I've had the opposite issue with stability. I have had zero.. none, no problems with my V5. I find the GeForce guys having to rollback DX8 or look for older or newer drivers, etc. etc. etc. I just install the latest V5 drivers and keep on trucking.
Also, the GeForce cards will NEVER have the same quality of FSAA as the V5 can produce. The method they use is markedly inferior. Even their "2x2" level (what they call 4x) of FSAA is markedly inferior to the V5 version. Basically, the way nVidia does FSAA they only really do the FSAA on the vertical lines, where the horizontal ones still look like crap. There are a LOT of horizontal lines in a WWII flight sim. The winglines of planes being the most obvious. Take a look at this picture:
http://www.dogfighter.com/images/reviews/aceshigh/010108/ah6.jpg Look at the vertical surface edge of the rudder, and then at the horizontal stabilizer edges. Look at the horizontal versus the vertical edges of the bay doors. Jagged crawly garbage. I could tell in a glance at the first picture on the page that those shots were from a GeForce using FSAA. On a V5, the horizontal lines are as smoothed as the vertical ones. It is even more noticeable in a game like AH where you spend a lot of time (hopefully) looking at the horizontal surfaces (wings and tail plane) of enemy planes. Those horizontal anomalies and crawlies are the issue for me, and they don't get smoothed properly with the GeForce under their crappy FSAA scheme.
I've put the two of them side by side and I'll take the V5 every time. If nVidia ever comes up with a decent FSAA implementation, I'd get a GeForce 2, but their current implemntation is crap IMHO. I have an Athlon 700 and a V5 that I play 1024x768 32 bit and I get 30-45 fps pretty steady. That's plenty for me. I can get higher or lower in the odd situation like flying through smoke, but I almost never see any kind of a frame drop that hurts my gameplay.
I hope nVidia takes 3DFX's FSAA technology and builds it into their next line of cards. Give me a card that will do 1024x768 32 bit color with a REAL 4x FSAA implementation at 60 fps and I will pay big dollars for it. Until then I feel the V5 is the best for me personally.
