2900 Pro X-fire or single 8800GTX for about the same price?

I currently have x1950GT and wanting to upgrade one of the above and probably sell the x1950GT.
Mobo is Asus P5K
q6600 OC'd to 3.2Ghz
580Watt HiperType-R

GTX is faster, but you pay a premium for it

Edit: Sorry I missed the crossfire part lol In theory two 2900Pro's in Crossfire would probably defeat a single GTX.

 

[spuddyt]

no idea, I've never even seen benchmarks (except some done in poland) for a single 2900 pro

Couldnt possably say as spuddyt says we havent seen enough about the PRO card to coment yet but general rule of thumb is that you get the best single card you can afford and the GTX is a better card than the PRO as the pro is basically going to be a underclocked XT at best,then i would have to say go for the GTX.

[spuddyt]

then again, that doesn't really apply in cases like the 8800 ultra where 2 cards would probably beat it for the same price

I don't know all that much about the technological advantage that the 2900Pro has over the 8800GTX, but I know that a single Pro is ALOT slower than the GTX. However you'll probably be better with the single 8800GTX over the lifetime of the cards.

interesting article with the good comparison benchmarks:

Seems like crossfire generally sucks compared to sli.

It varies in games. Xfire bests SLI in vista atm, for what its worth.

Personally id go for 2x 2900pro's. Their performance is only slightly under the 2900xt's and catalyst overdrive gets em a tad closer anyway. Theyd definatly best a 8800gtx.

or if i were u i would wait for decemberish and then get the new cards

 

[martyjs]

If your ready to buy now then do it! To many times I see people say wait until x month, If we all waited until something new comes out we will never buy.
I'd go for the single card as so one earlier mentioned there seems to be a lot of trouble with both SLI and Crossfire with the latest drivers especially under Vista

 

[shargrath]

the 2 2900pros would suck alot of power id wait till the 2950's apparently their 55nm : )

 

[Hatman]

Yes then in the new year the lovely new cards would be released.

Please give me your opinion which is faster...

Depends on the game and settings you prefer;

As you can see for the XTs it can way outperform a single card sometimes, and other times, like SLi it can have a negative impact on performance.

Check the results for the various games and you should get an idea of what to expect.

I personally don't like multi-card setups, but if it comes to the same price then you have to check the options for your specific games/apps.

LOL @ U !! You have to pull out a review from before the HD2900's launch? :lol:

Lame!

Try posting a review that was done with retail hardware and recent drivers. Heck when that review was written nV still couldn't get SLi to work with Vista at all, and it seems that despite the M$ patch and updated drivers, nV was still having trouble all the way up to the last driver release ;

So until they finally fixed things on the 163.69 drivers SLi apparently sucked alot more, right now they're pretty much the same.
