Can i put a GeForce 9800 GT into my Lenovo desktop?

It's like one of those all in one touch screen desktops. Can i put that graphics card in for gaming or would it not work? Right now it has an Intel(r) HD graphics card.

I wouldn't think so, that's the problem with all in one's, limits upgrading to maybe just RAM and hard drives. Should got a desktop.

As long as you have room, have a 400W PSU (or more), the proper PCI-Express slot and the one 6 pin PCIe video power connector on your PSU, yes, it should all be fine.

That all said most touch screen, all in one desktops, are not upgradable for video, never will be…

Sorry, but no. All-In-One systems are basically a laptop that has been designed for desktop use. AIO's also have the same limited upgrade potential as a laptop, which is limited to upgrading the hard drive and memory (RAM) only.
