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

What are the specs on that PSU?

Ignore the title, check out the benchmarks:

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.

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

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.

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

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

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%.....

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.....

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

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.....

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.

If you're not thinking of upgrading, and have spent some money on an i7 processor, you can not argue about that. That 2 ATI 4890s are a better choice to be honest than having one gtx 295 or 2 gtx 275s. The performance of the 4890 x2 is amazing anyway. Already overkill since it is better than the single best GPU.
