DisplayPort is the most fun when you snag it on the cheap, and according to some leaked specs over on Madbox PC, AMD has a $50 Radeon in the works that'll have you running that 30-incher off of USB for a pittance. The Radeon HD 3450 card is based on the RV620 core, running at 525MHz, with 256MB of RAM and just a VGA plug to accompany the DisplayPort. The HD 3470 ($60) hits 600MHz and 512MB of RAM, and does DVI, while the HD 3650 ($100) maxes out the trio at 800MHz, with 512MB of RAM as well and the RV635 core to back it up. You might not be thrashing around in Crysis, but HD video and perhaps some last-gen shooters should be totally within your grasp whenever AMD gets these to market.
