Hey guys i just have one question about getting crossfire or SLI. Well i heard somewhere that it would be better only to get one of those two things if you run a game on a high resolution. And i thought having two video cards would be like doubling your video power? Now I want to buy a new computer this January and want Crossfire but I am not too sure because I am also going to be getting a new monitor(19' LCD TFT) this coming november or december with resol. of 1280x1024. I also hope to have this computer for a while and possibly later in many months get dx10(dx10 is not that interesting to me because it will probably be way way way out of my price range).

I know i have started to babble about everything else but i am mainly wondering about the one quesion...

Thanks for the help.

PS: I dont know why i started that poll, probly cause i just joined the site and it was was first post, lol.

Also i would want crossfire because its like getting 1 amazing card only buying a half at a time lol. I was thinking of the x850. But by january if the price is right ill go for gold and get an x1900

At 1280x1024, both are totally useless. Always get the best single card you can.

7900GT, X1800XT, X1900XT, X1900GT, 7900GTX, 7900GTO are all great cards, and will be perfect at that resolution.

You rarely come close to doubling your performance.

Unlikely. Dual cards are a luxury. It would be pointless for card makers and game makers to make dual card mainstream. Not everyone can get them, so it's not profitable for them.

Well we cant deny that dual gpu's perform better at any resolution vs single card. But yes, if you arent turning up all settings and running uber resolutions its not worth it. Here is some solutions I can give you if you want to buy this minute:

Single Card Solutions:

Nvidia- 7900gtx
ATI- 1900xtx or 1950xtx


Dual-Card Solutions:

ATI-
1900xt w/ cf edition (roughly $600-650)

Nvidia-
2x 7900 gtx SLI (more exspensive $700-850)


All in all you should just get the best single card right now if you want to buy right now and wait till Direct X 10 cards come out then buy either a single or dual card DX 10 solution

Hope this helped you out and someone back me up here :)

Ok thanks for the help i will go with one card now and it will sorta save me money. But now i just have to pray to god that the dam prices for the x1900's come down to 200!! If that happened i would........i dont know just be very happy. Wouldnt you expect them to drop like hell becuse theyre about to get owned by the DX10 cards.

If you want a x1900xt that baaaad right now for around 200 they just made a 256mb ram version which is just basically a x1900 w/o 512mb ram. DX 10 cards will own DX 9 cards so brace for impact! 8O But I would just go with a 1900xt w/ 512 and hang tight. The xt will play any game you want (bf2, oblivion, Source Games) You will be able to enjoy your games. But try your best to get 512 over 256. Remeber this card used to be 499.99 and now its 310!!

Wierd i got my x1900xtx 512 for $250 about a month ago. between $250 and $300 i dont exactly remember. But yeah single card at that resalution who cares if you go from 150 frames to 180 with a dual setup you dont need it Dispite the fact so far i seen only two games that actualy see a gain (or engines rather) whatever Oblivion and F.E.A.R. run on.

The prices will definitely drop in January - and that will most likely be due to the DX10 cards coming out.

For anyone else with a decent DX9 card (X1800 or 7800 series) I would wait on getting a second one if you're looking for a performance increase.

The DX10 cards will surely "own" the DX9 cards (AlexIrvine you're on the money there) and may even bring some issues of incompatibility as early as next summer with games (for high end effects).

Damn VistaBox...I mean X-ista!

Don't hope for huge price drops. Look at the 6800 cards (besides the crappy 6800XT), prices are high, and cards are rare, same will probably happen to current 7 series, and X1xx cards.

hmm....but wouldnt having crossfire be sorta like dx10? im sorry if that is a stupid question but i dont understand why dx10 is soooooo goooood to everyone. I know dx10 have a fillrate of like 80 Gpixels/sec. or something like that. So having crossfire or SLI would have double the fillrate of lets say an x1900 with however many a single card has x 2...now if that lil equation of having 2 cards and putting 2 in a computer isnt right then that is a lil F'ed up....someone explain it to me pleeeassse.


2 cards equals 2 times the power....? hmmm...wouldnt 2 x1900's stack up with an "o so amazing DX10"?

dx10 is a API how does it have a fill rate? it obviously will add alot of fetures and abilitys for card makers and driver makers but i dont understand how it will have a fill rate.

Always happens where next-gen's mid range card is better than current gen's top-end card. 7600GT > 6800Ultra etc.

DX10 cards will be much more powerful, and use new DX10 features, which current cards will not be able to render.

Sorry mate I can't get seem to get very excited about 9fps when running at nearly 100fps, I really don't think the human eye could perceive such difference I mean you forgot to put the Prey benchi in there with the whole 1fps difference
