Hello Bit-tech, I have recently built myself a computer out of some parts I have purchased and others donated by a friend. Here are some of the components I have at the moment: Intel i5-2500k 2 x 2gb DDR3 RAM - Corsair 500w OCZ PSU Asus P8H61-I Motherboard HD 4890 I would like to get a new motherboard but I do not know which one as I am relatively new to this. I am looking to upgrade the HD 4890 to a GTX 560 ti and understand that I would need a new power supply also. What are your recomendations? My price range is somewhere between £60 - £90. Thank you for your time.
