What is better? 1 GTX 295 or 2 ATI 4890?

[Nashsafc]

I want to know which is a faster configuration, having one gtx 295 or 2 ATI 4890s? I am configuring a computer on pcspecialist.co.uk. Also i have configured the computer with a 800 watt real power PSU. I don't want to increase the power of the PSU because it will go over my budget. I want to know what's the best configuration with a 800 watt real power psu and SLI or CFX can be used if this can improve the performance because my motherboard supports SLI and CFX. I am thinking that one gtx 295 is the same as two gtx 260s put together? One ATI 4890 seems to be better than one GTX 260, but by putting two ATI 4890s together, will this still be better than one gtx 295 graphics card?

What are the specs on that PSU?

 

[Nashsafc]

It just says in pcsepcialist.co.uk 800watt Quad Rail PSU SLI CFX certified. They also say that their PSUs are based on their true power trather how much the PSU says it is. Put it this way, it is very expensive, can we ignore the PSU now please.

Ignore the title, check out the benchmarks:

Looks like coozie answered your question. Go with the dual 4890's if you need that insane performance....Dont know about the 800w PSU though, if its the Coolermaster realpower , I would suggest you upgrade that first....

To be honest guys i'd be stupid not to go for the 4890 CF configuration, it costs 60 pounds less, is slightly better than one gtx 295. I shouldn't go for a gtx 260 or 275 because they would actually cost more. Would also require a bigger PSU which would also add to the price and wouldn't really have much more of an improvement in performance or would they? 2 gtx 260s are almost equivilant to one gtx 295, they consume more power than a ATI 4890, and cost more because i would have to configure a new PSU. This is where ATI wins over NVIDIA it seems? The 4890 is better than the gtx 260 as well and it costs less.

I agree, another option is wait till the new cards come out.... the 4890x2 looks like it will be the card to beat.....

GTX 285 BY FAR. ati 4890 heats to 150 c while playing crysis imagine 2 it is a valcano

150c ??? I think you meant 150F, @ 150c the card would be TOAST....

 

[edeawillrule]

no 150 celcius ati radeon has massive heat problems

Blasphemy!

If you don't know how to manually change the fan speed or have a defective card that could happen, sure. But it isn't as big of a problem as you're making it seem.

 

[Dekasav]

I give you a 100% chance it's not -actually- at 150c. Either your temp reader is wrong, or you're just inflating numbers.

 

[JAYDEEJOHN]

The differences are transistor density. The 4xxx series are packing 30-40% more tansistors in the same amount of space as the G200 series, but also use closr e to the same power, so, in effect, it has less area to actual release its heat. Theyre fine running hotter, but, ultimately they dont put off any more heat than do the G200s, while they do per sq mm, theyre also smaller

 

[invisik]

Jimdog do you have any proof they get that hot?

Have you ever owned ati cards?

 

[OvrClkr]

Like I said, 150c and the card would be toast.......maybe he had a bad ATI dream.....

 

[rangers]

the 4890 runs cooler than the 4870, my 4890 does not go over 69c running crysis

 

[OvrClkr]

69c is tolerable but it's kinda on the hot side.... you have your fan speed set manually?

My 275 never reaches 52c with fan speed on 50% and my dual 250's have never seen 55c with fan speed at 40%.....

 

[rangers]

no fan is on auto

 

[OvrClkr]

Next time you play a game, try manually setting the fan speed and keep the temps below 60c.....The cooler you keep the card, the longer it will last you.....

Tom's has used the 850W Coolermaster Real Power PSU for years and it's still working. There is nothing wrong with the line of PSUs, although I would get a Corsair over that brand.

He does not have the 850 Real Power, it is the regular 800 (rev 2) two different PSU's......

An 800W Coolermaster is fine for the 4890s.

My 275 never reaches 52c with fan speed on 50% and my dual 250's have never seen 55c with fan speed at 40%.....

That’s wrong. I have see people with the GTX 275 (fan set 60-70%) with temps around 80C(load). Excepted if you live in a room with 5C(room temp).

Next time you play a game, try manually setting the fan speed and keep the temps below 60c.....The cooler you keep the card, the longer it will last you.....

That is not true. For a single card normal temp is 70-80C and for dual card is 80-90C and that temps is totally safe!!!



From 07/02/2009 you have post 508 posts that makes you the bigger spammer I have ever see in my life.

 

[OvrClkr]

First of all where did you come from? lol.... Second, there are many factors as to why my card temps are this low....I have been doing this since the early 90's back when AGP was the shiznit..... Third.... If you are jealous cause I have a brain and use it to my advantage then you should do the same.....And last but not least your name does not suit you, you should change it to Unsuccessfull_troll...lol

My posts do not consist of spam, go through them, you might learn a thing or two.....

How would you know if that 800w PSU can handle both of those (POWER HOGS)??? Did you do your research?

My 275 never reaches 52c with fan speed on 50% and my dual 250's have never seen 55c with fan speed at 40% <---- this is a fact son......of course taking in consideration that my ambient temp is at 25-27c on a daily basis....

And FYI 70-80c is not normal, if this is the info you give others then go back to school....

The other day you posted on a thread :

All men who respect themselves should buy a 500.00$ video card on a yearly basis, if you don't do this then you dont respect yourself<----Talk about SPAM

 

[Nashsafc]

i don't know what PSU manufacturer my PSU is made by. The computer i am configurating is from pcspecialist.co.uk, they do not say what company the PSU is from. But they say that their PSU's are listed by their true power, and that they are good quality. The PSU i have is an 800 real power PSU, and it is also Crossfire X and SLI certified. So surely there has to be no problem with my PSU. I think with the computer on full load it will consume 773 watts of power. To be honest i think the gtx 260 and 275 are pretty poor round this point. The gtx 260 isn't as good as the 4890, consumes more power and costs about as much as the ATI 4890 on pcspecialist, plus you need to upgrade the power supply meaning that it will cost more than the 4890. The gtx 275 is a bit better than the 4890 but consumes more power and it costs a lot more actually when you buy two of them, this is without upgrading the power supply either. Upgrading the power supply with buying 2 gtx 275s would cost even more, and the extra performance is not at all worth the extra money. I think ATI have done reasonably well with this card; you can stick 2 together which would be cheaper and slightly better than one gtx 295 card.

I have seen people with much worst PSU running two 4890s with no problems.

Nonsense

Nonsense again…


Now, go away spammer and never come back!!!
