I don't have a hard budget, but I've been spending the last month or so casually looking through the current available hardware to decide what to build.
I'm going to be using my old computer case, PSU, HDD, Optical, and a PCIe x1 wireless adapter. I only note the wireless adapter because I have seen one ATX board that didn't have the ability to place wireless and GPU. PSU is a Corsair TX 750W and is about 5 years used.
The problem I've found with putting together a budget build, is that while the AMD chips seem to be able to OC well, a more expensive board is needed. And so my current thinking is to go with either a FX 6300 and OC it or to go with a 3470 and not OC.
I'm looking to spend around $500-600 for GPU, CPU, Mobo, RAM. But like I said, I don't have a hard budget. GPU will probably be a ColorPower 7950, ColorPower has two 7950s and one is a decent price right now, $215 after rebate.
So the questions are kind of, which combination of CPU+Board will get me better price/performance. FX6300 is about $70 cheaper than a i5 3470, but I think it would need a more expensive mobo than if I went with a I5 3470. So I guess I'm looking for ideas.
edit:I also have another thread open with a potential build if anyone wants to look. Topic is pretty similar to this thread.
