Hi, i wanted to know, i currently have a 4830 and i want to get another card, since i cant find any other 4830's (since they rather old now) i was going to get a 4850 and crossfire it. but what i wanted to know. should i get the 4850 and crossfire it or should i get a 5770 and have it on its own?
I don't have allot of money which is why i was planing to get the 4850, but in terms of overall performance, it is worth getting the 5770 over the 4850 crossfire? since i see the 5770 only has a 128-bit rate.

i would do with the 5770.prices will come down alittle later,then maybe you could grab another.the memory on that card makes up for the 128 interface from what im told.my friend runs the asus 5770 and he is more than plzed.

I believe Dual 4830/4850's will be faster. But the 5770 is a solid card. DX11 games will see performance advantages not just graphic enhancements, less power, overall a better card.

Also a single gpu solution will give you way less compatibility issues.

Eh, compatibility issues aren't a huge concern these days. If all your concerned about is performance, grab another 4830 or 4850. You can snag a 4850 on newegg for $99 these days.

Although the 5770 isn't faster, it is overall a better card. It has DX11, lower power usage, blah blah blah.

4850 xfire is a solid build though, very fast.

I couldn't find one with dual 4830/4850 but this will give you a good idea. Your dual 4830/4850 will be just maybe 1,500 behind the 4870x2. Your single 4830 or the 5770 will be a little less than half of that bar. Maybe 6,000 total. As you can see, dual 4870's are much faster than a single 4890, and faster than a 5850. So I can assume dual 4830/4850 would be a little slower than a 5850 or a little faster, depending on the games and resolution.

There is 1 4830 for sale @ Newegg.

But for the money I would get this 4850 instead.

It costs the same but comes with a double lifetime warranty.

Even if you overclock the 4830 your crossfire will still only be 4830 x 2. Fewer stream processors 640<800

A wee bit off topic, but I was wondering. Look at ATI going over 1400 stream processors on there newest cards. Nvidia has very good cards with only 216/240.. What's the benefit in sooo many stream processors?

If you look at the architecture as a whole, you will see the nvidia and ati cards are different in more than just stream processors. They both have different approaches to delivering performance.
