9800 GTX questions

Well the 9800GTX SLI is out before I get my funding together for a new DTR class laptop. Not hard to choose the 9262 {only real choice and I am partial to Alienware}. So I turn to those with more knowledge than I to help me choose between the 9800GT SLI and the 9800GTX SLI. The main use of my computers is for gaming. I will use it for surfing, research and watching DVDs but over 90% will be gaming.

I've read that only 512mb of the Video memory is able to be used. Is this true? If true, then what is the reason for a full GB on the GTX?

I've heard that the GTX SLI will be a performance increase of 10-15%. Does this equate to a 10-15% increase in fps? Are there any future proof reasons to go with the GTX?

Any other ideas on the 9800GT vs 9800GTX that I missed?

Thank You

 

1)no,that only goes to weak video cars
2)GTX is 10-15% faster then GT,but in SLI it will a little more faster then 15%
3)yes-paying 500$ more for a little gain is pointless IMO

 

Unless you have the extra $$$ to drop on the cards, it is not worth doing the GTX. IMO, go with the GT's in SLi. But if you want 224 shaders and 2GB or vRAM, you won't be dissapointed in the performance you get.

 

This is my older 9262 running COD4. AS u can see, there is still plenty of power left

User-run FPS benchmarks (such as 3DMark06 graphics scores or in-game benchmarks like the Crysis one) vary all over the place depending on CPU, OS, user settings, video driver...etc., and I haven't seen enough "apples-to-apples" comparisons of the 9800M GTX and the 9800M GT, to establish a quantitative difference. The GTX does seem to be a little faster, but it's clear the difference is quite small. Your guess of 10-15% may not be too far off the mark.

Other than its speed advantage, I don't see anything in the GTX that makes it any more "future proof" than the GT. Considering the difficulty/impossibility of upgrading notebook computers, about the only future proofing we can usually do is to buy the fastest machine we can afford at the time we need to buy. If I could "afford" the GTX, I'd buy it, but if I thought I couldn't, I'd buy the GT and not lose a wink of sleep over it.

 

wow 3 different topics on the 9800m gtx.

@topicstarter, I'll have my dual 9800m gtx after tomorow (I hope..). I have been searching for ages for anything on them..but nothing. So if you wish me to test anything, let me know.

 

justanotherguy, what would you like to know about the cards? I can get you any technical information on them.

 

Yep I dont know anybody else who ordered GTX in SLI. My order will ship in at least 2 week time Post 3dmark06 scores, crysis and other game benchmarks when u receive it.

 

If you have technical information/reviews/benchmarks on the sli setup,please post everything you got I couldnt find anything!

Ok I will!

 

Here is all the technical information for the 9800M GTX in general. Some things will be different from this to yours, such as the BIOS version and perhaps the ID, but everything else is essentially the same.
