Is it possible for me to use a mini PCIE adapter with the HP Pavillion 550-a114 and then install an external graphics card. I heard the Pavillion is basically a laptop in a case. So would I be able to use the adapter and use a better graphics card.

Just checked on mini-PCI Express, and as I thought it only supports x1 (one lane) of PCI Express bandwidth. That's 1/16 of the bandwidth available to a regular PCI Express x16 (sixteen lane) slot. Translation: It'll be really slow compared to an internal GPU, regardless of which graphics card you choose.

your problem will be the types of external cards you can use is limited by the USB3.0 plug. If you had a firewire port i could point you to a lot of improved GPUs over what you have. But with USB3.0 being the limit, I don't think any external drive will be good enough to be an improvement over what you have.

He's thinking you're going to use a USB 3.0 external GPU. You did say mini-PCIe, right? Personally I've never heard of a firewire external GPU. I would be interested in learning more. Perhaps he means Thunderbolt?

ERK - yes i meant thunderbolt

data transfer speeds, good gpu are data crazy.

USB, which runs through the system's southbridge is WAY TOO SLOW to support even a low end gaming gpu. thunderbolt runs through the system's northbridge just like PCI-E does.

As you noted initially, that is basically a laptop in a case.
You can't do much to upgrade it.
