Need recommendation for graphics card for dual monitor (3007 + rotated 2007) setup - current card has poor performance
I've been using a PCIe Radeon 3600 Dual DVI-dual-channel card to drive my monitors in the above configuration - that's a Dell 3007WFP at 2560 x 1600 on one port, and a rotated Dell 2007WFP at 1200 x 1600 on the second port. This is all under Windows XP SP3. I have had constant problems with screen artifacts remaining behind after windows were moved.
I switched to a Radeon 4350 card with a DVI-Dual-Link connector (for the 3007) and a VGA connector for the 2007. This works, but screen refreshes are slow - dragging a window around leaves trails behind that take a while to go away. Screen redraws are slow.
I suspect some of the screen redraw slowness is due to the rotated screen. I don't know whether to try a newer ATI-based card (Radeon HD57750 or HD5770) or to switch to another manufacturer. Gaming is not a consideration - work is 98% 2D applications with some occasional video - just moving around lots of windows. Cost is important - I'd prefer to stay under $200. Any expertise out there? Any suggestions for where to spend my graphics card $$?
