Firstly my budget has come up to roughly £450-500 . Secondly, I am using a monitor at resoloution 1920x1080, and I really dislike lowering this for playing games. On my current computer, I attempted to play GTA IV, and considering this pc isn't that old it was dreadful at the lowest res. My graphics card isn't brilliant (9500gt!) but I have also heard the CPU has to be excellent to run GTA IV, especially at such a high res. I dont mind playing a mid to low graphics settings, so I was wondering if anyone had some advice on the processor/graphics card/motherboard combo for the best price, please check my link for the pc I plan on building.
