I am hoping to get a new PC customs built for flight sim and air to air combat sims. I am unsure of the spec I require. I want something that is 'future proofed' and can handle the complex data involved in such software without falling over. So, I'm thinking of a spec along these lines. An i5 or i7 Intel pentium processor, of at least 3.2GHz, Quad core. 4 to 6GB of RAM 1 TB HDD Graphics/video card. Can anyone suggest a good one? 800w PSU Big fan to keep it all cool Any suggestions/comments. I don't want anything, initially that is not essential, but want good performance, especially with scenery files. I have approx £1000 to spend.
