Both of them are good cards... Hmm, I dont know I might go with the HD4850, has a 1GB VRAM and hot air is being pushed out of the case. Although the Dark Knight heatsinks, like the one on the 9800GTX, are good too, they require better case air flow. Plus you can always do crossfire in future with another 4850 if you motherboard supports it....
I've been looking at some review, and the 9800 seems to do slightly better. Does anyone have any reasons or links to why this specific 4850 is the better choice. I was also wondering if the extra 512MB will really be used, are there any games that use the extra memory?
Seeing as thes cards are so close, you can rest assured that you won't make the wrong decision. My choice in this matter would depend on the native chipset of the MOBO (if it supports SLI go with NVIDIA if crossfire go AMD... if neither flip a coin)
If you play at 24inche native resolutions you will want the larger frame buffer, it ill make a substantial difference. If not, you are correct to assume the memory makes little difference.. Of course, if you are not concerned about the memory being an issue why not get a substantially cheeper 4850 512mb (you would however lose the very impressive matrix heat sink)? or even a 4870 512 would be about the same price. The sapphire 4870 512 is only ten dollars mroe than the matrix 4850 1gig. (at canadacomputers anyway)
Wait a second, even at canada computers teh matrix is 30 dollars LESS than the 9800. Did you make a mistake or is that "pretty much teh same price"?
You can get a 4870 for less than the 9800 from canada computers.
Goven that you would be kinda silly to take a 9800 for more than a 4870. Even if the 4870 is sapphire and stock cooling. The DK heatsink isnt worth that much IMO.
First off, the 4870 is a far better card than the 9800GTX+ if that is were we are..
Second. I do not personally think that the DK rendition is worth the extra 50 dollars. But if you are confident the mail in rebte will work out fine (I'm usually hesitant on counting on them 100%), then the DK is probably worth the extra 20.
I thinking the 9800 is gonna be the best option in this case. The speeds are just so much faster and I dont think there are any games out there that really take advantage of 1GB of memory vs 512MB.
I'm not too sure yet though, so if I'm wrong and the extra 512MB really does make a difference please let me know.
Thanks a lot for all the replies thus far.
The "speeds" have nothing to do with it, they are a different architecture. The 4850 and the 9800 GTX+ are basically the EXACT SAME THING, they vary a bit depending on the game but both get about the same overall performance. The 4850 can pull off 2x/4x AA without a performance dip, the 9800 GTX+ can not.
Is the DK one worth the extra price? I see that it has a much higher clockspeed on the memory and chipset. Is it big enough to justify the extra ~$20?
Again you can not compare the clockspeeds between the cards, they are different architectures. Remember you will be paying $270 for the 9800 GTX+ and $230 for the 4850 up front. You will get an extra $50 in the mail after about 6-12 months, those prices are not comparable.
