Just vote the Video Card company that seems more dominent to you.

I dunno about dominent but IMO ATi for sure.  They make better drivers and solid cards. Also better image quality.

yeah but the the ati have nothing on 8 series. Image quality took ati's. I never thought the day would come but it did I use to love ati!
 

Nvidia for one reason: Linux.

They do, just not in the super-high-end segment. with the new drivers there mid-high range card does infact come close with the GTX. I really wish their flagship card (HD2900XTX) came out. It looked pretty impressive.

nvidia because of personal familiarity dealing with drivers, and support for linux thus far as was mentioned... but from an overall performance perspective, it could go either way depending on price/performance and availability.

nvidia for driver consistency and overall ease of use

ATi. They know how to make drivers and dont just throw **** out there to be the "best". As much as  I used to love nvidia, they are just getting real **** lately.

ATI, they release drivers regularly. They just opened up their specs, for open source drivers, nVidia has not. I always have problems with nvidias drivers and rarely with ATI.

Which brand do I prefer?  AMD for the most part.  It actually matters on how much I have to spend.  I prefer to buy the fastest part for my price point, regardless of who made it.  If I run an AMD + Nvidia this month, and an Intel + AMD the next, as long as it was the fastest that my money could buy, then I'm happy.  
 
For example, if I can get a 7900GS for my $110, then I'll buy that because the cheapest x1950pro I could find was $145.  If I have $175, then i'm buying the x1950pro because I can't afford the 8800GTS.  If I have tons of money and don't care how much things cost, then you'll find an 8800GTX in my system.  (I didn't say Ultra because I'm rich, not dumb...)
 
For me its all about how much I can get for my limited dough.  I don't care who made it as long as its the fastest that I can get, at the time I'm buying, without going over budget.

Ati but its performance and quality is what i decide my purchase on

ATi, i think this hd2900 has a lot left in it we have not yet seen, and if you think that Ati lost the image quality trophy... Lost coast...

But i am a fanboi....

a poor one.

I never count Ati out but at the moment its left in the dust. I was kinda suprised that the 2900s fell so far behind the Atis, but thats how the wind blows

DITTO!!!!

Nvidia
 
I had a great time with my 6600GT, still works like a charm...

My last ATI card was a S3 Rage 8mb.  Since then Ive had all nvidia cards.  However I would have no problem using a ATI card if it had the right performance for the price.

For gaming I am using nVidia, but for my HTPC it's ATI. It's hard to beat the All In Wonder series just don't use the ATI software.

I like nvidia's (whatever manager) to ati's control center, green > red..

I personally preferr nvidia because of prior bad experience with ati cards. (3 bad cards in a row, how unlucky can one be?)
So, even if nvidia doesnt deliver the absolute highest performance I get a good working card and that makes me happy
