I've been using a kinda low-end computer for my PC gaming needs for the last few years, and it's served me fairly well. I've been playing most games on low or minimum settings, and I've been basically fine with it that way, but since I've got a bit under £500 (or around $800) to spend, I thought I should finally see if there was anything I could do to make things run a little smoother. The current specs are as follows, copied from my system information since I don't really know what's important and what's not:
Motherboard: Dell DXP061
Processor: Intel Core2 CPU, 6600 @ 2.40 GHz, 2394 Mhz, 2 Cores, 2 Logical Processors
Video Card: NVIDIA GeForce 8600 GTS
My PSU apparently only puts out 375W, so I've already earmarked £70 to replace that with a 750W one. Which should be enough? Probably? Likewise, I'm already going to upgrade to at least 8GB of RAM, as well. So call it £400 to spend on whatever else. Replacing everything sounds like an expensive hassle, but I don't really know how much of this stuff can be salvaged, so who knows. I don't really need top-of-the-line equipment, but it'd be nice to have things run smoothly at mid-settings, at least. Any advice?
