Hey I'm planning to get a new computer by the end of August hopefully, or wait for a black friday sale. I want to stick with AMD processors because they are cheap and IMO reliable. I will play some games on this machine like Skyrim, Diablo and Fallout. I'm hoping to keep this computer for 5 years and occasionally buy a new video card when the Nvidia 500 series gets cheaper. I already have a mouse and a monitor from my dad. My original budget was $700 dollars so any money saving tips will be helpful. If you read all that hats off to you.
Wouldn't recommend getting an SSD at this budget honestly.
AMD is not the route, specially at this budget. The board you chose is also pretty expensive, lop siding the build. Whats most important is the GPU and CPU as you stated. The case is also way too much for the budget. Don't cheap out on a PSU.
Well... Considering both are only roughly $10 less it is your choice whether or not the difference is justified.
The GTX 560 SE is even worse than the 6870 by a long shot. If you have no complaints with the 6870 you can just use my $650 without upgrading the GPU. Just keep the same refurbished hard drives and get windows where I suggested for less.
