Upgrading My Graphics Card.

[AaronJMurphy]

Hello Everyone.

I'm planning to upgrade my graphics card. (If I can) Any recommendations

System Quick Spec:

Pentium 4 HT - 3.0Ghz - CPU
4GB RAM
160 GB SATA300 (SATA-2) Hard Drive
ATI Radeon HD4550 512MB Dual-Screen Graphics


Also the PC looks like this: (Image is from Ebay)

HD 4670.
Anything higher will be bottlenecked by the CPU.
Pentium 4 is actually a single core not dual core.
