Yeah I wouldn't hold my breath on an update.
The surprising part is, that gateway still exists. o.o I haven't actually heard about the company in at-least 10 years.
Still some options could be to get another LGA1155 motherboard and swap it out. (You could get a Dual-GPU capable board.)
Or swap the PSU out and go with a higher-end Radeon.
The Quad-Core Sandy Bridge3.0-3.3ghz CPU is still pretty potent, so it makes sense to stick with it.
