Hi there,

I am contemplating on a new-to-build system, and noticed that when only looking at price tags of the cards, two 4830's in crossfire are about the same price (within 10%) of a 4870 1gb.
So I am looking for benchmarks of the two, but can't seem to find one on the net. Is this just a ridiculous comparison (due to secondary problems, power, compatability in apps, etc), or just nobody tried it yet?

Furthermore I am wondering about the AVIVO video in capabilities of the cards. According to this article:
http://www.tomshardware.com/reviews/video-capture,1527....
it should be no problem to capture video on an ATI card, but after referring to the ATI/AMD website I am not really convinced that I will be able to plug in my AV signal and record it...

BTW, this system will run on a samsung T220 (22inch) monitor, so maybe I am just way over the top thinking of crossfire or 4870 and should just stick with a single 4830?

Best regards,
Matthew

Many games don't get much boost from SLi/CF only about 30-50% most of the time, secondly 2 4830's can have compatibility problems and they use more energy. Also you should consider the normal 4870 and the GTX260 (216). If those 2 are the only practical option due to supply, location, or other problems then I would get the 4870 1gb.

In my opinion you would be better off with the 4870, seeing as how crossfire support overall isnt super. Also later down the line you can always add another 4870.

Here is probably the review you were looking for, but I believe they used the 512 MB 4870.

Thanks for that one. Though, while lacking additions to the name of the 4870, I am assuming it is indeed a 512mb card, which has been compared on this site as well.
I am BTW not opting for NVidia as they will surely not capture video.
The future expansion adding an extra 4870 1gb is a strong argument to go for that one.

Thanks a lot
