Ive been trying to choose from one of these cards for a few days, and i just cant seem to be able to do it, because their performance is so close.
I have an FX5200 now.

The X1900XTX seems like this "magic" card - It has too many Shaders WICH is overkill so it cant add to performance, and it has a too little ammount texture fill wich is the most important thing in any game, so that cant help it. According to it's specs its supposed to be much worse then the 7900GTX, but its not, so thats why i call it "magic", because it's specs arent as good as it's performance. Dont get me wrong, i think the XTX is an amazing card, but it has too much of what it dosent need and not enough of what it does need (wich the GTX has 2x of).

The 7900GTX, well since i have an Nvidia card right now, i feel closer to Nvidia and i think i would feel safer and better knowing that i have an Nvidia card, but i wouldnt WANT that to influence my decision, because i want to get the BEST card, not the one that i like the most because of sentiment.

I heard that each card has different features, like AVIVO or PureVideo. Anyone know anything abt that and can help me decide, id love some input.
Thnxah yes, the age OLD question of nvidia or ATI... there really isn't a right or wrong answer, both cards are great and an improvement to your system. people can argue round and round about which is better, but really it's a matter of preferance. i myself prefer nvidia, i have the xfx 7900 gtx and couldn't be happier. its a great card very fast. but so is ATI's i'm sure. you might want to wait though if possible, because supposedly they have the next lvl of graphics cards coming out soon? maybe? directx 10 cards and such i'm not sure, its been awhile since i've looked.I'd agree and wait, if not only for the price reduction that the NEW cards are bound to cause. All the new stuff that comes out DX10 compliant will cause the DX9 cards, the current high end, to drop off pretty well, im sure.

As far as Nvidia vs. ATI, well, there are lots of things that could cause changes coming up. ATI was just bought by AMD, and so that may be a boost in terms of compatibility, but it's too soon to tell. I personally have an nvidia 7800GTX, and i think its great.

if you feel more comfortable with an Nvidia card, then thats what I would suggest.Does Purevideo really cost money

No, the DX10 cards still have a way to go, and im not going to wait, they want ppl to buy their cards, they better release them before the summer.Quote
