Ok, so I know I want an AMD FX 8350, Asus Sabertooth 990FX R2.0, DDR3 1866 MHz RAM, some form of the 7870 GHz edition GPU, and possibly a new case. I already have a PSU, HDD, sound card, and case. But like I said I would ossibly like a new case if it can fit into the $800 budget. My Antec 900 just collects too much dust and cleaing it requires a lot of disassembly.
This is probably the cheapest it will get. http://pcpartpicker.com/p/BOtB
Edit: I accidentally put a 7970 GHz chipset in, lol. Here's the real thing. http://pcpartpicker.com/p/BWNx
He said 7870 so the budget will hold.
Yes, it would cost around 650 Max for your components. Since your looking into a 7870 I recommend the MSI Hawk 7870, it's OCed to 1100Mhz.
Why on earth you went with that ram I don't know.
I forgot to mention I am not overclokcing. So the stock cooler for the CPU will be fine for me. Also I prefer mid tower cases. Toast are you asking me why I am going with DDR3 1866 MHz RAM or are you asking ghettohamster36 why he chose the RAM he did? And Foxy that card looks like it will fit my needs but I'm not sure if tigerdirect.com (retail outlet near my house) will have that in their store when I go tomorrow to pick out parts.
This is the 7870 that you're going to want.
You could get the card that Oxy recommends (It actually is better than a 7950) but I'm more than positive tigerdirect doesn't have it.
