The HD6450 is entry level card where the HD5670 is a gaming card. A card with the same GPU running DDR5 ram is faster than a card with DDR3.

The HD 6450's performance is about the same as the HD 5550's performance. The HD 5670 is the better card. DDR5 RAM is faster than DDR3 RAM so it will help with performance a little bit.

The issue you have is your old Intel motherboard. It is has a PCI-e 1.0 video card slot. Current video cards either have a PCI-e 2.0 or PCI-e 2.1 interface. Some motherboards with an old PCI-e 1.0 slot can have compatibility issues with a PCI-e 2.1 card. Therefore it is better to buy a video card with a PCI-e 2.0 interface.

That means avoid all Radeon HD 6xxx cards because they are PCI-e 2.1 cards. Additionally, during the middle of the Radeon HD 5xxx series, the cards switched interface from PCI-e 2.0 to PCI-e 2.1. Therefore, most of the HD 5xxx series cards can issues with your old motherboard.

You need to specifically look for a video card which states PCI-e 2.0 like the following HD 5670 512MB card for $63 after rebate + $3 shipping:

Lastly, the HD 5670 is basically too slow to more than 512MB of RAM. The performance difference difference between a HD 5670 1GB and HD 5670 512MB is at best 1 or 2 frames.

If you really, really, really want that potential 1 or 2 more frames, then you can buy the following PCI-e 2.0 HD 5670 1GB card for $95 + $5 shipping:

You can buy the following 430w Corsair PSU for $20 after rebate. It is more than enough for your system. But can limit potential upgrades a bit.

The following 500w Corsair PSU for $40 after rebate can allow for even more upgrade potential:

Both PSUs are manufactured by CWT (for Corsair); they have good reputation for building PSUs.
