Best Graphics Cards For The Money: June '09
This month, ATI's new Radeon HD 4770 is missing in action, since online stores are not only unable to keep it in stock, but also de-listing it completely. With violent movements in pricing, though, it'd have been taken off the recommended list anyway. Read More

With the recent release of ATI’s Radeon 4850, we’re seeing a whole bunch of 4850 cards cropping up all over the place. The cat is barely out of the bag but we’ve already seen boards from Gigabyte, Asus, PowerColour, VisionTek, HIS, MSI, Diamond and Sapphire.
It’s a little early in the game for comparatives denoting which card is better and what company it came from. Immediately following the launch of a chip it’s quite normal to see a rake of products from manufacturers that are, for all intents and purposes, pretty much the same deal. Major differences will be limited to the software companies include in the retail box (games, utilities etc), minor clock speed differences (+50 MHz or so) and connectors (DVI, HDMI, VGA, Display Port, etc - as well as combinations thereof). Later, say in about a month or six weeks, we’ll start seeing companies trying to differentiate themselves from others with better cooling and extreme editions.
Below is a list of some of the major manufacturers and specs for the 4850 cards they have on the market.

What, did you just steal those from newegg? Some specs are missing, And I would rather have benchmarks and warranty info on all of the cards.
Ummm... They're all practically the same.
I think diamond wins the sticker competition here! hehehe
"...for all intensive purposes..."
tee hee, it's "for all intents and purposes".
Good thing all those benchmarks made up for that skip, oh wait.
LOL they taken old HD3870 specification and even didn't changed it,few more manufacturers made similiar mistakes ...
"Official Product Specifications for the Diamond HD4850 GPU: HD 4850
Transistor Count: 666 million transistors on 55nm fabrication process
"for all intensive purposes" - lol
If you are going to write a column, you really shouldn't write it half fast - lol again
"...for all intensive purposes..."tee hee, it's "for all intents and purposes".
I saw this exact phrase in an article somewhere else on the site last week. Looks like they need to add this one to their auto-correct dictionary.
