Hello there. I'm trying to build a very nice PC (for the money I have to spend), and I'm in a bit of a conundrum. Should I get a regular PC configuration, with one video card, the Radeon HD 5850 (which, supposedly, is better than even the nVidia GTX 465 (?), even though the 465 is listed higher at videocardbenchmark.net), or get a Crossfire type of configuration, with two Radeon HD 5770s (that would cost a bit more) or maybe with two 5750s (that would cost exactly as much as the 5850)? (Money is a bit of a factor, too.) I understand that: 5850 - has core clock of 725 MHz, 1 GB of memory, and 256-bit memory interface 5770 - has core clock of 850 MHz, 1 GB of memory, and 128-bit memory interface 5750 - has core clock of 700 MHz, 1 GB of memory, and 128-bit memory interface, but also 2-DVI, unlike the 5770. It would be very nice to have 2 GB of video memory, and two GPUs working in tandem, but I'm still not sure whether it's an upgrade over just the one, better video card. It is, right? I also am not 100% sure what kind of motherboard I should get for the Crossfire option, if I decide to go with that. (But I know I wouldn't like to pay more than 150 dollars for just the mobo. Oh, and it has to be able of full HDMI, of course, otherwise what's the point, right?) How's the Asus AMD785G M4A785TD-V EVO? Is it good for Crossfire? Oh, and having two GPUs... would that need some extra cooling fans in the computer case, too? Sorry for asking so many details. Thank you very, very much.
