Need opinions before i commit to a build

building a computer for my mother, and i just want some peoples opinions on it.

price range: $500 max, preferably $400-ish
what it will be used for: ms office, videos, basic windows games, maybe other games in the future.
don't need: keyboard, mouse, monitor or speakers.

my current selection:
CPU: A8-3870K - $79
MOBO: GA-A55M-DS2 - $49
PSU: Corsair CX430 - $65
HDD: Seagate Barracuda 500GB - $60
ODD: DVDRW, samsung - $19
Card Reader: ICY BOX Card Reader - $35
Case: CoolerMaster Elite 341 - $39
Memory: G.Skill Ares 1866MHz (2x4GB) DDR3 - $55
OS: Windows 7 64-bit - $95
total: $496

i'm in australia, and using "www.pccasegear.com" for my prices.

a few things i'm considering:

1. how much better would the a10-5800k be over the a870k? the website i'm using has the A10 at $135, and a FM2 socket mobo would cost at least $65. so would the extra $72 worth it for the improvement? (would she even notice it?)

2. i've heard that memory speed has a significant effect on integrated graphics, so i went with 1866MHz ram. is this overkill, or should i save $10 and downgrade to 1600MHz?

3. 8gb of ram, or maybe 4gb for about half the price?

4. i can save $95 by installing Ubuntu instead of windows. is it possible to share files on a network between computers running different OS?

5. is there a CPU + discreet graphics option that is more cost efficient than the A8-3870k?

6. the motherboard has the a55 chipset. normally, i would have gone for a a75, except that the site i was using didn't have any. the main difference is that the a55 only has usb 2, and sata 2. am i right to assume that usb3 and sata3 devices can still be used, but will run at usb2 and sata2 speeds?
if not, could i use the PCI or PCIe slots to add in a usb3 card?


Thank you in advance to everyone who read and tried to answer my questions. :)

    If you plan to game, you really need a descrete card.
  2. i may have over emphasized the importance of gaming, it is a fairly low priority. windows games, maybe some online flash games, probably never anything that would have to be installed from a disc.
  3. System seems nice to me. Regarding the A10, I don't think she'll need more than an A4 :lol:
