After becoming frustrated at how limited my laptop is, i've decided to build my own computer with a budget of around £450 ($650ish USD). I've chosen what components i'd like but would they work together and function as a budget gaming rig?
Assuming you're not wanting to spend £200ish or more?
I'd strongly recommend a PSU from a quality manufacturer like Seasonic, or XFX (who do rebadged Seasonic PSUs generally at a better price). You know Ebuyer have the GTX650 Ti at £94? It's a lot faster than a 7750.
