First the requisite system information: Acer Aspire E380 AMD Athlon 64X2 4200+ 2.2ghz, 2GB PC5300 DDR2 Ram, 320GB HDD running Windows Vista Home Premium x86. So far the only thing I've upgraded on it is the RAM, went from 2x512 dual channel to 2x1G dual channel. Now the questions, I'm looking to upgrade from the built in Nvidia 6150SE chipset to a dedicated Video Card, I don't run the newest games but do watch a lot of movies and pictures on it and wouldn't mind playing a few games that I know are coming out soon. I'm open to all suggestions. I'm looking to stay under $100 and DX10 is an absolute must. Also since I upgraded the RAM to 2x1G would there be a noticable increase in either speed or power to put the 2X512 back in and not dual-channel?
