Check out the G450 Matrox or the ATI dual monitor card. I'm running dual monitors and once you do you can't go back. you can buy the second monitor later. the G450 has one of the fastest ramdacs out there and 32MB of DDR Also check out the deals at accessmicro or axiontech or streetprices. many places have bare bones systems that you can put together. just takes a screwdriver. then add on the RAM and video card. it really is simple. and most places have good enough tech support. tom's hardware has very good guides for building overclocked or just solid systems. tells you all about the best motherboard/cpu combos
