Those heatpipes become sizzling hot after a quick game. Perhaps get an Antec V-Cool? So far FEAR ran fine. But then again, my gaming sessions last less than an hour.
I wasn't wondering the company so I could say if they were crappy or not. I was wondering whether or not the problem just extends to EVGA cards or other makes of the 7900 series.
I think its kind of weird how some people are having to upgrade power supplies for this card. Maybe its just from various posts I've seen but a lot of people, some who used to have 7800GT's, are upgrading their power supplies just for the 7900GTX's. Don't they use less power than a 7800?

I don't have Oblivion. I noticed the GTXs get very hot when stressed. Overheating? Maybe this weekend I'll play BF2 for more than an hour. Kinda funny, though the MSI came in stock speeds, they include a OC utility.

I'm just trying to give them a fair shake, that's all. I've got an RMA form now though, so YES, the card is an eVGA. As far as the PSU goes, I read somewhere that the 7900 is more CURRENT hungry than the 7800... However, given that they both feed off the 12V line, and the 7900 has less wattage, my [limited] knowledge of physics leads me to believe that the "more amps/current" theory is just BS.
By the way, updated my BIOS to 1205 last night - no change in artifacting. HOWEVER, after resetting the BIOS to "defaults" and rebooting (before fine-tuning ram timings etc), the screen did not artifact for MUCH longer than before...making me wonder if there isn't some BIOS tuning which is playing a hand here. I'll try and experiment with it a bit tonight, and get back to forum with result.

Well chances are its probably best to RMA it (especially with EVGA) and then try again. I wouldn't experiment too much since it probably wont be worth it. The card is defective. Return it for another.
Nope... EGS version - stock nVidia specification speeds.
Have been doing a bit of tuning with the new BIOS. Still frequent artifact, with occasional lock-ups in BIOS. Since installing the new hardware (into STABLE machine with BIOS 1009), I'm beginning to think that a BIOS flash just added another variable to the problem. Hindsight is 20/20 though.

My last post to this topic...
Happy to say I've FIXED my problem. It was NOT the eVGA 7900GTX. Unfortunately, I'm not sure that it would be very apparent to most users, as the artifacting could be described exactly like the problem wihich appears to be occuring with the 7900GT cards.
Basically, I noticed that the could would run under linux...flawlessly in fact, and without artifact, in spite of how hard I pushed it, even with 3D apps. But whenever booted to windows 2000, I'd have artifact within a few minutes, and usually a system hang shortly thereafter. Anyway, a working card under linux REALLY made me suspect that it wasn't a hardware issue.
Ultimately, I think upgrading the A8N32SLI BIOS to 1205 (which is the one where they officially state 7900 supported) was what did it. Initially, it didn't look like it fixed the problem, but I think that was mainly as a result of minor instability introduced to the system by continuing to overclock, even after adding a power-hungry (stock speed) 7900GTX. Once the BIOS was updated, and I backed off on the system overclock, I was (and still AM) in Oblivion heaven. Since then, I've tweaked my voltages a bit, and am back to the original system overclock (see sig below), and the 7900GTX is working great under windows... of course, I've somehow hosed my Xorg setup, and can't get linux running right (console works fine), but that's for me to sort out - 99% sure its just a config file somewhere.
Anyway, short story = eVGA 7900GTX works fine, and company had even agreed to RMA card in spite of what's described above. I tip my hat to eVGA... I would recommend, AND will buy again.
Thanks for everyone's input - sorry if I highjacked the thread.

IMO if the card is running 'hot' then it's probably got a problem. In my experience (of my single card ) it runs very cool. It runs about 20degrees over my room temperature at idle, and about 40-45 degrees over it under continued load (>hour)
I thought I'd quote my temps 'over room temperature' so you could apply them to your situation a bit better. More people should do that :roll:

Yes, My Son has 1 and it has quite a few problems. Yet my other Son has the XFX 7900GT with no problems whatsoever?With the stock bios of the 7900GTX (650mhz & 1600mhz) it actually was worse as I found after I flashed the bios with XFX (690mhz & 1750mhz) the card performed more reliably which surprised me and completed the FEAR test with very high test results.This is not a heat issue, I've probed the card at various points with temps never getting over 59 under full load. It's almost similar to a memory leak related problem, seems to be very random, and the screen will flicker on and off sometimes when he exits a game or when we run ATI tool just to load the card and scan for artifacts which do occur and check the temps while ATi tool is running. It's weird and sometimes when it feels like it, the system hard locks. These problems I have seen occuring through other peoples forum threads relating to the 7900GTX. I will let you know when I get intouch with the wholesaler whom I purchased it from here in OZ to find out what they recommend.
Steveo,
That is weird that your card runs better when overclocked! There are two ICs on the backside of the card at the end opposite end of the DVI port that gets very hot. I stuck two heatsinks and have a 80mm fan blow air over it. I don't know if it helps for not, but I guess it is insurance. My card is still running fine @ 650/1600.
