I am more familiar with gaming builds (which I've only tried designing 2) and would appreciate help finding cheap parts that will work together for a fantastic quality non-gaming PC.
Parts Not Required: From scratch.
Preferred Website(s) for Parts: newegg.com, but any place is fine!
Parts Preferences: AMD = better bang for the buck (but I am unfamiliar with AMD)
SLI or Crossfire: no
Monitor Resolution: 1024x768 or better
Additional Comments: A friend of mine was wanting a dirt cheap computer for his daily needs. OS can be XP or Windows 7. He will be mainly using it for internet and youtube videos. Wanting it to run smoothly and quickly for this task.
look at hp or dell web page for sales. there comes to a price point on a build that these vendors are cheaper then calling up new egg and trying to piece a unit together. the amd apu (you have to read the spec do come with a low end gaming gpu built into the cpu.) you friend will be able to go some games with the low end amd build. just let you friend know if he does go with a pre built system for the price other then ram and a low powered video card that about it for upgrades on some of these unit. some of the new unit have very low wattage ps and you cant upgrade them.
Nothing beats the Llano for low end builds.
Locally the A8-3870K kit is $199.99 with a gigabyte micro-atx board.
(make sure the board supports the older analog vga since some now have ditched support for the old svga connector in favor of dvi and hdmi)
A Cooler Master Hyper 212 EVO CPU Cooler (about $35) is worth it so you can overclock. (The side cover may have to be left off if the "free" case lacks fans or the cooler is too tall)
A 8gb or 4gb ddr3-1600 mem kit.
The 400 shader gpu o/c well to about 800 to 900mhz. A quad core cpu at 3.4ghz to 3.6. make sure you test with prime95+furmark at the same time to be sure for 10 mins. Small voltage increases are needed.
$300 means you must find a "free" case+p/s.Maybe a working crt monitor. Maybe do some "alley shopping" here. A $20 p4/athlonxp system with a case, ps, winxp os, monitor, key/mouse/speakers might be a good option. (and hopefully a working 80gig sata drive, lol. )
Hint: Get your cash strapped buddy to do this work for you.
A used sata hdd and borrowed sata or usb dvdrw( to do the install) will be needed.
Winxp works with the Llano so this saves you some cash.
Make sure you set the sata in the bios to "ide mode" so it works with a existing winxp install or older version of winxp.
If the power supply connectors are the old "p4/athonxp" style don't worry. Plug the atx connector on the board, and the 4 pin "p4" connector on the board, the empty 4 pins on the atx connector and the extra 4 on the new 8 pin one on the board are not needed on the Llano. (at least with asus and gigabyte fm1 boards anyway).
