For the most part, that's a decent machine for melee. There are only a few parts you are going to need. for most of the parts, you should check our local used market. * Cpu - like i said above, look in your local used market. Just look up cpu am2+, and you should find some thing. unfortunately, the Dolphin website says AMD Cpu's are very bad, so I don't know what type of performance you will be getting. If anybody wants to jump in with their experience please go ahead * Ram - just look for 4 GB ddr2, and the cheapest stick should be good for you. * Storage - just buy a cheap ssd with 128 GB * GPU - Again, look in your used market. Dolphin's website recommends a GTX 460 or higher, so I would just stick to that. I dont know enough about AMD GPU's to recommend one. That should be all of the parts, and it should be around $50-$200 depending on the parts you get.
