I'm building a high-end system, and have the graphics card narrowed down to either 2X GTX 275 or 2X Radeon 4890. They seem to be similar price and similar performance, so which one should i go with? Also, is an overclocked card worth it? My mobo is a Asus P6T Deluxe, with an i7-950 cpu.
Thnx!

"Two Radeon HD 4890 cards should, on average, perform on par or better than a single GeForce GTX 295, and the Radeons cost less. If you have a CrossFire motherboard and want some serious high-resolution performance, this is the way to go."

"t's funny that we're recommending two GeForce GTX 275 cards in SLI over a single GeForce GTX 295, when you consider that each GeForce GTX 275 is essentially half of a GeForce GTX 295. Saving the $210 compared to the GeForce GTX 295 doesn't result in a performance penalty. If anything a pair of GeForce GTX 275s will display a slight performance edge due to their faster clock speeds."

ASUS P6T supports either board. Seems like the performance is about the same so price might be the deciding factor. Shop around, look for deals.

You need to see which performs better in your games. Of course, chances are both solutions will rock anyway. HD 4890's are cheaper. In the USA you can find them for $165 AR. (zipzoomfly right now)

Regardless of which one i get, what kind of power draw will be looking at if i get 2 of either one? Right now i'm looking at about an 850 watt corsair power supply.
 
To me the DDR5 is not what makes the real horsepower, its the overclocking and shaders/SPU's.. in real-world benches someone can come up with dual 4890's overclocked and give the 275's a spankin, while someone else can come with dual 275's overclocked and spank the 4890's..... It all depends, hardware, CPU overclock and a variety of other tweaks....
 
DDR5 does not mean it has better overclocking ability IMO...Lets compare these :

295 : 1792MB GDDR3 <---- not even 2 gigs of DDR3

4870x2 : 2GB DDR5 <------2 gigs of DDR5

Winner = 295 by a small margin

So in all the DDR5 theory is out of the question....

Well do it like this

If you are going for a high OC
4890's they do oc better then the 275 as they are really just 4870's on a new board made for higher oc's

At stock flip a coin, find a fav game, fav brand?
 
buddy did i say GDDR5 overclocks better? i said 4890 overclocks better "better overclock capabilities" , read the damn reviews if u aint know what u talkin bout

295 wins..we know that AFTER 4870x2 was released months..

I read the rewiews son, i know what i am taking about I never said that the 275's were better I said it all depends, its neck to neck in some instances and in other its by a larger margin, read above...

So your comment regarding "what can a 275 accomplish that a 4890 cant" does not make sense...

Im just giving you my opinion, if you are an ATI fanboy then good for you as i love both and could care less is the 275's are faster/slower.

and BTW the "295 wins..we know that AFTER 4870x2 was released months.." has nothing to do with it, both are dual GPU cards battling for the top spot...
 
Now i will tell you this, if i were to choose at the moment, yes i would go with the dual 4890's just cause it would be easier to achieve a higher clock speed (less messing around with voltages and overclock) as opposed to the 275's. But this is just the same cycle that we see on a monthly basis, the real test will be the 5000 series vs. the 300 series......
 
Hehe, no worries... same thing happens to me every now n then......so you are not alone.... There is nothing wrong with having an opinion.....I just want you to know this, normally when i post something like this its due to the fact that if i do not see a night n day difference comparing 2 similar cards from different manufacturers, IMO its a matter of taste, and not if the other card clocks better... In all the winner here would be the 4890 due to the fact that for the price you simply cannot get a better card....ATM...

As far as release dates for the new cards, I am not sure when they will finally give us a definitive answer, I am thinking the beggining of next year, but who knows... They can come early like they can be pushed back, we will have to wait n see......

at high resloutions, 4890s
otherwise doesnt really matter

consider wating for dx11 if u can (i cant so im upgrading now lol)

corsair 850tx is a great psu

either way ul get great performance, better than a 295

enjoy

Think i'll go with 1 gtx 275, with another one as my first upgrade. (As money comes in). I don't plann to do any ultra-modern gaming for about a month or two after i build it(Just playing bioshock), so i think i can upgrade later no problem. Thanks for all the help! :D
 


You got a heck of a deal there son....... [:jaydeejohn:5]

would a 750w corsair have enough for dual 4890's, or would a 850w corsair be needed...with his rig, and maybe a slight OC on his processor?

Here are some links you may find interesting

Crossfire 4890 on avg beat a GTX 295 in all games at 1920x1080 resil

http://www.techpowerup.com/reviews/ATI/HD_4890_CrossFire/3.html

And this article shows how a radeon 4890 at its max potential at 1.0Ghz (overclocked from 850Mhz which you can do easily) came only 1-5% behind in fps to Nvidia's GTX 285 overclocked to its max potential.
