Graphics Card or Lan Rig

Here are the specs of my current rig:

CPU: AMD A10-5800k APU (4.2Ghz Quad core with Radeon HD 7660D put in the CPU)

RAM: Corsair Value Select 8GB 1600Mhz (it's cheap, it works, that's all)

HDD: 500 GB Western Digital Caviar Blue (used to have 1.5TB Seagate Baracuda Green Drive, but I broke the bracket on the SATA data cable when moving between cases) =(

Mobo: ASRock FM2A75M-DGS (just a mATX FM2 mobo, no frills other than USB 3.0, it also suposedly kinda crossfires the GPU in my APU with a dedicated Graphics Card)

Case: Corsair Obsidian 550D (I realized too late that the case was waay too big, and felt dumb)

So, the question is, should I get a dedicated Video/Graphics card or build a LAN rig for when I go to my friends' houses?

You could always just buy a smaller case and a dedicated card, then just sell the 550D. That's probably what I would do. 

 

PS.. I saw you in the live chat.   -.-

I suggest a new case and move your stuff over - spending time with friends playing games etc is a highlight of my teens so I highly recommend.

Okay, thanks you guys.  Any graphics card in particular that I should get?
