Graphics card upgrade or new tower?

[Bramptonion]

My comp specs: AMD Athlon 64 x 2 Dual Core Processure 4200 1024 mb./ 320 gb. Nvidia GeForce 6150 LE I would like to upgrade my graphics card to be able to support 2 monitors (preferrably DVI connections) Is it possible to simply upgrade the card, or is a new tower the best option? If i upgrade the card, will i have to upgrade or add more RAM? and will this last a few years before having to upgrade again? This is a work comp for 2d CAD (mainly), minimal 3d CAD and rendering. Any and all recommendations are greatly appreciated. Steve

what does a new tower going to do?
graphic card would be the way to go.
you should have at least 2 gigs ram.

ps it also depends on what money you have to spend or want to
