I've put together a rough parts list for my new build and i wanted to see if anyone had any advice. The piece i'm most unsure of is the MOBO: I would like to find a cheaper (but still reliable) one if possible. Any other advice would be appreciated too. My budget isn't really set in stone, i'd spend a little more for a big jump in performance but of course i'd like to spend less. My goal is to be able to play most games at in 1920x1080 resolution. I already own a case, HD and cd drive.
Since the graphics card is the most important component for gaming, see if you can't use the difference to buy a stronger graphics card such as the 7850.
Here is one for $180 after rebate: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
The GTX660/GTX650 will launch soon as a 7850 competitor, you might look for that.
Any of those cards will run on the Corsair CX430. I have used one before, and it seemed to be a good quality unit, and a steal @$25.
If really needed, the i3-2100 at $25 less would not hurt as much as a stronger graphics card would help.
