I have a Dell Inspiron 560. It has Core 2 Quad Q8300, Ati Radeon 4350, 16 GB of ram, the latest version of Windows 10, 500 gb 7200 rpm hard drive, and the stock 300w power supply. I want to upgrade the GPU and the Hard drive if possible, I am not sure about the motherboard but it’s probably full ATX. Could you all also recommend a motherboard with 4 slots for DDR3 RAM which can also overclock and a good power supply with it?
If you like to tinker and want a DDR3 system that’s good for overclocking I’d get a Sandy Bridge K series processor (2nd gen, 2000-series) and a socket LGA1155 motherboard with a “Z” chipset. Sandy Bridge has a pretty good reputation for overclocking and was even still competitive for gaming until a few years ago, particularly when overclocked to 4GHz+.
With that said, I’d only really go that route if you are trying to put together a vintage gaming machine or just like to tinker with things. Otherwise, you’d be better off putting your money towards something newer. Intel 6th-8th gen ex-corporate Dells are widely available and are pretty cheap.
