So for any of you that have followed trough my story about my PC crashing and making me troubles-it was the GPU and it died completely last month. The rest of PC was fine and I sold it for 200 euros. I am currently in process of saving money for a completely new gaming PC in 2017. Currently at 900 euros.
These "Ultra Fast" and "Extreme" gaming PCs on eBay are sad. I really hope no one falls for them. I gotta thank everyone who helped me check my components compatibility.
I'm feeling way more confident now and makes me disgusted that I put parts together in 5 minutes, checked the compatibility and then compared the "Ultra Fast" 8370D to a 780 Ti… Not even necessary… I hope no one here has ever fallen for this, or anyone else viewing the PC. :/
