Im going to be building a new PC to be used for gaming and am tring to build it as cheap as posible without sacrificing performance obviously.
i dont have PSU, Heatsink or monitor chosen yet and would like some input on these please.
Looks pretty good. But get 2 x 1024 of RAM, not 4 x 512. Won't really cost more, and it'll save you from killing any upgrade paths like you currently show.
And IF you are really interested in C2D, then look at a 4300 and MSI 965 Neo-F for CPU/mobo. Both are very inexpensive and will perform just fine for non-overclocking situation. Definitely worth a look, you might be surprised actually that a C2D is in your budget.
