Video Card Comparison Question?

Asus Radeon HD 5770 1GB or the Sapphire Radeon HD 4870 Vapor-X 2GB or the Asus Radeon HD 4890 1GB? which one is the best and why? here are some of the games i play gta 4 nfs most wanted nfs shift crysis and games like these. but out of these 3 which one would be the best for most games. and also can you tell me which one is the best and then the second best and then the last one. thank you|||I would go with the Vapor-X 2GB because of bigger memory. But, you gotta look at speeds too. Although the speeds matter, the memory is more important because of the cards ability to store more video processing commands which means lesser lag.



At the end of the day, you gotta look at both, the memory and the speed of the memory. They have to be proportional.



And also, DX11 does not mean better. The card needs more power to process DX11 then DX10 or 9. So don't really look for DX11 because not a lot of games support it.



In the future, consider upgrading because now DX11 is at it's baby stages and still is being worked on.|||In order of best to worst of an excellent trio of cards...

4890

4870

5770

EDIT: Ranking based on Benchies performed by Tom's Hardware on real-world games and systems as well as 3D Mark.



While the 4870 has double the memory, this does not mean that there is a significant boost in performance, nor does it mean more power (that is strictly the perview of the GPU). Once the card's memory exceeds 512mb, the amount has a smaller impact on performance than most think, because of the speed of data transfer across the PCI-e bridge. The only real advantage the Vapour-X card has is the more efficient cooler, which means that enthusiasts have an easier time overclocking it without needing to worry about frying the GPU.



As for power draw, the HD 5xxx cards draw about the same to slightly less power than their 4xxx series equivalents while at an idle, because of the die shrink. Mind you, the higher clock and memory speeds and additional processing power tend to eat-up most of the savings.



That being said, based on "Future Proofing," the HD 5770 card is the better card, and at less than $200 or so, an excellent deal. (Put two in Crossfire, and they drive both of the other cards into the ground!)



Good Luck!|||As always, when Gaming the most expensive graphics card is the "Best" (whatever that means)!



Why? Because it makes the manufacturers the most profit!



Summary: (1) Graphics Card, (2) CPU, (3) RAM, it isn't just about Graphics, it's all 3, working together!!!



TIP: The higher the ATI, or nVidia, Series AND Model number, the better the performance, regardless of Manufacturer. Read ALL the Video Card Charts at Tom's Hardware for more info:|||the sapphire radeon is the best. The increased graphic card ram will improve performance. This is a good grahic card that produces detailed graphics. then is the 5770 and last is the 4890 because of the low amount of ram in it.|||get the 5770 because its cooler, has dx11 but it is on par with a 4870 but if you overclock it it will go way past 4890 speeds.|||5770 is a good card,

But the hd4870x2 is better
