Best AGP Card For ~$115

The 2600 XT is relatively new to the AGP scene, but almost as cheap as its PCIe cousin. This is the fastest DirectX 10 card available for AGP at this time, and surprisingly offers a great deal of performance at the $110 price point. In addition, this card has the power to accelerate the entire HD video pipeline - we haven't tested it, but in theory, this card should enable demanding HD-DVD and Blu-Ray disks to be played on older CPUs.

Best AGP Card For ~$130

The X1950 GT is a slightly underclocked X1950 PRO, but for noticeably less cash. You won't find a better deal for upgrading your AGP rig, and let's face it: you probably don't want to invest all that much money into an older standard that you can't migrate to your next PC.

Best AGP Card For ~$235

The X1950 XT - manufactured exclusively by Gecube - is simply the most powerful card ever to grace the AGP bus. This card's closest competition is the XFX 7950 GT, which costs slightly more but is a lot less powerful.

At $235, it is a bit of a tough pill to swallow for a dying interface. I would only recommend the X1950 XT AGP to someone with a very fast AGP system who already has a power supply with enough juice to handle the X1950 XT.

It must be noted that if you have $235 to spend on an AGP card - and possibly an extra $100 for a power supply that can handle it - you may be much better off purchasing a PCI Express motherboard, CPU and PCIe graphics card.

PCIe graphics cards are cheaper than their AGP cousins. If you upgrade your system to PCIe and sell your old components, you may actually spend a similar amount of money compared to buying an expensive AGP card alone.
