Hey can someone tell me which is better
*2 4870 in crossfire
*2 4890 in Crossfire

And can you get more performance from a graphic card when u crossfire them than using a single card?

2 HD 4890s perform better.
Well CrossFire is almost always better than single card unless you play mostly CPU limited games like FSX or you play at a low resolution like 1280x1024 or lower

Because of the extreme low prices of the 4870s and 4870x2s right now (if you do a little bargain shopping you can get them for about $125 for a single card and $200 - $225 for the x2) the 4870s are probably a better bang for your buck...so unless you are running higher than 19x12 resolution you probably have little to gain from the 4890s.

I read the "best grapgic cards for the money. November 2009" article on tomshardware.
And i found out that 2 4870 1GB in crossfire is bettr than some ATI 5000 series GPUs.

And i got to know that 5000 series has many new feature including direct x 11 etc....

So should i buy the 2 4870 1GB in crossfire or an ATI 5000 series GPU?

My budget is less than $150

The HD5750/70 will most likely run on your psu. The HD4870 Maybe if it is a quality unit. I would be looking for HD4870/90 1GB (little more than $150) or HD5770 (little less perf) for that system.

But they have to be less than $150

And i know that the prices of an ATI 5750 or 5770 is below $150 on ebay. But on Tomshardware it said that some 5000 series GPUs such as 5770 do not deliver a gud performance like a 4870 or 2 4870 crossfired.


I know that 500 series has new technology but some say they dont have gud performance????????????

SO tell me whether i shud go with a 4800 series card or a 5000 series ATI card?

If you have windows vista or seven buy a 5770 card because then you can use the DX11 feature. If on windows xp buy 4870/90. Good luck finding them under $150

FSX is mostly CPU limited so you need a good CPU first,and BF2 can run on single HD 4870/4890 with max settings,if you mostly play these 2 then single
HD 4870/4890 would enough,but if you play other games tell us and plus what resolution do you play at ?

I decided to buy an ATI 5770.

I live in Sri Lanka. These cards are not available here yet. So im planning to buy it from a website such as e-bay.
From which site can i get the lowest price for the above card and shipping to Sri lanka for the lowest price?

when i checked several sites i found that there are a large number of brands.
Does this brand really matter?
And can someone recommend a good brand.

And what is the minimum PSU requirement for that card? I currently have a 450W PSU. Will that be enough?

Are there anything else that i should consider before buying this graphic card?

And what is this 6 pin PCI express power connector?
i checked my PSU but they dont have those connectors. Instead it has some 4 pin connectors which i use to connect my DVD writer. So what should i do?

Your 450 should be enough if it reasonable quality. Difference in brand names is mostly warranty you should look for a min of 2 year warranty. Sapphire is a good brand. Minimum psu for the card is 450watts with one 6 pin pcie 75watt connector. Most etailers in the US don't ship overseas.

Card usually comes with a adapter that takes 2 of your 4 pin molex and makes one 6 pin. see pic http://www.newegg.com/Product/ImageGallery.aspx?CurImag...

What is this Memory bus?

When i checked the graphic cards on tomshardware i found that the memory bus of the ATI 4870 1GB is 256bit. But the new ATI 5770 has a memory bus of only 128 bit. Therefore which one is better?

Two 4890s will be way more powerfull.
A 5770 is like a 4870 in terms of performance for comparison.

The 5770 has DX 11.

If you look at the top of the page there is a STICKY that says "5770" reviews. A little reading can't hurt.

Some one else can hopefully say what it is exatically, but what i do know is that you dont need to worry about which is better. Just look for reviews of FPS performance of the cards you want to get a good feel on how the card performs and make your decision off that.

Look at it as a pipeline. And look at games textures as the water.

Bigger resolutions and better games (Crysis etc) need to move more of these around than lower resolutions and other games not as much.
Take a look at this review and you should see on the graphs where the 5770's 128 bit bus starts hurting it performance wise.

The HD4870 performs slightly better but the HD5770 has a large advantage in power efficiency and is DX11. Lately it's cheaper as well.

in RAW performance, the two 4890's in crossfire beat 5770. If your looking for something more future feature packed, with less heat, less power etc then its clearly the 5770.

There is no comparison between both options, maybe dual 4890's vs. dual 5770's but it's kinda like comparing dual corvette's vs. a single mustang....

Even one HD4890 is more powerful than an HD5770. If you are considering crossfiring HD4890s make sure your PSU can handle it and your case has good airflow as those cards are quite power hungry and run hot.

Damn.
Just get the HD5770 already. If it's too expensive get an HD4770. Either will be great for your resolution and work fine with your PSU.

The 4650 is going to play those games like crap. Definitely time to upgrade.

Any of the 4870, 4890 or 5770 will do pretty well. But I'd get the 5770 because it has DirectX 11.

Your card is crap for today's standards. Get at least a HD 4890 or a GTX 275.

A 4650 will play those games at lower settings, but that is about all.

Out of your list the performance goes int his order 5750<5770<4870<4890. However, The 48xx cards will draw more power than the 57xx and are only DX10.1. If you want to run DX11 games in the future with DX11 you will need one of the 57xx cards. You also need Vista SP2 with the video update, or Windows 7 for DX11.

It depends on what you are looking for. A 4890 will have the most raw power, but uses more power and is not DX11.

What PSU do you have? You will also want to ensure you get a card that your power supply will be able to handle.
