I wanted to build a PC, but one of my associates has bought this PC ( Specs given bellow) It is only 1250$ i never seen it for this cheap the company is offering a discount its original price was 2000$ i am a bit skeptical about this i never seen AMD r7 450 gpu which has 4gb vram and why is the company selling it this cheap? Oh the device name is DELL optiplex 5050 MT XCTO, i googled about PC and i found no results please help. And i know its not a gaming PC i am trying to achieve a balance between gaming and office work. Edit: I called the sales person he agreed to increase the SSD to 250gb and decrease the ram to 16gb, he says that he cant agree about the GPU change to Nvidia or any other amd he said he wont give warranty or anything like i can place it but the damages are not accountable.
