped up. Good thing is, you may find overclocking at 60% fan speed cools as good as th old cooler at 80%.
March 27, 2008 10:45:50 PM

Techpowerup had no heat issues clocking it up to 700mhz with stock cooling. I don't know why you think they don't know how to measure noise coming out of the fan. It's a whole lot better than xfx dinky small heatsink with a hair dryer fan that can't be controlled. :lol:  Brings back memories of the delta fan craze.

EVGA 8800gs is based on 8800gt reference cooler but has disabled? less rops, SP, 64bit memory controller and chips taken out. 8800gs consumes less wattage = less heat and runs cooler than a 8800gt. 8800gs consumes same wattage as a 9600gt or 3850 if you haven't looked at charts yet.





Edit: How about I give a mini review with overclock and factory settings benchmarking WIC, Crysis, Unreal 3, 3dmark, cooling, heat etc with my crappy english skills. I'll work on it this weekend and post a article early next week. Now I don't have a db reader or anything but I'll try to be honest review about it.

I'd actually like to see you do that and totally trust you'd be honest about the findings. That would be great. Also, compare it to your 8600GTS noise and temp wise. And try ramping up the 8800GS fan with ntune, and you'll probably hear it gets quite loud. Please share your findings, that's why we are here IMO. Just so you know, I am not against that card at all and actually have one on order myself.

Yes, I understand why the 8800GS would be quieter/cooler on the same fan. With the new style 8800GT cooler, I can see it beeing better than my 8800GT was for sure. I was thinking it was the original 8800GT cooler which IMO is pure crap. But I still question their results because I have heard so many of these cards first hand. 20db is downright hard to measure as ambient room levels are typically much higher. Their <20db ambient is pretty amazing, so they have a serious sound testing lab. Look at X-bits testing in comparison. http://www.xbitlabs.com/articles/video/display/leadtek-...

Th XFX 8800GS is the same cooler on the XFX 8800GT and it too has the larger diameter fan compared to the orignial 8800GT. So it's no screaming delta. I don't have auto fan conrol, but as you know from your 8600GTS, there are ways around that. My XFX is very quiet with a homemade harness and zalman fanmate running full time at about 8-9 volts. But at stock 100% it's like my 8800GT at I'd guess about 60% or so.

Would the eVGA's fanspeed be controllable through nTune/Rivatuner a la ATi Tray Tools? i purposely underclock my videocard (is this safe btw?) when not gaming and set the fan to a low speed. then when i game i set back it back to default clocks and default speeds.

Yes it can be controllable.
March 28, 2008 1:36:34 AM



Despite the massive overclocking, the card was running at acceptable temperatures at all times - and it was whisper quiet. The perfect combination in my opinion.


That's the loaded temps from Techpowerup.

Yeah I'll give a whirl. I'm actually put some time into the mini-review. So stay tuned. :wahoo: 
March 28, 2008 6:11:49 AM

Looking forward to it marv. maybe ill hold off gettin my own GS till i see your review. Any experience with EVGA's rebates?
