Looking to build a new gaming machine with an existing GPU

Hello!

I was initially going to ask advice on CPU upgrade, but it looks like I would need to do pretty much a complete overhaul since my motherboard still has a AM3 socket.

I am looking to replace my motherboard, cpu, and ram. I am happy with my graphics card (and I obviously have cpu cooler, optical drive,etc), so I want to build my machine around it. I am running with a 650W PSU and I have not had any problems with it, so I'm hoping it will be okay for this new machine as well. I live in the US so Newegg, Amazon, TigerDirect, or any other US base companies are fair game.

My graphics card is Asus Radeon HD 7870 , and I don't plan on doing anythign crazy so I'm looking for the cheapest setup that won't bottleneck my GPU. Any advice would be much appreciated.

Thanks!

  1. 4670K and a Z87/Z97 motherboard are good options.

    A cheaper route would be going with the FX 8320 and a AM3+ motherboard.

    All great options, get whichever one you can afford.
  3. http://sites.amd.com/us/documents/amd_fx_performance_tuning_guide.pdf the most important thing to take from the guide is that the best speed for your cpu-nb is the speed your ram is running at plus 1 sticks speed.

    Never skimp on the motherboard. The better voltage differential from a 990 chipset makes a large gaming performance increase for the fx chip.
  4. i would go for the i5, is better for gaming
