How should I upgrade my PC?

I am thinking about upgrading my PC so I can max out newer games. I am quite a noob so please tell me what to upgrade and how much it would cost. My specs are:

CPU: Intel(R) Core(TM) 2 Duo CPU E7400 @ 2.80 GHz

CPU Speed: 2.80 GHz Performance Rated at 5.04 GHz

RAM: 3.5 GB

OS: Microsoft Windows XP Professional Service Pack 3 (build 2600)

Video Card: GeForce 9500 GT

DirectX version: 9.0c

Sound Card: Realtek High Definition Audio

Video card and Operating system

EVGA 01G-P3-1371-AR GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

Microsoft Windows 7 Home Premium 64-bit 1-Pack for System Builders - OEM

That card would bottleneck his processor though.

Any cheaper videocard that would be almost as good as this one?
