So I built my new PC about 3 weeks ago, and I was originally going to get the XFX 7850 2GB, but the dude at the store gave me a XFX 7850 1GB instead. I didn't realize until after I built the PC, I looked at the box and I read it thinking "are you kidding me?" How bad is this? Is there really that big of a difference between the 1GB model and the 2GB? Because I honestly feel like I've been ripped off right now.
