I have a Pentium 4 CPU 2.66 GHz 230 W 4Gb of DDR RAM GeForce 6200 512Mb DDR2
I will use this to run two HD monitors 1920x1200 for visual studio on windows XP and eclipse on linux
Is there a better video card that would still run on my (only 230W) power supply?
On board video was useless even for moving windows around: shared memory max was 32Mb, so going to 512Mb ona graphics card was a noticable improvement, but moving a window diagonally still leaves non-refreshed area for almost a second (on linux, better on XP)
Would upgrading to 1Gb of memory even be noticale for regular move/resize/scroll window content type work (no gaming)?

the ram should not be a problem. there are very few cards available that can run on 230 watts but you may try something like a 8400 gs or a 220 gs.
It's not lack of video memory, it's lack of processing power. Graphics card speed isn't directly proportional to it's memory.
