You need to upgrade your processor before you upgrade your video card. No matter what video card you buy you are not going to see that big of an improvement without upgrading your processor. If you don't want to upgrade the processor then don't bother spending more than $150 on a new video card. Your computer can last as long as you want it to, all you need to do is upgrade some parts whenever you want to catch up with the latest technology. There is never a need to scrap it all and start fresh.
