Hi, I am planning to build a gaming PC for around $500-$800. Although I am still debating whether or not if I should upgrade my Dell Studio XPS 8000 instead. The specs of that computer are: Intel i7 processor, 8GB ram, GTS 240, 350W PSU. My current computer has very little room to upgrade, I have researched and I would need to upgrade the PSU and the graphics card but then I run into a problem with the air flow. There is very little room inside the PC and it will overheat when I am playing video games. The GTS 240 will be idle at 90C with a GPU load of 1%-10%. I am wondering if it would be better to build a new gaming PC or upgrade the Dell Studio XPS 8000.
