What is a good affordable desktop?

I'm looking into desktops and I would like one around $700-$850 I want about 8 gigs of ram and decent for games like minecraft

Www.ibuypower.com is a reliable website, just customize one of their desktops to your price range. I would suggest a Radeon 7770 for your GPU, and any quad core 3.0 or greater CPU. Everything else is up to you.

If you want cheap functional with decent specs I go with acer or dell going by specs don't buy apple it costs like double for equivalent specs

This is what I would suggest. It is identical to my build, which runs Minecraft with everything full at around 140 - 180 FPS. With this you can actually play everything on High. However, the build is at almost 800$ without a monitor and peripherals since I don't know if you want them included in the price.

You could try this specs if you are not looking for super powerful machine

AMD Black Edition - AMD FX -6300 3.5 GHz 6-core Processor = 110 dollars
ASUS M5A97 LE - 2.0 motherboard = 90 dollars
segate hard drive 1tb = 100 dollars, 500 gb = 50 dollars
Kingston HyperX 8 GB = 80 dollars
ati radeon 7770 video card = 130 dollars

that would be like 510 dollars you can choose another gpu
