Afraid GPU wont fit into my pre-built Acer PC. Help!

[songzhe94]

I have a Acer aspire pre-built pc (link to specs are below) and i want to upgrade the old GPU. Problem is, i'm afraid of getting a GPU that wont fit. I've compared the GT 620 (Current GPU) with the Nividia GTX 750 and the 750 is only slightly thicker, so i'm assuming that it will fit, hopefully.

Any advice?

The 750 is a dual slot card whereas the 620 is a single slot card. Your system has space to support a dual-slot card.
The problem that faces you is finding a card that is low profile as opposed to full height since that is a Small Form Factor case that you have there.
I'm not sure if you'll find the 750 in low profile though.
