Definitely would be a lot easier to build it inside the case first, I could see issues screwing in the motherboard with everything on it lol.

I'd go for a bigger upgrade though, the Radeon HD 7850 isn't that much better than what you have. I'd personally go up to the R9 270x or if you want the Nvidia equivalent go with the GTX 660 Ti

R9 270x Newegg.com - XFX Double D R9-270X-CDFC Radeon R9 270X 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card
GTX 660 Ti ASUS GTX660-DC2O-2GD5 GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card - Newegg.com

They're going to cost a little more, but you'll probably get an extra year or two for being able to run games on max settings.
