u might be serevely bottlenecked if you get a high end card with that cpu..btw u mentioned in your first post "There's not a CPU out today that can keep up with the fastest high-end single card GPUs anyway"..that comment smells like bullshit to me..my opty 165 oc'd at 3ghz handles my 1900xtx fine and i have no issues related to performance loss due to cpu limitations

How would you know if you're running into CPU limitation or not?  You're not unless you record your FPS across all resolutions with the same graphical settings.  If you do that and you get about the same FPS in the higher resolutions than the lower, then you know you're CPU cant feed the GPU fast enough to render anymore FPS on any resolution.  You're not gonna notice it because the difference is between 110 FPS and whatever the card can handle with a faster CPU is unoticable to any human.  We can only tell a diff up to 50-60 FPS.  Anything past that looks the same to us  You can OC your opty all you want but you're not gonna notice any difference  between 100 FPS or 110 FPS.  I personally find it pointless to OC any high-end CPU because of this unnoticable performance increase in games.  I played with OCing my 4000+ and got it up to 2.7 stable, but that was just for fun.  It's retarded to keep it there as you're only asking for problems down the road and I didn't notice any diff.

Read their reviews on the 7900 GTX and X1800 XTX and you'll see what I'm talking about in their benchmarks and graphs.

i post at guru3d frequently...as for some limitation testing ive had a fx 60 @ 3.5 on phase change and did alot of testing in oblivion and fear on single card and didnt really notice much diff..however throw in a dfi cfx-3200 dr and a 1900 master card, fps was helped quite alot on high resolutions been on both cpu's...now with 2 cards yielding better fps tells me im not bottlenecked as thats a heck of alot of instructions been sent to both gpu's and it seems to be handling the load just fine.

Well that's a pretty insane OC on that FX-60 since it's stock speed is 2.6 GHZ, so I'm sure that's why you're not seeing any limitation at that core CPU speed.  I'd like to know how you got it that high and kept it stable, in fact I dont think you could as I just read on the new FX-62 at guru3d and they could only get that up to 3.13 stable (on air cooling though).

It's fact that there is CPU limitation with the newest cards though, like I said, read their reviews and you'll see this.

it wasnt exactly what id call stable....dual priming it failed after like 1 hour or something...but it was stable enouph to run all the benchies and produce some results and temps were more than fine...idle at like -20 full load -15-10

Or just wait for nVidia's 7950GX2 coming on June 6th!

Article: http://www.dailytech.com/article.aspx?newsid=2505

that thing is garbage its basically 2 cards sharing the same pcb and they claim its the fatest singlecard solution when its actually 2 cards

I guess your right but nVidia at least TRYING to get some competition back...

yea and it should start with the guys at marketing doin some rethinking about what there saying lol...i dont think we'll see any change in the single gpu platform outright speed crown until the next gen of cards arrive with direct x 10 support, but until then..ATI all the way!!

Sorry T4rd but this is so tech section...
Moved...
R

Tha game was kinda made for NVidia, and I have 7900, so easy pick

Damn straight brother Nvidia for games, Ati for a Media PC. Nvidia vs ATI is Like asking AMD or INTEL for gaming.Check out the pc mags for the comparisons. Its a no brainer NVIDIA and AMD.

Well I actually do have XP Media Center 2005 on here and do use the VIVO a lot to stream to my TV and hook my gaming consoles up to my PC with it also.  That's why I would like to know if anyone has and any expirience with the new AVIVO that ATI is boasting about with the new X1k series.

I tried out both cards before i stop on 7900, the resons behind my choice are as follows:
1) The size of 1900xtx is massive, becasue it's built on older technology, which makes it really hard to fit any other devices you might have in the case.
2)  The heat htat is generated by the 1900xtx is a lot worse than the 7900 because again older technology, more resistance and more heat generation with in the chip.
3) the power requirement of the 1900xtx is a lot higher than 7900 for the crossfire set up vs sli set up,
and again the reason behind the requirement is because 7900 is manufactured on a smaller technology than 1900xtx.

7900 fits in the case very nicely, it weights a lot less which makes it easier to fit other devices in, because my case is not a huge one so once i put in 1900xtx i lost 2 pci slots right away...

hope this helps....

cheers

Arent they both based upon a dual-slot design because of the cooler?  The only single slot 7900 series card is the 7900 GT.  By bigger, do you mean longer?  Cuz that's about the only way it can be bigger.

Can you tell me the specific temps you recorded on both cards?  Temps are an easy fix anyway cuz I have a Zalman GPU cooler on my X850 right now and it's compatable with the X1900 also.

ive used both and they perform almost on PAR but the 1900 is better at high reso with AA

Now, you see i'm in a bit of a pickle here.

I currently have a X1900XTX, however if the 7900's had worked for me i'd be using those instead, because they were my first choice.

If you get a 7900 that isn't flaky then stay with them, if you do then go with an X1900XTX. My reasoning behind this is that nvidia make excellent drivers that positively bitch slap ATI's. (Catalyst Control Center.. *shudder*)

Performance wise the X1900XTX does outperform the 7900GTX but like I said, drivers play a big part.

I'm voting X1900XTX because of my bad experience with the 7900's. However, i'm only voting for that because it's what I currently have.

I'd rather try to avoid the whole RMA process in the first place, heh.  So have you tried the AVIVO out on that card yet at all?

I still dont see what the problem is with ATIs drivers that you all are expiriencing..?  What makes nVidias' drivers so great??  I actually like the Catalyst Control Center, it's a nice GUI compared to nVidias', I think.  Why do people hate it so much?  I dont get it.

You happen to have a 1080P HDTV to try the AVIVO out on, EvilMonkeySlayer?  Hah.. or anyone else for that fact?  This is what I'll be using with my card here soon so it'd help me out a lot.

Also, it kinda pisses me off that Vista comes out late this year along with DX 10 and these cards dont support it (supposedly, I cant find proof).  If I pay $500 for a card, it's retarded if it doesn't last for at least a year or two before you should need to replace it to run the newest software/games.

Edit:  Oh, and you dont HAVE to d/l the Catalyst Control Center with the ATI drivers.  You can just d/l the drivers and control all those settings in the "settings" tab in the display tab when you click the "advanced" button.  That might help out a lil with your resources.
