Before I say anything, my range is 400-500 dollars USD(which I should be getting in March). I'm no PC gamer, nor I really care about the higest settings when I do. Games being playable is all I care about.
I mainly use the computer for Adobe programs like PS, Illustrator, InDesign, Fireworks, Dreamweaver, Flash, ect, ect. I also used Painter at one point but stopped since my current computer started crashing. Multitasking with these programs would be cool, but not necessary. What I care about is speed, but nothing high end.
Another important thing is it being easy to maintain. My current computer started having overheating problems and even though I changed the fans, and blew out the dust, I could not resolve the issue. We live in a poorly ventilated house, and due to this we never use Air Conditioning. My room gets really, really hot and while I don't mind it, my current computer suffered for this. These days I can't even use it without waiting for the temperatures to drop >_> I'm not sure if this is a realistic demand, but a computer that can survive in a hot room would be perfect.
Another thing I'm looking into is recording games, video editing, and maybe 3D modeling. With that, think that's about it.
Anyone got any suggestions? PC or Mac, I don't really care. Leaning towards PC more though.
