I'm looking to get a new desktop....looking at Dell's Vostro systems based on some good write-ups on this board. I'm torn between the Dual core 3.0 Ghz or the 2.4 quad. I know the Dual core is probably the better choice right now but will the quad be more future proof? I don't do automated systems or tons of backtesting so I realize that the system will probably be overkill. Plus, none of my software supports quad core. Also, any need for a 256 MB video card instead of the 128? Thanks for any advice!
